EFI considerations for a 1970 383 with very mid cam

Another vote for sniper. Heed their warnings for keeping the sniper wires (to sensors and such) away from ignition wires as well! I run mine with MSD distributor locked out and 6AL box.

Also agree with the instant restart difficulty. I think it’s just a little too much fuel, gets the plugs wet. You can usually get around it by holding the pedal to the floor to prevent the fuel priming.

Read up on the AE vs throttle position change parameters, will give amazing throttle response!

The MSD Atomic I ran previously ran great too, switched to the dual quad sniper setup.

A buddy of mine is going to multi port with super charger and is selling his used sniper setup. You can PM me for his contact info if interested.
