I just bought my Rogers last summer I only had it out a few times due to rusty fuel tanks plugging the fuel filter. What kind of mph and HP are you guys running. I was spinning an A to 4700 with a very mild olds. 461 9.55:1 stock heads with large valves for an olds offenhauser tunnel ram with 2 660 center squirters and log manifolds. The only change is the addition of headers and roller rockers
