340 Build.

Maybe it's just me, but it seems the "bigger is better" mentality is alive and well. You could run deep into the 12's with 9.5:1 CR, pocket ported 2.02 heads, a 220-224 @.050 cam and 1.6 roller rockers, an air gap manifold with a 750 carb, 1-5/8 headers, and a 4.10 gear. A little tuning ability will also be a plus, engine and chassis. Oh yeah, it won't sound as mean. There's always a compromise somewhere.
