Thanks everyone. I guess I'll just play around with it. Secondaries to the engine is the easiest for the linkage hook up. Haven't looked at secondaries to the rear position. It's a holly 390- square bore on one of patricks 4-barrel intakes. Seting it up forward might make a difference but with the center hung fuel bowles it may not matter anyway. Guess I'll know if I get it wrong by the way it resonds during accel and braking. Won't be on the road for a few more months so i can always change it back if need be. Thanks also for the info regarding the springs on bottom of the radiator.
