I am currently building my 73 Duster and accumulating the parts for a 10 sec build and have a question about headers. I think I want to go with 1 7/8 primaries but the choices are slim from what I can find. How bad would 1 5/8 or 1 3/4 primaries hurt the performance? What headers are you guys running?
Here's the build specs.
Built 727 with 4200-4400 stall PTC converter
Narrowed 9" with aluminum dropout, True Trac and 4.11 gears
28x10.5 slicks
Total weight should be around 3000#
Thanks in advance!
