Pro-tour79, How does the performance of these Tri-y's compare to 4-tube style design? I do not see any lower mounting flanges on these Tri-Y's how do you guys connect these to the exhaust pipes? What is Ron getting for these headers? These Tri-Y's are supposed to give good clearance for the starter, oil filter, and good ground clearance, but how about the brake distribution block that is mounted on the DS inner frame rail on A-body cars? Is the bolt-up easier for these headers compared to the 4-tube style design?
