Im not real up to date with ford 6's...however I built a 250 chevy for my old pontiac ventura. I used clifford 6=8. i had the alum. 4bbl intake,6 into 1 big header, 2.5" exhaust,high rise alum valve cover(for roller rockers) but never got those or their cam. I did a dyno pull...and hit about 140-160hp and 270-290tq at the rear tires. it was very good, but still not a v8 killer by no means. my buddy Hank(buckdupbronco) has a 6 also, which he bought their 6into2 header..not sure if he every installed it, cuz he had to weld in and separator in the head.I know i spent a bucket of freakin money with clifford...like 1200 or more WOW~!
