Hey guys,
I'm new to this forum and have a question to run by you guys. I have a 37 Ford tudor with a '69 302, C4 auto, 9" rear. I'm currently rebuilding the engine with a few extras to up the performance. One addition is the GT40P heads from the 98-01 Explorer. With the different spark plug angle this creates issues with the headers. I need to use streetrod blockhugger headers to clear frame & steering but they will require modification on some of the tubes to clear the spark plugs. Many posts on Mustang sites I've read suggest dimpling the tube and various other methods for clearance. Wouldn't that restrict exhaust flow by dimpling a tube half shut for clearance? I don't know if the "P" headers by Mac will clear my steering & frame. Anybody have any experience with this on a fat fendered Ford? Thanks for your thoughts.
