I'd keep the compression down so I didn't have to use a long cam which would lead to the expense of a looser converter, insufficient manifold vacuum, yada, yada, yada. Even though they are a thin casting, prone to cracking and require a dedicated intake manifold, I still think the Chevy Vortecs are the best bang for the buck. Just don't get 'em hot!!!!

I'd bore it 0.030" and use KB hypereutectics hung on 5.7" Chevy rods. Static compression ratio would be 9.0:1. I'd zero deck the block and use a 0.039" gasket for good squish with regular pump gas. I'd keep the cam short for good torque, ability to use a stock converter and keep costs down, build good manifold vacuum to operate accessories. Another reason for a short cam with Vortec heads is that unless they are modified for higher lift at further expense, they are limited to lift at the valve of about 0.450".
