[jboy]

well, got the car ready for the road, putting insurance on it tomorrow and will be driving it daily by mid week,,, a four year labour of spewing endless amounts of cash frustration planning searching swearing cursing bitching and finally it's all done. the car has been on the road over the last four years but i bet i could count the amount of times i drove it on one hand.lol
I'll get pics put up by the end of the week :D

awesome

[TA_GTA]

Sounds pretty nice

[allpontiacs]

Is this the one with the Olds motor???

[jboy]

Is this the one with the Olds motor???

:D :D
yep 455 Olds performer II Intake, not quite a full cam, Hooker Headers and true Dual exhaust,,,never dyno'd guessing maybe 300 HP and prolly 400 Lbs of torque
7.5 to 1 Compression
stock rods connectors and valve train,,, i know you know what this motor is begging for?? 97cc Heads? what would you suggest??
Between you and Jason you guys could probably get me goin in the right direction,, i was thinking it'd be a good motor for either nitrous or a supercharger,, which i don't know much about either ::)

[Bacon604]

sweet :D

[allpontiacs]

Stock rods and pistons wouldn't hold up to forced induction, even though the compression ratio is ready for it. At 7.5:1 you're losing out big time, though. I'm not totally on the up and up on Olds motors, if you had a Poncho it would be the complete opposite. Speaking of which...the car IS a Pontiac...Pontiac motors are great...hint hint. I'd guess a little bit lower on the power scale, though. At any rate, the best thing you can do at this point is find out about Olds heads. I've heard a rumour that a lot of small block Olds heads will give you a decent bump in compression on a 455. Find out if they're closed or open chamber, too, another great idea would be to get closed chamber heads and zero the piston to deck height. At that point you should be able to find a factory head that can give you around 9.5:1 (you don't want to go much higher than that on pump gas unless you switch to alu heads). Better internals, a bigger cam (oh stock valvetrain would be a no-no here), and more compression would really wake that motor up. I'm guessing it was a 403 car?

heads.cam, intake that beast

it was a 301 non turbo,,but ya if i could get heads off a 69 Toronado(97cc per chamber) with a 455 in it,shave them, zero pistons to deck, i think it would give me 9:5 to 1, and i prefer higher compression and remaining N/A as the higher compression draws more volume,for compression and combustion,and in a big block it's more than enough ,which i think i would be happy with that,, but it's the bottom end that scare's me, i don't want to throw a rod, or spin crank bearings ,lol
and fuck ya i wish i had a 455 Poncho,,but i ain't that lucky for right now, but if i had the Poncho i'd go to the bank borrow 10 grand ship the motor to a builder i know and get it back 3 months later with about 650HP and 550TQ,,,the guy is basically a good friend and would charge me half the shop rate,,so what would really cost 18 grand full retail would cost me about 10 g's,,,fuck i wish!! :drool:

[allpontiacs]

Just out of curiousity, what was the reasoning behind going from a Pontiac to an Olds motor? I would think that's more hassle than it's worth, especially with P400's still being fairly common and cheap (not to mention very easy to build, you can get a solid 300hp at the crank out of an 87 octane 400 that is both reliable and fairly cheap to build). At any rate, keep the Olds on 87 octane and the bottom end would hold up fine, although I'm not sure why you'd want it to. It sounds awfully stock-ish. At the very least, zeroing the block is always a good idea.

[jboy]

very stock and very tame at 7.5 to 1, lol,, but ya the 301 that was in there was done and the big block in running condition cost me 900 bucks, so i went for it and had a cam and intake put on with some headers,, basically to get the potential out of this motor i'd have to go through the whole bottom end get decent heads and valve train,,,from what i can figure out,lol,, also i like the 400's and if the 455 detonate's one day i'll be looking for a 455 Pontiac or 400,,and i'd like to go 4 speed,,the 455 Olds in there now won't bolt up to a 4 speed without changing the whole crank,,and i'm not into it right now,,,no shop,,minimal knowledge and little cash,lol

[66chevyIISS]

Not to burst on your bubble or anything but that engine is probably barely making over 225hp with that compression. The Pontiac 455 in 76 made 200hp with 7.6:1 compression. I am sure the oldsmobile is similar. Your intake, headers and "full cam"(whatever that means) isn't worth 100hp. sorry.

[jboy]

3/4 cam or "full cam" is what i meant and it's not too aggresive of a cam that's in there,, i can't find the stats on lift and duration for the cam,,i didn't go to aggresive as it was no point with the stock heads,,but ya it's never been dyno'd so it may not be 300 HP,,i'm just guessing,, i enjoy my car for what it is,200 hp 250 hp or 260hp,it's still a thrill to drive with that much torque,,you know,big block torque, so no worries no bubble's bursted here,lets say it's 250 HP max,,, no problem, the main reason for the big block was potential,,,i don't consider a performer intake cam and headers a complete build up,,,but when i do go Ape on the motor and have it built to what i want it to be i'll definately post some Dyno slips,,,
That's nice car you got there, do you have any stats on Torque and Horsepower for that monster? i think i saw in other posts that it's a stroker? post up some dyno's if ya got em so we can have a looksy,i like all kinds of Muscle cars. :)

[66chevyIISS]

I'd love to see pictures of your car, I am sure its very nice! I wasn't trying to slam you in anyway, just trying to show a litte more reality to the horsepower claims. As far as the 3/4 race cam comments etc.. I would shy away from the terms personally. That was something they used to say back in the 60's and 70's when there was only a couple of cams they had to choose from. Those terms don't really make sense anymore with the 100,000's cam grinds out there. There isn't really a "race cam" or a "half race cam" etc.. :D

Anyways... a 455 is awesome and has great potential if/when you ever go that route so thats cool you did the swap.

