If I had to do it all over again when I got my 2.8 I would now save up and do the following:


Pull the engine
Have the heads and block hot tanked
Bore it 40 over not 30, but 40
Shave the heads 1/1000th
Gasket match the heads and intake and exhaust manifold
Add the coyles double roller
The Crane 2030 Cam
1.52 roller tip rockers
Assemble

50 shot of nitrous and 3.73 gears and dynomax cat back. I would keep the 2.8 just because I like matching numbers and stuff.

 

I dont think any of that would help very much without headers. (exept for the nitrous)

 

If I had it all to do over again?

Buy a TIG, plasma cutter, and mandrel bender.


Seriously? 3.4, forged 8:1 pistons, forged Chevy 5.7" rods, nitrided/polished crankshaft, running on a T66 single turbo setup, with a Profec B, all on a custom roller cam + roller rockers.

Hey, that's just me, though. Oh yeah, Bow Tie block, Al FWD heads, custom intake, and a G-Force beefed T5 pushing the power through a new set of 315/35/17s - Fikse F/5s - as well as a full Spohn suspension setup... :hail:

 

Amen to that Doward

 

Quick question, maybe you know. Why won't aluminum heads work on our cars? Is it just the 28cc chambers (as opposed to our 50cc iron heads) or is the intake runners a different shape leading from the transverse intake manifolds? If its just the cc size, heck, I'm building the bottom end from scratch.

 

www.60degreev6.com knows ALOT about this subject.

There are like 4 different aluminum heads, the splayed valve ones fit pefectly, but all the others (3400, DOHC, etc) require some modding to get to work. The biggest problem with putting FWD heads in a RWD car is that the intake will be backwards.

 

I'm not talking about the overhead cam heads at all, I know those won't work. But the gen 2 and gen 3 aluminum heads should. What I am really asking is- Do they have to be used with the gen2 and gen3 intakes? If so, then yes the intake will be reversed. Otherwise our intake, if lines up, would be correct. Will a MPFI lower(base) intake line up on the gen2 or gen3 heads intake port shapes?
