I'll plug in the numbers from my last post and see what we come up with.
400 + .030 bore, 90cc chambers, 6.7cc valve reliefs, .036 x 4.160 Cometic head gaskets, and .005 deck height CR = 8.86
So, this combo with either the 262 or 256 Voodoo cam should make well over 300hp AND be pump gas friendly.
This engine combo with the 262 cam and a stall converter with a TRUE stall speed of 2600, and the lower 1st gear ratio of the 2004R tranny, should make for a spunky launch, or a lot of tire smoke, depending on traction.
For another couple of hundred bucks or so, you can go with lighter, Auto-Tec brand pistons and H-beam rods. This will make the rotating assembly lighter, which will free up some hp, and allow the engine to turn higher rpm safely. The valve relief volume is lower, @ 3.8cc , since they have only 2, instead four, as on the SP pistons. So that will increase CR slightly, also.
