If there stock type pistons I think its fine, if there zero decked so they don't have do offset crank would a bit of a compromise if domed that would be slightly cheating.
This is just what i think it should be. We all have are own thoughts on it. some vary passionate.
It should be what you could get in that time frame, but break the rules, a little, with today tech. Such As, small stem LS valve.....that's ok, grind crank to stroke (sort of) it... that's OK........they were doing that in the day. Lighter piston of today......they have to be replaces sooooo OK. Grinding on the rod, over a much cheaper lighter and stronger rod???? Well, that is what they would have done in the day.
Using a 340/360 head????/ i say NO! with the 4 barrel Intake YES! It was available in 72. ( I personally think that they should use the 72 and older head and intakes) Not because the 302 head is aka a I/M head but because it hadn't been designed in 72) Exhaust manifolds????? you could get header for them back in the day......but once again......not with the 2 barrel.
OK, there is my 2 Point-five sense worth of a opinion. :elmer: :lol:
