Motor Mounts for 454
I’m speaking from experience. 1976 C10 frame brackets are absolutely different than the ones from my donor truck 1979 C20 3+3 Camper Special. (I’ve later salvaged a 1974 C20 454, and they were the same as the 79) As Paul Harvey would say: “And now for the rest of the story.” I’m putting a...- DonL

Patriot H8054 Big Block headers
PS. I’ve also had to install a Vortec starter on my setup. No room for a full-sized 10MT starter. Just an FYI for anyone considering a set of these headers.

Patriot H8054 Big Block headers
Has anyone installed a set of Patriot #H8054 headers on a 2WD pickup? I bought a set, and have at least 2 issues with them. 1.) the collectors are angled towards the frame on both sides. Is this just sloppy design and/or welding? I am using 3” exhaust cutouts, and the angle puts them way too...- DonL
