I think a 400 bored .60 with a 440 crank will produce what your looking for. I believe that you have to grind for crank clarence.

I have a 65 ply satellite - do you have any idea what it weighs with dana, ladder bars, row bar, 727 and aluminum big block. Glass hood and front racing seats. No other fiberglass on car.

My thoughts were around 3500lbs based on talking with others. How did you get your car so light?
