C9VE, it's a 429, look at the heads and see if they are also c9ve. Looking at the valve reliefs in the piston makes it a 10.6:1 comp ratio. c9ve and d0ve heads were quite popular with the racers as they were easy to make "counterfeit" Cobra Jet heads instead of trying to find the high dollar 429 Cobra Jet heads. I have a 69 429 with the c9ve heads and put in a 460 crank and pistons and made a 466 out of it with a .040 over bore. Edelbrock hi rise, Motorsport roller rockers, Doug Thorley tri-y headers 2.25 intake and 1.75 ex hard seats etc. etc. It has GOBS of torque about 550 ft lbs at 3000 rpm. It will pass anything on the road but a gas station and drinks 93 octane. "OUCH". Have to use the "tall trannys behind em like the 400s and 351 clevelands. It's in a 1986 F-150 supercab with a facory 9 incher.
But I'd rather have a Y-Block!!!!
