Thanks, it was a pretty nasty motor, my brother built in in the late 70s, had the 4V heads, 11 to 1 pistons, 4.11 gears, I don't remember the cam specs, but it was stout. I eventually swapped out the cam for a milder one because it was just too radical for the gas that was available, still ran very strong, never took that one to the track, but I never lost on the street with it, would pull 7000 rpm easy.
