I'm shopping for a set of headers for my newly rebuilt 283.
I've looked at several types, including some really nice stainless steel ones.
Will there be a significance difference in peformance between those with a 2.25" collector outlet & those with a 3" outlet?
One reason I'm asking is that I'll be putting stacks aft of the cab rather than a standard under chassis dual exhaust. These will likely be 3" - 4" so I'll have to add to the exhaust diameter via an adapter somewhere downstream of the mufflers/resonators.
I don't have a feel for the pros & cons of exhaust bore size beyound the simple issue of back pressure.
Is my first ex-wife right? Does size matter? If so, how much? (I'm not taking the truck to the strip) Is one size significanly better than the other in this application? Will it matter if I go from the 2.25" to 3" (or maybe even 4") downstream for the exhaust stacks?
Also, it's a 58 Apache so I have plenty of room in the engine box for either full length headers or block huggers. Is there any advantage of one over the other?
Please let me know what ya'll think.
THX.
