anyone here ever use the shorty 351W swap headers for a 65/66 mustang on a 289/302 in a 65/66 mustang? My dad tried it and it wouldnt fit on the passenger side but he had the old style pre-66 motor mounts. I have the post-66 motor mounts in mine which are supposed to drop the motor 1" and provide extra header clearance. do you think these headers will fit on my 302? i have full length 289 headers now but the ground clearance sucks and i want to switch to shorties but hedmans set is 1.5" primaries. the swap headers are 1 5/8". want to see if anyone has done it before i go through the trouble.
