EFI or carb. ?

[shovelnose]

All of what stampede said.

Carb is cheaper by far to upgrade. Plus easy to diagnose. You will need a distributor cause the one you have will be computer controlled. You need mech./vac. advances.

You need to pull the in tank pump. Way to much pressure for a carb even with a regulator.

However since you allready have the goodies for efi. I would work with it. The computer is a good idea. Have the heads been port-matched or anything. Are they stock 302 or 351 heads. Do you have an adjustable regulator and whats your pressure at. I think stock TB are 58-60mm. A little small for all that motor/intake and exhaust.

What gears/cam? Your setup would probably like to rev some. Damb that thing should be a rocket.
