Figuring out how much heads have been cut?
If it's really 7.5:1, I guess it's time for a turbo!!
I was told they were TRW 10:1 flat tops.
I'm kind of thinking they just tossed whatever parts they had together.
It's a 69 block from a Newport with LY rods, the trans was a 73 727 from a Charger with a 3600 stall converter, the heads are 915s, the water pump housing was a 1964 or 65 one year only version with a M1 intake. The cam was a Crane 312, which is WAY to big for low compression and stock heads and the exhaust is 2 1/8" pro parts, also way to big.
But, whatever, it runs great and sounds even better!
Now it has a 833, and a Comp 274x grind cam. A little more street friendly, which is why I wanted the dual plane intake, that doesn't fit...
