Thanks for the info Fast68, I did not know that, well I'll soon have both options soon, I currently have the vac set-up right now, but am restoring my car with what I was told by the previous owner, that the distributor originally was without the vac system. They tried to get rid of the E4ME, said they were too problematic. I'm going against everyone's advice and sticking with the E4ME computer route. What's your take? Kevin.

 

if it runs good then leave it, if it runs rich like alot of the electronic Q jets do, then find another or swap the hei and carb for a non EST one and yank the computer and harness out, its all separate from lights and main engine harness(starter alt a/c HEI etc)

good luck
