I am lookin for Ideas from the hot rodders. I am running a 10.1 compression 30over 390 with a very large cam. If I run her easy she romps hard when I get on it with no noise but if I am in it a few times she starts to ping on accell. I have tries 101 octane fuel and retarded the pee pee out of the timing with no success. I am also running all eddelbrock intake, carb and a 110gph fuel pump so I know she is getting fuel. Ideas Please!!!
