yeah me too, I just got my fentons on this weekend, have an appointment next saturday for exhaust. The fella is doing it for $300 since restoring old chevy trucks is also his hobby. I have a edelbrock dual manifold I am going to use on the new engine, but if I had known then what I know now I would have used the clifford setup with a 390cfm holley 4 barrel. But it is way too far into the game now. I had to make special adapter sleeves for the intake with an extra 1/2" length to not run into the headers.
