You may have broken a clutch finger, it's happened to me many many years ago in a 75 ford van. Luk clutches have always worked for me in light duty trucks. Thats anything that doesnt pull a bobcat or have a dump or cargo box on it. Centerforce or Mccloed shaeffer if your working it.

Welcome to FTE

Seems to me that the problemo may involve more than just the clutch disc/pressure plate...if it pertains to these parts at all.

The 400 uses a 12" clutch and the 351m uses a 11"

thanks for the breakdowns numbers dummy. I wasn't thinking linkage issues just because the pedal feels fairly normal. ill find out if I get it pulled out this week. Im gonna try and print those though they will more than likely come in handy. I plan on building this truck as my wallet allows. I want a good solid dependable workhorse when im done. Be able to drive cross country without worry and still get off the road and root in the mud when I feel the need. A 400 crank and pistons, 600cfm carb, aluminum intake and 2 bbl heads, Decent headers and exhaust should get me at least 325hp. Axle lockers seem to be a must have as I wasn't real impressed with it in the mud.(I thought I got stuck way too easy!) I work on mining machinery in an underground coal mine so im hoping with the help of this forum and my mechanical experience I can build a rock solid workhorse.
