Some things I have noticed.

When I used the high performance series bearings and the stock mains on my 6.1 crank, i had .0018" main clearance, a little tight for racing. Callies makes a bearing that adds .001 oil clearance, its coated, and 3/4 groove.

The next thing as of 3/12/13 the set of 4 roller lifters thru mopar that were 60$ cost and 80$ list are now about $140 cost $230 List. So if you know a parts person you were looking at 240 or so for a set is now 560!!!


53021720AC was the old part number and the new part number is. 53021720AE
