67FordKC; My book does not show a 352 made in 1967.
It only shows the 352 going too 1966.
1964 had the highest compression rating at 10.5 to 1
and that was on a factory 4V.
I don't show any HP rating for the 352's in my book which is odd.
I am guessing but I would say that it is around 300 HP.
A 390 with 10.5 to 1 is at 315 HP. just to give you an idea.
I hope this helps if you know what your compression was we could get a better idea.
