New engine

[chevyman]

Just a pos 350 .30 over. Comp cam.. 58cc heads

[CamaroRobZ28beer]

so you paint a 350, you have a stock water pump, but oyu painted it, you paint the crappy intake like a retard, you put on the oldest valve covers ever stamped, you have stock iron rockers, and yet somehow you think this is worth taking 8 pictures of?

have you lost it?

[Dunout]

that's what i call a budget build on a vacuum sales boy pay check..

[chevyman]

it is a budget build, and its nothing special to tell you the truth..I spent under a grand to build it and half of the cost was machining..Im not bitching, should be pretty quick. So what it has a stock waterpump and rockers, its not a 400+hp engine.

[CamaroGirl]

wheres the shiny parts?

[Dunout]

wheres the shiny parts?

he cant afford that!

[chevyman]

the paint is shiny lol

[SkullcrusherR7U]

compression?

[chevyman]

12.5:1

[79 Z28]

305 heads on a 350, theres a matched power combo

[chevyman]

should be good

[SkullcrusherR7U]

You and the budget king Allpontiacs should race for slips!

[chevyman]

355 vs an lg4?

Thats just not fair lol

[89vert]

12.5:1


race fuel?

[chevyman]

94 octane

[89vert]

ok

[89vert]

the good news is this engine will match your last 1 soon enough

[SkullcrusherR7U]

355 vs an lg4?

Thats just not fair lol

Hey, don't count out his extra aerodynamic nosecone, he'll getcha on the top end. And depends how well your carb is tuned. If it's botched he might have a chance. :D

[89vert]

that engine won't be fast,

[chevyman]

the good news is this engine will match your last 1 soon enoughno im going to take it easy on this one, I want this one to last a long time

[89vert]

12.5:1 iron head, detontaion much, add cheap pistons and it won't last long

[CamaroGirl]

12.5:1 iron head, detontaion much, add cheap pistons and it won't last long

and they probably are!

[90_383]

ok ok josh , what color is the paint ?..... cuz to me it looks pink

[90_383]

and if its red , then what color is that hood behind it ?

[Jessev]

lol!

[allpontiacs]

You and the budget king Allpontiacs should race for slips!


Why would I want any piece of shit he owns? Besides, he doesn't have any clue how to put a motor together, it wouldn't be a fair race.


12.5 on iron heads with 94 octane? Hahaha you're so stupid

[89vert]

Plus the fact the chamber doesn't match the bore

It's going to create hot spots on the corner

With that kind of compression it'll run on it's own

[79 Z28]

[SkullcrusherR7U]

Chevman sez it will be unfair and so does Pontiacs. Thats good enuf reason to race. Forget slips and just do it. If the LG4 wins it would be endless fodder to rib chevman. Or pontiacs will have to admit defeat to the superior Macgyverism of Chevyman. If a race does ensue, I predict Chev gets off the line first and leads for a bit until detonation grenades it and Pontiacs goes to the winners circle. :p Nothing like 2 homeschooled self proclaimed gearheads running on Lemonade stand budgets gettin it on in an all out grudge match! :rolleyes: I crack myself up sometimes. lol.......I know if it happened everyone here would tune in.

[89vert]

lol

[chevyman]

thats the shit camera i have, the engine is ford red.. its pretty dark in person and ill use the other camera..

[chevyman]

As for the engine grenading and running on its own, it wont happen.

My old man ran the same combo for 13 years in his nova..And raced it for 5 years of that till it chucked a rod bearing..Id say thats pretty good

[89vert]

then its not 12.5:1
unless you are running race fuel

11:1 is pretty fucking high for iron heads on pump gas,

head and chamber design becomes a huge factor too, if you chamber is smaller then your bore by that much the corners will get very hot, in the middle of the bore like that it will cause detonation and dieseling for sure

[chevyman]

well we will see what happens

[89vert]

going to bend the laws of physics?

[mongoose]

a 265@.050" should take care of the extra compresion..

[IROC-Z]

lol, wheres the motor you're gunna beat me with? and where the hell is my $300?

[Dunout]

lol, wheres the motor you're gunna beat me with? and where the hell is my $300?

just face it, its not going to happen and your never getting your money..

[IROC-Z]

just face it, its not going to happen and your never getting your money..

