I just went from TFS street heat, AFM powerpipe, 19 pound injectors, and a chip to a 750 Holley-Performer Rpm combo. Went from 12.0s@113 with Efi to a 11.55@114 with the carb. I was VERY inmpressed at the difference. Works very good.
Here's what I did:
Holley 750 Carb
Edelbrock Performer RPM
155 EFI style pump (cranked down with a regulator)
Braided fuel lines mated to stock lines under car
Lokar throttle cable and bracket
MSD distributor mated to a CRANE Hi-6 Ignition
Hardended distributor gear
Air cleaner
Fuel Fittings
Arp intake bolts
Intake gaskets
Thats l can think of right now. If I remember more I will let you know. It's a detailed job.
