stroker parts?

[5.0 killer]

im going to best buy tomorrow to buy most of the parts to build my 383 stroker.ive never built one before, wondering if anyone could suggest any parts? what type of crank or pistons?

[stevem]

i used an Eagle crank with Probe pistons.i used my stock rods but put ARP fasteners in them.

[79 Z28]

scat crank, scat rods and SRP pistons for me :)

[93formula]

scat crank, eagle rods and trw pistons. ebay is your friend ;)

[Dunout]

i wana build the same thing what kinda topend should i go with .. and i got an auto so what stall tourq convert would i havce to use ??

[93formula]

the tq convertor will depend on what cam you go with. with top end, ported heads , bigger valves... what motor you got?

[Dunout]

right now i got 350 bored over 40 flat top pistons and a stock topend wana build an engin that will make my 3rd gen caamro go 12 11ish seconds

[93formula]

you wanna pass aircare? is this a l98 efi or carb? daily driven? if you go 11s on a consistant basis, youll need a rollbar. do you wanna hit 12-11s on street tires, drag radials or slicks?

[93formula]

and whats your budget

[CamarofreaK]

ya i want to hit 12s (low 12s) in my 80 Z. right now i got a 350 .30 over flat top pistons 202 160 stock heads 290/300 cam duration its says 465/488 lift, elelbrock intake and carb to . the trani is a stock th350 and 373 gears in the rear. wat u think it would run now on street or slicks and wat u think it would take to get it into the 12s.

[93formula]

which intake and what cfm carb?

[CamarofreaK]

its the EPS intake and i think its a 650 carb

[93formula]

any idea what your CR is? the intake and carb seem fine, the cam im not to familiar with, i take its a hydrolic flat tappet cam. would you have a part number for it. the valve sizing on the heads seem fine enough, are they ported or aluminum? are you using RRs? what kinda exhaust? headers? !cat? h pipe?

[CamarofreaK]

not sure wat my CR is. its a hydrolic cam though. thier just regular heads nothin dont to them yet. i got headers into 2 1/4 duel exaust with 40 series flows that dump befor the rear end

[79 Z28]

that cam spec is advertised duration, some cams that means nothing, cuz thier method of measurement is gay. to truly know a cam you need the spec at .050

[CamarofreaK]

the only other number i got on the card is 1.50 for rocker arm ratio ???

[CamarofreaK]

heres the cam card. i know i know i need to learn how to resize things but i dont so this is how i do it for now :P

sorry homos...needed to make space

[Dunout]

you wanna pass aircare? is this a l98 efi or carb? daily driven? if you go 11s on a consistant basis, youll need a rollbar. do you wanna hit 12-11s on street tires, drag radials or slicks?

both kind of tires. and ya passing aircare would be nice if it can be done and i got a roolbar comeing in the winter

[93formula]

its a 224/234/465/488

with a power band of 2000-4800

kinda weak imo, but its prolly a perfect street cam but the lift is kinda low.

but power is all in the heads, get a set of ported heads and you should see 340ish rwhp im guessing it should do 14s, and you have about 280rwhp the 3.73 gears may be doing you more harm then good with that cam. but then you do have a th350 so jason should be more adept to answer your quarter mile questions.

okay lets say you wanna hit 11s if your putting in a cage, otherwise a cage is useless. and you wanna do it on slicks cause its just easier, lol. now lets say you wanna pass aircare as well, cause we all like to drive our f bodies around.

now to hit 11s on slicks, your also gonna need some safety crap like driveshaft saftey loop, scatter shield blanket thingy. your also gonna want to have your suspension done right so you can launch properly and get a wicked 60 foot. so your gonna want good boxed LCAs, LCA relocation brackets (preferably weld in), sub frame connectors for proper wieght transfer (preferably weld in). if your lowered or going to be lowered your gonna want springs with a progressive rate in the back, and adjustable shocks so you can soften the shock rates at the track, kyb agx is prolly the most affordable , tokicos are in the middle and koni, hals are the priciest.

now depending on what tranny you got your gonna want to beef up the rear, cause breaking rears with slicks isnt fun. you have two choices of the 12 bolt or 9 inch, theres also the gm GN/monte SS 8.5 inch but good luck finding one. then you have to decide which gears, your gonna want a emmisions legal cam so maybe 3.73s is the most your gonna want. 4.10s woudl be nice on a t5 but you have to remember that when your going thru the traps you want to be in 1:1 gear (4th) and not want to shift into 5th.

now if you have the t5, your gonna want to switch to a t56 ;D
some serious 11 second launches on a t5 and your gonna end up breaking it. then you have to decide on clutch, dont go with centerforce, overpriced for what you get. if you do switch to a t56, then i suggest the mcleod clutch disk with lt4 pressure plate for a budget.

now to hit 11s on slicks and manual id say you need a good driver, and about 380-410rwhp. now i dont know what motor you got other then 350, are you gonna be carbed or efi? either way the easiest way for you to hit your goals of 11s and pass aircare would be to add nitrous. run a mild 300rwhp motor and a 100-125 shot of nitrous and your there.

