I found rod journal dia online but cant find what the stock main dia is? Please. Thanks, Dave

Trying to confirm this crank I just pulled is standard.

I found it. 2.950 mains, rod journals- 2.40

From my haynes manual: Main journal dia- 1982-1993: #'s 1-4 2.9495-2.9504" #5 2.9492-2.9502" ; 1994 and later: #'s 1-4 2.9517-2.9520" #5 2.9515-2.9518"

Um, Early year cuz its actually a 6.2

Skirt clearance 1982-92 Bohn pistons: cyl 1-6: .0035-.0045"; 7&8: .0040-.0050"

1982-86 Zollner pistons: 1-6: .0044-.0054"; 7&8: .0049-.0059"

1987-92 Zollner pistons: same as the Bohn pistons.

Hope this helps as you are probably using something like a Mahle piston
