I'm on the bubble right now, the motor I'm getting done has a comp thumper cam, so it's not gonna have a smooth idle The Offy dual quad tunnel ram means 2 throttle body assemblies and the related $$. I've thought about junkyarding an EFI system together, but I just don't have the time for that and want to get the car running. I've got a pair of AVS carbs, now, so I may just rebuild them and get the calibraion kits. I have a wideband gauge for the car. I was hopeing for more info on the options down the line.