Well I knew from the beginning he'd never beat me let alone race and to be honest its funnier that he doesn't pay, I mean what kinda loser does it take to welch on a $300 bet lol

[Dunout]

i think even drummy showed up?? thats sad

[CamaroRobZ28beer]

thats the shit camera i have, the engine is ford red.. its pretty dark in person and ill use the other camera..

okay, you have 2 cameras for some reason, and for another reason, you keep the one which is shitter than the other. then when you go to brag about a pile of shit motor you decide to use the shitty camera?

seriously? what the fuck is wrong with you?

stop lying or start thinking. or how about both

[Dunout]

best part was Brenda left him for someone better...

[IROC-Z]

Possibly a few steps up the employment ladder like McDonalds or Tree planter??

[CamaroRobZ28beer]

no kidding, i wonder if he owns anything built after 1990

[89vert]

I have an 89 Jimmy and an 89 Camaro :(

[CamaroGirl]

Possibly a few steps up the employment ladder like McDonalds or Tree planter??
way up!

[chevyman]

wow this went to shit

[79 Z28]

tell me the specs, bore, stroke, piston info (dimensions, dome, valve relief, compression height etc.) head size, head gaskets used etc. i will calculate for you the true compression.

[chevyman]

sounds good, ill post it after work. All im going by is what the machinist said, he was a bit weird so he could be wrong..

As for piston dome, valve relief and compression height id have to look it up, seeing as how these pistons came out of a different engine.

[89vert]

You would have to know piston to deck height

[chevyman]

well its a little late for that, the engine is all buttoned up

[chevyman]

the engine has trw flat tops with valve reliefs, 4.030 bore and stock stroke. I cant find any info on the pistons.

[chevyman]

now that i think of it, how can it be 12.5:1 with stock length rods..?

im going to go talk to this clown today and see how he figured this ratio.

[89vert]

well its a little late for that, the engine is all buttoned up

What cc are they

[chevyman]

the heads?

[89vert]

The pistons it's a pretty standard measurement

[IROC-Z]

now that i think of it, how can it be 12.5:1 with stock length rods..?

im going to go talk to this clown today and see how he figured this ratio.

rod length doesn't determine compression ratio dumbass

[86 red dragon]

Nothing like 2 homeschooled self proclaimed gearheads running on Lemonade stand budgets gettin it on in an all out grudge match! :rolleyes:
this sums up cumaro

rod length doesn't determine compression ratio dumbass

lol

[CamaroRobZ28beer]

wow chevyman, the backyard mechanic you are asking about all the info on your motor is really taking you for a long ride

[CamaroRobZ28beer]

I have an 89 Jimmy and an 89 Camaro :(

i know theres a 21st century gas miser sittin in that driveway of yours

[chevyman]

The pistons it's a pretty standard measurementand how do i determine this..i cant find info anywhere on these thing...fuck

[chevyman]

and im not pulling the heads off again

[Frosted_Monster]

u'll be pullin the heads off after the first day of driving if you built the motor

[89vert]

i know theres a 21st century gas miser sittin in that driveway of yours
This is true


But I've easily got more money into my camaro then my KIA is worth

Actually, I took a year of auto pre-app and spent a few years doing auto repairs. The money sucked and I got tired of doing oil changes and brake jobs, construction paid better and I enjoy working outside. Otherwise I might've stuck with it. So not completely homeschooled

And the LG4 won't be running for many moons yet, unlike chevyman I do ALL my own work, and the real work that pays bills takes up a lot of time. I'm in no rush, I'd rather make sure I wind up with the car I want instead of a halfassed chevyman compromise

[79 Z28]

without calculating it with a flat top and that head cc with the 3.48 stroke you are about 10.4:1 tops

[allpontiacs]

It depends on head gasket thickness and piston to deck height, but with 58cc chambers it could be around 12:1. Which is wayyyy too much for iron heads, even with EFI. The problem is, even if the piston is down in the hole, that makes for terrible quench and it'll detonate like a bastard even with 11:1.

The problem is, even if the piston is down in the hole, that makes for terrible quench and it'll detonate like a bastard even with 11:1.not even close, a 4th gen LT1 is a 54cc head, with a 4.00 bore, .015 in the hole, 4.10" by .040 gasket etc. with a 3.48" stroke and its about 10.2:1 with the oem flat top. my 383 LT1 is a true 12.4:1 with a -5cc flat top piston with a 56cc head, 5 thou in the hole with an impala 0.028 head gasket. but its because of the 3.75" stroke. the only way to get high compression on a 350 is a dome. deck height and gasket thickness will only move it around by 0.2-0.3CR tops with a 3.48" stroke. the more displacement you have the more it affects it.

basically chevyman its a 10:1 motor depending on deck height, gasket thickness etc. if its a flat top piston. run it on premium and it should live.

