for the past year or so my 38 ford has been choking on wide open throttle. It has a crate 350 sbc, unsure of the specs. Has a turbo 350 in it. It Falls on its face. Let off and it regathers itself. Pulls hard with a normal foot. PUZZLED!!!! Things done so far: Put in new mechanical fuel pump. Pump was reading before 2-6 lbs. new one at 6lbs. Replaced old accel dist with a summit ready to run and then to a msd ready to run. All vac advance. Replaced spark plug wires. Replaced spark plugs Replaced 1406 edelbrock carb with avs 650 edelbrock. Vacuum at 16lbs. Added inline fuel filter Blew out fuel line Checked inside tank and it’s clean, almost new. After replacing the carb, it performs drastically better that it did before with the old carb. Missing something....... please share thoughts.
