I have a 20 over 360 with 9.5 comp., worked edelbrock heads, M1 intake, TTI headers and 1.6 rockers. I have a 650 DP on it now and it runs mid 12's. I put my buddies 750 DP on it and it ran 12 0's and has went high 11's a few times. A friend has a 850 DP I can get for $100. Is this too much carb for my combo?
