Installing my rebuilt powerdyne with 6psi pulley on my 87 Gt for the first time since the rebuild. I went front having it on a stock 5.0 to recently adding trick flow 170 heads, Holley systemax intake, N41 cam, 60lb injectors, Holley terminator x efi, I know the instructions say on a stock car to set timing to 6 degrees but that seems awfully low for my current set up. Just curious what everyone else is running at. Any help would be great as I plan on firing it up tonight.
