Does anybody know what size valves are on a 5.0L from an 83 Caprice with a 4 BBL Quadrajet? I was just curious. I'm converting the engine to alcohol with a 750 CFM Quadrajet from a 78 C-10. Just a little note there.
Please note that I did not actually go out and find an 83 caprice 305
to measure the valves on, but these sizes are very common on RPO - LG4 engines from 1978 - 1988 305 passenger.
The only way to be sure is to pull the head off and measure them.
Good luck with your conversion and let me know if I can help you with anything else.

Hey man,
I had a sm blk. with 305 heads and those sizes are right, and they will most likely be a 64 or 58 cc chamber which will increase compression over an open chambered head so be careful with piston selection.
Horsepower is how fast you hit the wall
Torque is how hard.
I would like to put some 14014415 heads on my 350 I have 4 valve indents on my pistons and I have a Q-Jet and headers on the engine 60 thousand miles on the engine.Would like to get around 10 - 1 comp .. Thanks
Heads
