Best Engine for Class Rules below, not Drag Racing

Chris Hill · 08-21-2011, 10:24 PM

Given the rules listed below for a truck pull class, what style engine do you think would be the best?

Classic big block Chevy
New style Chevy vortec engine (not sure how different these are from classic big block Chevy
Gen 3 Hemi (not sure if cast iron heads available)
Big LT-1 or LT-4 Chevy
LS style engine (not sure if cast iron heads available)

Thanks in advance. I'm just bored this weekend.
