I see a lot of ads for 302 5.0 shorty headers. Having an '85 5.0 in my '75, does anyone know if these type of headers would fit or would the BFH have to be used
Those are shorty's for your motor in a 79-93 Mustang only. They won't fit in a Maverick/Comet engine compartment. You'll need a BF welding machine and a BF cutting torch in addition to the BFH to fit em.
Check out this long thread, it tells you about the Doug Thorley shorties. http://mmb.maverick.to/showthread.php?t=24841&highlight=Doug+thorley
