You have to be INSANE to have long-tube headers on a big-block A-body Mopar!
I went thru all that mess & decided if I’m going to keep the car & maintain it, I’m not going thru all that trouble just for a starter because no telling when/where one will go out. My 67 383 Formula S has a vintage set of NOS Hooker 1 7/8” Fenderwell headers with an old 70’s white textured aluma-coating. While most cringe, I have only found 1 negative(cut fender wells but I kept the sheet metal I removed), I have found plenty of positives:
1-Super open/easy starter access
2-Cooler engine bay temps with opened inner fenders
3-header removal without disassembling anything.
4-open/unobstructed spark plug access
5-transmission clear/open around shifter linkage
6-larger tubes/collector
7-looks cool, plenty of people see them say they never have seen this set-up
