SOHC

4.375 x 4.375, Dove heads ported, custom grind cams, 750 lift 334 duration, 306 @ .050, splits with tunnel ram, MSD crank trigger, Ford reworked dizzy by Joe Panek, 14:1 comp. Original Ford non adjustable rockers, never gave me any trouble. No trouble with the ignition, has the steadiest timing I've ever had. Dyno operator said he's seen a double peak HP many times???

Vacumn was 12 1/2 to 15. Jay's vacumn leaks are probably at his dizzy, ask me how I know this. I do have a couple of other pulls a few HP over 890, but none in 900.

I might pull the motor down next year to freshen it and redyno it at a different facility, RWJ
