Engine pinging? what to do??

The cam is advanced 4 degree's and the cranking compression is in line.

No, I don't do any low rpm cruising. There is alway's one of my feet on the floor board! :lol: This motor may have 500 miles on it or so. My plugs look good so I doubt it is carbon.

If I get to the point of running straight race fuel then I'm gonna make her a race motor. I think I might just buy Indy D1's and push about 600 Hp, then I wouldn't feel so bad running $3.50 race fuel. I kept the motor sort of de tuned so I could run pump gas. Seems as if that ain't gonna work. A 600+ HP small block would be cool though :thumrigh:
