c4 carb conversion
I have a couple of things please newbie to vette
#1 Can someone provide me with the routing of the pcv lines or where all the vacuum lines go on carb conversion i have a line from the pcv to the purge canister under ds headlight not one to the carb. Could i use dual flow pcv to the purge selenoid to carb or will that make it worse im just lost for words. bought from gentleman and it was ran with out a line to the carb pcv port. could this cause power loss.
#2 I have a comp cam 12-382-2 and running a 600cfm edlebrock carb. My two screws for air and gas are both turned out 1.5 turns, smells super rich. i been reading that the pcv not venting could cause a issue am i wrong? also my oil fill cap is venting out engine exhaust fumes, i though it was supposed to come in the oil fill cap and out the pcv side?
#3 what is the best spark plug for the c4.
I just dont think i have the power i should have any ideas would be greatly appreciated.
so sorry if i confused you thank you in advance

Vette specific routing dont know
In general most sbc have a breather on pass side pcv on ds that line will (pcv) go to a fitting at either the base of your carb or intake
Some eliminate them and run 2 breathers prefer to have the pcv on a street car.
have you tried a vaccum gauge on it?
Edelbrock carbs are calibrated for stock type motors you may be running real lean they can stink too. If its built up Id go with lean.
Get your hose/pcv thing sorted out first, time it then go back
