Chevy big and small block engines

[Grant Gatenby]

Sorry if this doesn't pertain entirely to the group but here goes

After a few bits of info here.

Anyone have any idea what the weight of a 350 SB as compared to a 427/454 
BB is ?? and then the same with alloy heads.

Next question. what is the ideal EFI setup....stock TPI or a manifold with 
one throttle body per cylinder, or just a modified Corvette TPI 
setup...maybe aftermarket computer, bearing in mind also we may be looking 
at methanol also

The end result has to be a dirt track engine producing around 500-600hp 
from as little capacity as possible with a maximum of 434ci
