I am using the FMS 302 to 351 SS Mustang headers and was wondering if the sidepipes will bolt up, or do I need the drop mounts for a proper fit. I also have cats.Thanks in advance for any advice.
Along these lines, what clearance issues have folks had with the older FFR frames (mine is circa mid '97) when putting in the 351 block? I've heard that it is a VERY tight fit. Is this not true? Also, what are the MAC "swap headers"?
Just curious, you guys with the mac swap headers.. how is the sidepipe alignment to the body? I kept my 302 headers when i put in the 351 and modified them for footbox clearance... it got me through the summer.. but my siepipes wont line up at all... just wanted to know if the swpa headers work fine thanks
Side pipes lined up very close with the mac's. Passenger side lined up closer to the front of the body cutout, drivers lined up just touching the back edge of the cutout. Also passenger side just a touch higher than drivers side.
Hopes this helps, Scott
