327 swap in a 84 sc
Hey guys, Im thinking of throwing a motor in a roller that I had bought for parts. Its a completely spotless 84 Camaro Sport coupe. The can has manual locks, windows and manual steering. The entire interior has been stripped to put in a formula. All that left are a dash with no hvac stuff and door panels. I would like to throw in a moly cage and a seat and get my wife out on the track. I currently have a small journal 327 and a th350 just sitting in the garage. I also have a 3500 9"stall laying around. Im going to just guess and say that the engine is around 300 hp because im not sure what it came from. What do you suppose that it would run bone stock till I can afford to build it all for her next season. Stripped 84 sport coupe110 girl327th350 3.73 10 bolt on sticky tires.

Plans for the car are to go .040 over 350 pictons on a 6.125 rod with stock crank. AFR 190 competetion CNC heads. Close to 13-1 compression. Big roller cam and spin it to 8500rpm. Th350 with brake and a 6ish stall.9" rear and paint it furious fuscia the mopar color.

Re: 327 swap in a 84 sc
Should be a very light car, I had a Berlinetta with power windows and locks and more interior and it weighed 3050. Obviously the cage is going to add some weight.

Re: 327 swap in a 84 sc
Im hoping my formula weights in at the 3000-3100 area. Hopefully I can get this camaro down to the 2700 area. She should yank a my wifes *** even with 400ish hp.

Re: 327 swap in a 84 sc
On my 82 Berlinetta, I made it down to aluminum heads, 15" weld pro stars with skinny fronts, no heater, plastic summit seats, no carpet, limited interior, fiberglass cowl, etc. It was a "street" car, at least that's what I wanted it to be.
It always seemed like about the time I had gotten the car really light, I would do something that added a bunch of weight like a roll cage lol.
I sold that car some time ago and bought an 89 Iroc Z. I think I shaved probably 300+ pounds off the thing in the first week I owned it. The person before me built a custom plywood box with a 12" sub, amp, monster wire, etc. That alone probably weighed 150 pounds. At the same time I got rid of the spare tire and jack, all AC equipment and all smog equipment.
I just took it through the scales and it is sitting at 3300 pounds without driver. The next thing I want to do is swap the power seats for summit seats as the stock power seats supposedly weigh 55 pounds a piece
How much lighter is the aftermarket hatch over stock?

Re: 327 swap in a 84 sc
If you go to a rack and pinion setup, everything in front of the strut towers can be cut off (given the appropriate heading is in place). Just build a custom rad support and some stuff to bolt the front end to. That's the only way I see it getting to 2700lbs

Do you have any idea how much a setup like that runs?

Re: 327 swap in a 84 sc
i got auto corrected, where it says *heading* it's supposed to be *bracing*
cost is relative. check out some different companies and look at what it'll cost. spohn, bmr, racecraft, pa racing, aje racing, lots of places offer tubular k-member with rack and pinion options.

Re: 327 swap in a 84 sc
I jumped into the engine and found out a few things about it today. What we were told was a free possible fresh 327 is not, it is actually a
60's 350
.020" overbore
Wisco dome pistons
Atleast arp rod bols,cant tell if rods are stock
Arp mainstuds
Forged crank
041 fuelie heads
Ported
2.02 valves
Double valve springs
Comp push rods
Screw in studs
Guide plates
New cam and lifters(no clue on size, guess not stock for sureh
.015" shim headgaskets
1.6" Harland sharp roller rockers
The engine is completely fresh, like never fired. Imagine the look on our faces lifting the valve cover to see those new shinet rockers haha. What do you think it will run with this engine over the 327? Also what is a safe rpm toturn it to and what intake should we look for?

Re: 327 swap in a 84 sc
I picked up a Weiand Single plane today and a msd pro billet to drop in it. I sure hope I can touch mid/bottom 12s.
Would a 4.10 gear be better than the 3.73?
How many rpm would you guys spin this motor?

Re: 327 swap in a 84 sc
If I pull the timing cover and gear will I be able to identify the cam by the numbers on the end?

Re: 327 swap in a 84 sc
There on the end with the chain. The cam is comp cams 300b6. That number brings up the specs of 264/270 .630"/.630" on a 106 lsa at .050". Bigggg cam.. What kind of power and times and rpm are you thinking?

Re: 327 swap in a 84 sc
The cam is way to big for the heads in my opinion. You will probably hurt power with that big of a cam if those specs are correct. Also a ton of duration so your going to have to spin it high to make power which your setup probably wont like.

Re: 327 swap in a 84 sc
Why go down on the cam? If those heads have been ported by someone that knows, they could very well flow decent. That motor should make at least 550 hp, maybe more. If it's got good rods, it'll make power to 6800 or so. I'm going to guess it'll run bottom 11s or better. I'd go with a better converter though, 5000 or so. Feed it some E85, it'll like it.

Re: 327 swap in a 84 sc
Have you verified the crank stroke to determine if it's a 327, 350, or 383 yet? A lot of guys get hung up on this "it takes a 327 to rev" myth and will intentionally do something silly like destroke a 350 and throw a giant cam in it. Hell it might even be a 302. The bigger it is the more likely it is that cam is costing you power so it's worth finding out. But you said you know the crank is forged, so maybe you ran the numbers and found out it was a 350 for sure. 4200-7200 power band according to comp. Those are some pretty intense numbers... That's a tall order for some old school ported factory castings. After you get it to the track it'll probably be al ot easier to tell if you're leaving anything on the table though.

Re: 327 swap in a 84 sc
I was guessing it on it being a 383. I'll still say mid 11s, like you're thinking. My 383 ran 6.40 1/8s pretty consistantly in a 2850 lb. car with less cam and a little better head, on 100 octane fuel. Is the cam degreed in to comp specs? If the motor has factory rods, I'd change them out even if they do have good bolts. I've seen Eagle SIR rods bent double and not broke, matter fact I have one in my garage. Had a crankshaft break a few years ago.
