Default What to do? New engine time

Replacing the stock shortblock, heads and cam.

I will keep the Fast 90, and the ASP pulley. That's about it. This will run through a TH350, 4600 stall, CM DS, 12 bolt and 4.10 gear. I want a combination that will shift out at 7000 - 7200 RPM.

My idea of driveability is not killing the car between the waterbox and the trailer. I will see about 2000 street miles a year.

Combination I am tinking about:

1. 348 forged 12:1 big cam ETP 225 heads

2. 370 LS2 block 11.5:1 big cam ETP 245 heads

3. 370 Iron block big cam 11.5:1 ETP 245 heads

No strokers. I want to run 10.7 or better every time out. The car has about .2 left in it from the 11.30. I am learning to drive after the TH350 swap. Gotta remember there is no clutch to break anymore

I would think with those heads, a BIG cam & the FAST 90 more cubes would be better. And since I've never been a fan of sleeved motors in hi compression or boosted applications, I say go with the iron block.

LOL at you idea of drivability

If its a basicly a track only car why not build a high compression race gas motor?

Ordered a 347 from Speed Inc. 13:1 compression and a big *** cam. Should be fun. Now the weight reduction starts.
