Slow build 71 Scamp 440

Oh yeah. I keep forgetting the open chambers are REALLY open. I used a set of the old 383 heads, found info on the casting number online saying they are 73.5cc. I think you can get eddys with 78cc, if memory serves, Summit said with 78cc I would end up with about 10.29:1, give or take, depending on the gasket and milling. If you want to spend the extra bucks on those the light weight would probably give you a good gain.