give me some more input on what motor you got and if you want to be able to run this all motor or not.

theres a lot more then doing just the motor to run 11s ;D
ask jason :)

[79 Z28]

lol i know man, chassis and other drivetrain components are just as important. to upgrade my car this year im looking at about 8g over last year ;D

[Dunout]

k im way to poor to do that right now !! lol but its my goal i have a auto its an 700r4 and i got a 350 bord 40over and the topend is stock anything i can do with what i got to make it fast

[93formula]

the most important part is your heads, a top notch quality port job will do wonders for your power band and performance. id say do your top end and exhaust. if you want to stay emmisions legal, i say aim for about 325-350rwhp and shoot a 100 shot of nitrous. that would get you to your goal easily. the suspension stuff you can buy used and get good deals on the net. is yours a tpi? if it is i suggest investing in a miniram intake or a lt1 intake conversion.

[Dunout]

thats what im going to do.. but now i think ill need to chage my torqe converter dont i ??? and what size cam should i go with

[93formula]

your tq convertor will depend on your cam choice and your cam choice will depend on driveablity and emmisions.

[79 Z28]

last year in my 79 Z, i had my 350 with a 230/235 cam at.480 lift, 9:1 comp, 1-5/8 headers, performer rpm intake, 700cfm holley. GM 441 iron heads, 2.02/1.60 valves installed, some exh work etc. flowed 218/211 at .450 lift, 3/4 flowmaster race exh 2.5" dual, a "3000" 10" stall converter that went to about 2800 th350, 4.10 gears, harsh weight reduction, and 28.5x9 slicks. the car was raunchy with that cam, would not pass aircare, unless you detuned like an sob and added like 4 cats :P my best runs were 12.9 @105mph with 1.78 60's a 100 shot would have gotten me maybe a high 11, but it cant pass aircare and gas milage was about 15-17mpg. the only way you'll be able to get it close is your gonna have to step up on the heads, i suggest performer rpms. good bang for the buck.

all in all my motor cost me almost 4g last year to build, it put out 375hp and about 300rwhp in the end. that was good for a 12.9 eventually lol you'll need a good fuel system for nos, and the nos, theres another 1500 at least, gears, stall, tires, etc. your prolly looking at about 6-7g to get her all good to go, aint racing great! ;D

[93formula]

for heads on a SBC i recomend a GM vortec head, then sent off to a american porter.

[Dunout]

i just picked up a set of heads and im able to do them out to a 202 think its worth it there stock 350 heads i think they are 182 cc or something lemmie know

[93formula]

ummm use some puncutation, had to read your post like four times till i figured out what you were saying ;D

stock aluminum heads? or iron? off what year?

[Dunout]

sorry i never use puncutation haha
iron heads and there off a block from the 80ies. thats as much as i know

[CamarofreaK]

thieir stock 194 iron heads late 70s i believe

[93formula]

iron heads= useless for future use

too hard to port etc. get alluminums, get em ported.

[79 Z28]

thieir stock 194 iron heads late 70s i believe
i feel sorry for you ;D buy my 2.02/1.60 441's get a magnaflux for 30 bux or something, if they are no good ill refund your money of what you paid for them :)

[Dunout]

so there is no lose iif i get ur heads tell me more about them ???

[79 Z28]

so there is no lose iif i get ur heads tell me more about them ???
basically worst case scenerio, you lose out on the 30 bux to get them tested, and i have to throw them away. and i give your money back.

they are 441 casting GM heads, swapped up to 2.02/1.60 valves, stock intake ports, masaged exh ports with some porting, they have been flowbenched, and i have the results sheet, peak flow is achieved at .480 lift and its 218/211 cfm they were compared to vortecs in the test. they need new valves, if they are good, cus some are bent from a certian motor problem i had last year :-\

the only reason for testing them is to make sure theres no hidden cracks etc. they look physically fine, but there could be something hidden, better safe then sorry :)

[93formula]

hey jason are these aluminum or iron??

did you port em? they flow close to stock lt1 numbers dont they.

[Mike K]

Jason's heads are good heads but you won't have alot of compression with flattop pistons. But with only 9:1 he went 12.95 so the heads work great for the street/strip.

I went 13.0 with higher compression heads that have zero portwork and smaller valves. The only difference was I had a larger cam and 1 point more compression. With his heads/my cam/my compression I beleive 12.60s are possible.

What am I trying to say? Buy Jason's heads, run lower octane(cheaper gas when you're not racing),and get away with a more streetable cam and everyone will be happy :D

Oh yeah my heads flow 210/135 @ .500 lift :-[ :'(

[Dunout]

how much u want for ur heads ?

[79 Z28]

$175 for you, ultra cheap, get them checked, i think cc racing in richmond can, they do need new valves. they are iron, but make the car really streetable, i got away with running 87 octane with them for low load cruising, and when i raced at the track i used 89 octane. with a 0 deck and a .030 gasket, it will be about 9.1 or so. they have been milled down to about 74cc chambers, i had flat top cheapo TRW cast pistons.
