It's a 360 about 9.5:1, zero deck flat top pistons with closed chamber ported Edelbrock heads and 1.6 roller rockers. M1 single plane with a worked Holly 750 double pumper. TTI headers and a 3500 stall. 430 gears. 28" tire. It still needs some tuning and I'm learning as I go. What a blast, if I had known it was this fun I would have started 25 years ago!
