I have recently done a crossfire injection to carburetor conversion on my 1983 Camaro. It would start and idle real good and then the ignition switch went. I just replaced it and now my car barely turns over after solid cranking and pours white smoke out of the exhaust. Pulled the dipstick and it stinks of gas. I am so lost, can anyone help?

I'm running an Edelbrock performer intake and Edelbrock 600 carb with a Mallory return style regulator

 

Sounds like anti freeze. Maybe a cracked head, or bad intake gasket.
