Help me out.....I am converting my 1991 LX 5spd car to a C4...50oz. 10 1/2 bolt pattern converter...my question is----which converter do I need..the one that specifies a 1.375 crank pilot or the one that doesn't????
crank pilot size varies with which engine you have, 289,302,351w,c, all have a 1.375 pilot size(don't forget to remove your pilot bushing in your crank)
the other crank size ford uses is 1.848 and is found in 360/390 fe blocks, some early
429, 460's i think 400 and 351m blocks.
