hey in a earlier post someone told me that i needed to replace my heads and intake manifolds before i could get any real power i would love to do that but i need to know what kind and how much and how hard are they to replace myself any replies would be great

 

You need the heads, valve covers, intake manifold, and gasket set from a "W" car 3400 or 3500 engine (3500 breathe better), also get the roller rockers that come with those engines. The heads are a direct swap, the intake manifold will need to be turned so that the inlet is at the front of the egine. The roller cam that comes with these engines will not work in the Camaro block, so you will need a pretty hot flat tappet cam to take advantage of the new heads. The compression will run around 13:1 unless you change pistons. You will also need exhaust manifolds or headers as the ones on these engines aren't compatible to the way the engine is mounted. after it is all done, the PCM will need to be tuned for the new set up.

 

The one guy I know who has done it, Russell, dynoed at 216hp/250TQ at the flywheel, which is about 184hp/212tq...at the wheels.

Not too bad, even with no real good way to tune the car just yet...

You've seen the links in the stickies....so you know where to look this up.

 

hey thanks guys umm how muchg is this stuff gonna cost for the whole thing like everything z28pete listed and how much horsepower am i lookin at is that, that 187hp u said cuase that sems like alot of work for like 30 horses i dunno and also if im gonna change all this out from the diff car engine wouldnt it just make more sense to buy performance parts off the bat let me know

 

he was talking 184rwhp thats a lot different than hp. Hp is what is rated at the crank but rwhp is whats at the wheels. So his 184rwhp is 216hp. The 3.4 had 160hp at the flywheel and 140ish rwhp. In his setup he said he took his friend who owns a 94 z28 convert. And for that kind of work I remember reading somewhere that its about 2 grand or something like that correct me if I am wrong.

 

thanks for the numbers so 216 thats not bad do u think after those upgrades anda cold air intake id be able to run with v8s just wondering and i asked earleir about wat about changing all the parts for performance or is that wat i need to do



adam

 

hmmm, LOL... after engine upgrade then maybe you lose alittle weight around your car if you know what I mean

 

216hp is also with a lot of mods. You have to have some of them such as the headers for it to even work. But really you are just putting on newer Stock parts. He has the same compression as the pontiac and with the increased engine size the power would be about 175hp if it were stock but you have to have a few mods for it to work and alsong with those a few he had on it gave him the 200. He had the 200 until he changed his cam and a few other things and that gave him the 216. The 200/216 is from the 3100 heads and intake from a 96 pontiac. I dont know his current setup with the 3400 parts from a newer 1999+ car. Thats the setup that he beat a z28. Because 216hp is not enough with the weight of our cars.
He has not dynoed that setup yet or atleast has not posted it.

I am only stating what I have read I have not done the swap or talked to anyone that has.

 

im so sorry espesially if this is gettting anoying all these questions but i dont know that much so what car do i want to order parts from for my car can u give me all the specs so i can know thanks

 

You can probably get the parts at a salvage yard and rebuild the heads. You are looking for parts for a 3400 or 3500 engine that cames in front drive W car. The 3500 heads and manifold breathe better than the 3400's. You really need the whole top end of the engine. The cam in the Camaro engine is too small for this set up, so you will have to get a pretty hot flat tappet cam. Can't use roller lifters in the Camaro block.
