I just made this swap and tried the aeromotive EFI to carb regulator and it did not work. This is a complete list of everything I used total cost was around $1,500.00 .
Vic Jr Intake, Fel Pro 1250 intake gasket.
Holley 750 DP
Holley 150 Fuel pump with -8 lines and filter
Granatelli fuel pick up
MSD 8598 Distributor
Throttle cable & bracket assembly
Various AN fittings
I already had a MSD 6AL box so the swap was very simple. I have 347 with .600 lift cam and it would not idle with the EFI setup, first crank with the carb and it fired up right up and idled perfect. I locked my timing in a 34. I picked up .20 and 3 mph in the 1/4 mile.
