I was looking on AUTOKRAFTERS.com last night and found headers for 70-77 mav's with 351w swaps!!! They are PRT# ES9 and run about $350.00. If you go to their site you have to browse under "ENGINE" and then under "EXHAUST". They also carry a few more headers for 302's and I-6's. L8Rs
yes, I saw them last year when searcing for them. They are 1 1/2" primary tubes, which would be ok for mild 351's, but could become a choke point for anything else. As most of you on the board know, I ended up building my own custom headers--1 3/4x38-40 3" collector.
headers I just bought a set of Mac 1-3/4 headers for a 351 in a 65-66 mustang,they are long tubes.Have not tried them yet hope they work. That ES part no. that was listed earlier is a Tubular Automotive part no.Just FYI. Herb.
