I like the Clevite stuff.....

Keep in mind that even though it's for a street build, everything depends on the bottom end of the engine.....so don't scrounge on this part.

I would at least use the H series of the Clevite bearings. It's a little more expensive...but like I said it's worth it. The difference between the P series and the H series is huge....Especially if you're using a bore mic to mic the mains....you will see the difference.

As for what year bearings.....your block is a 74 model block. The mains should be 2.9999".

Do yourself a favor, spend about $120 on a good bore mic that reads to the half thou. Don't use that crappy dentalfloss stuff (plastigage) on an engine build. It will come in handy...especially if you're gonna blueprint the engine.
