454 BBC was idling now won’t hold idle
Hey guys, new to this forum. I’m looking for some help... got a 67 Camaro pro street and increase having a couple issues. Went to test drive it for the first time since buying it over the winter. Car was running decent filled up and drove around car died out would restart (think it was vapour lock) adjusted timing, adjusted valves, checked fuel pressure. Car was idling good but way too high, 1500rpms once clicked into 1st dropped to 1000. Tried adjusting idle to go lower once in gear car would just die out. Left idle at 1500. Let it cool off now it won’t start back up. It cranks over then starts but immediately shuts off. Tried adjust carb but I’m not too sure if I did it right.
Motor is 454 BBC bored out to 496,
Holley dominator 4500 (8896-2)
Msd 7al box
Fuel pressure is about 6-6.5
Anything helps thanks a lot !
