Alright so I just got an email back from Dave of the SCCA, and he says there are no age limitations anymore for pro/club rally in the USA.
He also says any mopar/chrysler or AMC engine will do, so long as it's under 5.1 L with a multiplier of .8 . That gives me about 389 cubic inches to play with.
Any suggestions for a v8 that's small in size and big in power? I had my eye on a Dodge 325 hemi...just so i could say Hemi...but they're big in size and weight. Remember, it's gotta go under the eagle hood.
I think i found my next car.
