Hello, I'm currently rebuilding a 1979 Z28 Camaro, the carb that it came with works well and I plan on re using it, however, the engine in the car was swapped out with a 305 (wasn't a nice surprise) so now that we have a real 350 block, we want to know if this carb will still work well and were not sure if it's factory specs or not.

It's a Roch Quadrajet

Much Obliged, I did lots of searching but it's not common knowledge enough to even show up on google.

 

650 CFM and will work fine.
