Re: Edelbrock Performer RPM & Q-jet install question
Cap doesn't matter as long as it doesn't have the coil in the cap.
The carb fuel line will be in a different location, usually farther back, you will need to bend a new hard line, or just install rubber hose from the pump to the carb, but a hard fuel line would be much better. You could probably find a new hard fuel line on yearone for a rochester carb like you are installing, look for the ones that came off of the 350's with the q-jets.
Make sure you mark where the pointer is pointing on the distributor rotor, and don't turn the motor over with the distributor out. By marking the pointer and leaving the motor as it was makes it much easier by just having to drop the distributor back in, re install wires and fire it up.
