I can not figure out what is wrong my my 67 camaro with a 327. Since i had a edelbrock performer and 650 holley installed, It will not run right at all. It runs rich all the time, I've tried getting it tuned, but they cant stop it from running rich, itfloods after 10 minutes or so, and unless i idle extremely high, i lose oil pressure. I just recently found out that the parts that were put on are used, and came out of a hot rodded s-10. I believe possibly the jets could have been changed. Any idea's on what could possibly be the cause of this, and any possible solutitons.

if its running too rich, then it was not tuned correctly, you should have smaller jets i can garuntee, stock jets are around 65's for a 650-750's , I have 72's and a size 36 squirter, but that depends alot on whats in the engine, if its just a stock build 327, a 650 with stock jets will do you fine. it shouldnt run rich with the correct size jets installed.

Hows the fuel pressure? It should be no higher than 6psi for Edlebrock. How about a vacuum leak? Floats?
