Pump gas compression

Well said Skews.

6pkScamp, tell us about what type of combo you are wanting to run.

I myself have run a set of KB-107's @ 0 deck with 72cc J heads and Edelbrock heads @ 63cc. Cams have never been smaller than 244*@.050 with a 4spd manual & 4.10's. no pump gas problems at all. So depending on the head flow, the J's being the worst, I could still get into the 12's easy enough. It makes for a great street car.

It will be street/strip but not a cruiser. Not concerned about street manners, it may go to town for a car show otherwise I just take it out thash her and put it away. The indys have a 62cc chamber so I need to decide on a cam. The block is at the shop now getting decked so I dont know where that will wind up. Just took the four speed out put in a 727 with Dynamic 9.5 convertor and either 410s for street 456 for a trip to the track. The weight with the old motor was 3400 with me and 2/3 tank of fuel.
