77, I am rather confident that a cam in that wagon would be a non-starter.
Interesting thread on the Buick 350 here:

I had no idea that the Buick was significantly lighter & had more torque that a comparable Poncho 350.
Of course the Buick is a much newer design and was meant to be smaller.than a "big block" Pontiac.