[allpontiacs]

With 0 deck height, .040 compressed thickness gasket, flat top piston, and .030 overbore he would be just a cunt hair under 12:1. I used a couple different compression calculators

[CamaroRobZ28beer]

CHEVYMAN FTW

[chevyman]

not even close, a 4th gen LT1 is a 54cc head, with a 4.00 bore, .015 in the hole, 4.10" by .040 gasket etc. with a 3.48" stroke and its about 10.2:1 with the oem flat top. my 383 LT1 is a true 12.4:1 with a -5cc flat top piston with a 56cc head, 5 thou in the hole with an impala 0.028 head gasket. but its because of the 3.75" stroke. the only way to get high compression on a 350 is a dome. deck height and gasket thickness will only move it around by 0.2-0.3CR tops with a 3.48" stroke. the more displacement you have the more it affects it.

basically chevyman its a 10:1 motor depending on deck height, gasket thickness etc. if its a flat top piston. run it on premium and it should live.yes i have flat tops, as for deck height im not sure, as for the moron that did my machining, he couldnt even give me a straight answer yesterday..He kept going on about building thousands of engines in his time when I asked him how he calculated 12.5:1..im going to throw this engine through his front window if the machining he did is no good

Ill never go there again

[chevyman]

as for gaskets, im running the fel-pro kit..Thats another thing im pissed about, the last set i bought from lordco was 80 plus tax..

this one i just bought was like 150 and tax...fuckkk

[79 Z28]

With 0 deck height, .040 compressed thickness gasket, flat top piston, and .030 overbore he would be just a cunt hair under 12:1. I used a couple different compression calculatorswith the tightest tolerances (which this wont have) the best i could muster with calcs was a 11:1. thats a LONG way off from 12.5:1. plus thats taking into account everything is spec'd to the hilt. that motor will have so much variance across the board i wont even be funny. id put money those chambers are larger then their rating anyhow which makes this all moot. bottom line is it is safe to say this is not a 12+:1 motor period.

[89vert]

flat tops with valve reliefs and flat tops are not the same

[chevyman]

they have valve reliefs..one all the way across the piston..I posted a pic quite awile ago of the pistons..ill see if i ca find the pic again

[allpontiacs]

In that case it's nowhere near 12.5:1. Valve reliefs eat up a lot of cc's. And who are you to call anybody a moron, anyway? He's doing what you can't even do, so what does that say?


EDIT: valve relief all the way across the piston? Like maybe a dish......dumbass

[79 Z28]

lets just all assume its 8.5:1 without any solid info lol

[allpontiacs]

You know, I really can't believe this clown. He knows as much about cars as my sister yet he's sitting here calling a machinist a moron. He can't even assemble his own motor, and he doesn't bother to get any final assembly specs either. Essentially he has no clue what he's got in spite of paying good money for it, but he's on here blabbing about it anyways, now that's the definition of a moron

[CamaroGirl]

dont fuck with the lordco connection, ya heard
where's my money

snap

And spending days and days of your life trying to make it resemble an iroc somewhat.

Thing that pisses me off is you flame dan dorkson for building flares and his car is worth wayyy more than your junk..pull your dick outta your ass man and realize what your doing.

Just shut up is what im trying to say here man..by the sounds of your bitching it sounds like you haven't been layed in years or ever

Hey, Dont fuck with the LG4!

[chevyman]

lol

[allpontiacs]

Did you just call him "dorkson"? And I've actually been doing the opposite of making it look like an IROC. Reading and comprehension skills evidently eluded you in high school, if you even went to school. I'm not worried about being flamed by you though, I almost enjoy it, it's like drumhawk telling somebody they don't know how to spend money effectively

[chevyman]

your last sentence is definatly quote worthy lol

[Josh_M]

Chevy man, ive got a 350 bored 30 over with flat tops (4 valve reliefs) and 58cc 416 casting heads, and after i calculated my compression ratio (specs of pistons, piston to deck height, gasket compressed etc. etc.) My compression ratio sits Just under 10.5:1...