I will send you a pm about my car so I don't fugger up your thread anymore! haha its about your car not mine!

[jboy]

ha ha,,for sure,, i actually got complete pics of the tear down and build up but the pics are 265 kb and the site won't let me post anything over 100kb,,so being the dummy computer guy i am i haven't figured it out yet,lol,, and yeah man i'm from the 70's so that's where the old school sayings come from,,i definately have a lot of catching up to do,, lol,, i figure just from the guys on this site there's a ton of knowledge and when i get to know people better maybe i can hook up with someone and do some wrenching,, i got most of the tools but got very basic skills at best,,hah ha,, but a healthy appetite to learn more,,especiall on the kind of cars we drive,,i love em,, looking forward to your pm and details on your ride
:)

[jboy]

66chevyIISS,,, i sent you pics to your hotmail,,, i can't figure out how to host them here,,lol

[allpontiacs]

Too bad you live out in Delta, I'm always up for some 2nd gen Poncho wrenching.

[66chevyIISS]

66chevyIISS,,, i sent you pics to your hotmail,,, i can't figure out how to host them here,,lol


I never got them? hmmm try to resend them

[jboy]

ya Delta's kinda far from everything, but i got access to a car trailer so i can haul it around if it had to sit for a few days or i would drive the TA if it wasn't a huge job being done and could be dealt with the same day,lol,,

ChevyIISS, i sent them again and then i sent an email with less pics in it so maybe that'll work?
lemme know
:)

[66chevyIISS]

they both finally came through for me. just took forever.

Delta is the closest thing in Canada to me haha.

[66chevyIISS]

and some more pics of his car. Looks good! I love those hoods.

[allpontiacs]

Nice car, man! Nice covers, too, I've got a set of those finned M/T's for my Poncho. They look wicked when you paint them and then sand the fins. But Chevy orange???? Argh! Anyways, to be honest I think you've got the wrong intake combo going there. Is that a Performer RPM? Kind of looks like it...at any rate, there are better intakes for your combo out there, and I'm sure that Q-Jet needs some work to actually match the intakes potential. However, if you upped the compression, got some porting action done, and put a bigger cam in it, that intake would be the perfect thing. Maybe with a square bore 750 v/s on it.

[79 Z28]

nice car man

[jboy]

tks Jason,
Allpontiacs; yes it's performer II and ya that Qjet is a 750 and if i knew how to zero the pistons, and dial in the carb i think the intake would work better,,if i could get the compression up to draw in more volume,then free up and tune that qjet i'm sure the intake would be more usefull and it would be way way better,, :(
fuck, no shop, and scared to try it myself,,

[allpontiacs]

Well zeroing the deck means ripping it down to a short block and shooting it off to the machine shop. It costs money and is usually done when the engine is rebuilt with quality bottom end components. Power and reliability is never cheap...the Q shouldn't be a 750, I think most were rated somewhere around 680-700cfm? Something like that. Some were 800cfm. Either way, they usually need a lot of work to be a performance carb, although when they get that work they often outdo equivalent "high performance" carbs and give way better fuel economy to boot. If you plan to keep that engine, this is what I would do; get the crank magged and resurfaced if needed. Get forged H-beam rods. Get forged pistons. Get the block tanked, magged, sonic-checked, then fill it and bore it as far as you can. Stud the mains and have them line bored. Have the rotating assembly balanced and then get the deck zeroed. Get good aftermarket alu heads with roller rockers that will give you around 10.5:1 compression when all is said and done. Get a solid cam, with specs somewhere around 220-240 intake/225-250 exhaust (all .050 duration) on a 112LSA (lift isn't a huge issue, whatever you can find in that range will do). Keep your intake and put something like a 750DP or 850v/s on it. Keep your headers. Get a nitrous kit. N/A that combo should make around 500hp off the bottle and more depending on how much you spray it, and it will be reliable and run pump gas to boot.

[jboy]

bout 7 grand?

[79 Z28]

95% of q jets had the ability to flow 750cfm of air.

on a side note, jboy, you still interested in the posi? :D

[jboy]

Jason, definately! will have the cash on Wednesday next week,
tks for hanging on to it

[allpontiacs]

Probably around 7-8G's if you put it all together yourself. And it would be the longest lasting part of your car, so long as it got treated right in the beginning. Of course, you could always still put a Poncho in it...like I say, I've got the foolproof 300hp 87 octane 400 buildup that's bulletproof and wouldn't cost more than 2-4G's. And there's everything in between.

[79 Z28]
