I bought a $114.00 for a set of Speedway weld up headers. Turned the kit upside down and bought 2 extra bends for my fenderwell headers. took 2 days to build them.
I have a 426 Dodge in my forty. None of the normal A or B body fenderwell headers fit it. Came across a set of up-sweep dragster headers at a swap meet for $80. Took them home and put them on up-side down. Had to heat and move some tubes. But they fit pretty darn good. Just another idea. Gene.
