Main Bearing Clearances, Line Hone Needed?
I have a 72 YH 455 block that I have had for 22 years under my bench and recently decided to build it up. Stroker kit with forged Eagle crank. This weekend I set up ARP studs, stock main caps, FM bearings and the clearances were:
#1 .0015 #2 .0015 #3 .0010 #4 .0018 #5 .0018 (Rear) I set up the crank and torqued the studs to 110 and 140 on the rear. Crank would turn with all installed but #3, just too tight. Time for a line hone? I had the shop do a deck and bore/hone but held off on the line hone until I could check personally |
