502 RamJet Tuning issues!

[AMERICANMUSL]

Hoping someone can help me here. My Uncle and I both have 55 Chev's; his is a dily driver Bel Air 2 dr ht with 502 RamJet hooked to a worked Th 400 and Speedway rear end. The car is a frame up,Retro-Restore mostly by DP Chevy. After 2 years(to be 6 months turnkey), DP replaced altenator and Arizona/Speed and Marine computer to alleviate a terrible stumbling/stalling problem upon quick, hard accell/decell of the throttle i.e. reving the engine. This also occurs from idle to anyspeed. It's the action of the throttle which dictates the problem. DP washed their hands of it, GM won't have anything to do with it(this is there crate motor)whacked:. Substantial money and time has gone into this Rod so I am looking for alike stories, advice or better, a specialist in the Riverside, Orange, San Diego or LA County area.

Computer has already gone through 500+ mile relearn.

Thanx in advance

sounds to me like its squirting too much fuel too fast.... your injectors could be too big, or your computer is telling it to give too big of a squirt.... i could probably figure it out in a matter of minutes with a tech 2..... those 502s are also notorious for fouling plugs
