<_< I have an 79 Ford F-150 that had a 300 six cylinder in it. I am putting a 351W in it's place. The two biggest problems I am having are with the header/exhaust manifolds and the clutch equalizer mount that goes onto the bellhousing. I cannot find the mount anywhere in local junkyards. I am told that the mount is the same from 1973 to 1983 F-Series trucks, two or four wheel drive, as long as it is a 302 or 351W motor with a standard shift. The other problem is what headers I should use that will not give me major clearance problems. Any help would be appreciated.
