460 tolerances question
Rebuilding a 460 out of a 1975-ish Lincoln (in my '77 F-250 now), does anybody know tolerance specs for:
Cylinder bore, taper
Rod journals
Main journals
e.g. 2.500 or 3.000" +/- so many thou?
My max taper is 4 thou, ave. diameter is about 5 thou above stock 4.36" bore.
My main problem is a (up to) 5 thou OVERsize on some of the rod journals, i.e. 2.005" on some measurements but most are about stock.
I want to know if it needs regrinding or stock rings will be ok when torqued in to spec.
Thanks!
