I'll most likely be going with a Butler set up EFI. He's using the FAST system and Edelbrock Torker Manifold. Spoke with Chase there today and he said since the system is so adjustble, you can run almost any combo on it and it'll work well. They take the motor specs and planned desires and create an initial MAP Burn (right terminology?) for it and it should run pretty well. Then after driving a bit, I can make the needed adjustments to dial it in. It will be 3 years before I do this upgrade, so who knows what will be available then, or what won't be. The 1.65 rockers sound interesting. We'll see if I can stay happy with what I have for the 6 months I have left driving the car.
