I swap a 350 into my trans am and I'm having troubles with my carb ( edelbrock 750 cfm) because it's spitting out gas and I don't know why is that happening. My family and I built that engine, it has 305 heads, crane camshaft with 275 deg, edelbrock 750 cfm and it has a 180 psi compression.
If anyone has a clue please tell me

 

It's because it needs rebuilt. The needle and seat is bad, or has trash in it, or it's sticking.

 

thanx, I'll let you know if I get lucky
