I've read through all the responses & opinions, even have seen Ed's car run in the past (fun to watch, BTW) & while I generaly agree with most all the responses, the "glaring" problems that seem to catch my eye is wiring & the fuel delivery issue.
Now assuming the valvetrain is all correct & the new gears only amplified an existing problem, we're bac k to fuel issues & wiring. Many enthusiasts add to existing wiring instead of re-engineering their electrical system for the rigors of racing. IF IT WERE ME, I'd find someone I know & respect to go through the entire car to assess its wiring. Sure it can get expense, but a "third eye" might find something you overlooked or simply wasn't familiar with. WE all have our "gurus" in the hobby, but I'd find a veteran, different source, just to ease my mind. Anyway, with that done, I'd first get rid of that red pump (NEVER saw one on a racecar, always blue or another brand), set the pressure to 7-8 psi, as the fuel has to overcome inertia going downtrack, and perhaps consider a carb in the 550-650 range.
Of course don't make ALL the changes at once otherwise you'll never know what cured the problem (besides it's expensive). He's operating his motor in a range alot of strret big-block guys do & they don't have the sort of problem he's describing. My suspicion is the problem is one of assembly & not necessisarily componentry
