Barry here has a VERY nicely restored 1982 Crossfire Corvette running a 1227747 computer system to allow programming for a little stronger engine.  Retaining the crossfire setup has proven to be a little restrictive on the engine but still vastly outperforms stock.

Motor consists of a nice 383 stroker kit yielding 10.5:1 compression with a set of procomp 190cc aluminum heads and a comp cams 12-466-8 retro roller cam with 218/224 duration @ .050″ and .570/.565 lift with matching comp cams magnum 1.6 roller rockers.

As you can see it pulled 245hp and 322lbs of torque at the rear wheels (310hp 400lbs torque at flywheel) which may not sound like much but you have to look at the graph and see that the motor pulled that 245hp by 4600 rpms and the motor was really getting restricted by about 4100 rpms.  If you look at the graph for my www.tpichips.com/lt1rs.htm project you will see by that 4100 rpms that his engine was making pretty close to the same power as my LT1 and I think a little more compression and an electric fan and it could have pulled the same number there as my car as both projects are running almost the exact same cam specs.  Difference is the intakes.  The LT1 uses a good single plane intake design that is proven to make good power and Barry just couldn’t get that crossfire intake to flow enough air to keep up with that engine.  But with that strong low end that car is much quicker than those numbers would indicate.  With corvettes its hard to find a intake setup that will fit under that hood and Barrys vette is a nice stock looking car that runs far stronger than a stock crossfire corvette. Sometimes you have to sacrifice a little power to maintain the look of a nice classic.  That engine just like my LT1 car should be capable of pulling as much horsepower as torque with the right intake/throttle body setup and that cam in a 383 should peak around 6000 rpms just like my car did.  TPI cars have similar issues with the power dying around that 4500 rpm mark for the same reasons.
