OK, I know this question has been asked before, but my search in the archives yielded bupkis. Most probably operator error. I have installed a Holley 4175, 650 cfm, with vacuum secondaries on the 28 Essex, '79 Buick Turbo. So, what to do with the PEVR? I know there is a hobbs switch wiring diagram, but can't find it. Do I need it with this carb? Also, I remember reading there is a replacement for the ESC that someone on the west coast made. Does any one have a contact and has anyone used the system?
Thanks

Do not even mess with the PEVR if your using the the Holley, it won't be needed. The secondary circuit will provide enough fuel.
J&S is great but a lot of $$$
Stand alone spark control will work better than relying on the factory ESC or a combo using it.
