so whats the ?
you know how to build an engine, low12's high 11's are not hard on that plateform thats basicly unchanged for 30 years..
g bodys are not heavy.. my SS is 3300lb and it's loaded..
a stripped malbu should be 3100 or less..
I'd think a low rpm(relative) n/a 355 or a s/c 355/383 would be able to go the whole season with nothing more than valve springs..
or, cheat and build a rock solid lower end and spray your way to glory..
