I used ACL on the mains and rods in my engine. I've used Clevite in the past and didn't really care for them.

Ask your friendly local machinist to mic the rod journals. Then determine what clearance your engine calls for (probably .002) and go from there.

It depends on what your housings measure, what your journals measure, and what clearance you're wanting to run. You probably could just use STD size bearings and be fine, but you couldn't know for sure until you measure it all out.

Hello 3rd coast ,,,,,,,,,,,,I don't know how many miles You're engine/conn rods have on them but I just wanted to let You know that even without aftermarket rod bolts the rod big ends still become out of round ,,,,,say 100,000miles probably like .002" difference . The bearings I like are the King bearings but I don't believe they make rod bearings that are .002" larger outer diameter .
