I just got an E 303 cam, Edelbrock upper and lower, 1.6 rockers, heavier springs, 70mm accu fab TB installed. Now all the sudden once the car is warmed up and I’m either down shifting from 2nd into first (slowing down to stop or turn) and the car gets to under 1K RpMs with the clutch engaged it just plummets and stalls out. It’ll start back up but it’ll only stay started with me feathering the pedal. Anything higher than 1K and while I’m driving I notice no changes , also while it’s warming up at idle it seems fine, this only happens after it’s warm and I’ve checked for vacuum leaks already and can’t find one as of yet but did find this piece laying in the engine bay next to the brake cylinder.
