which is easier to cool, '77 buick v6 oddfire or '85 chevrolet 4.3 v6....i have both and may put one in '37 willys i have.......do'nt want to cut firewall......charlie
it's against the law to power a '37 Willys with a V-6,you should use a V-8 with about 4-500 horsepower.
I would think that the 4.3 would give a little more bang for the buck. Build it the way you want. jerry
