Questions regarding main bearings

Post by dankberries »

I'm currently knees deep in rebuilding the engine from my 93 SS.
Im going to replace the main and rod bearings, my question is, is there anything wrong with mixing ACL H(STD) & ACL HX(STD) bearing to make a complete set?
I don't have a complete set of either one , but put together I have a set. Their both standard, I believe one is coated and the other is not.
So if I put the two together, is that OK?!

To clarify , #1,3,5 are HX and #2 & 4 are H
I'm not mixing a half bearing with another half bearing..if that makes sense.

You could probably do it, but I personally probably wouldn't.

Your oil clearances are good, I don't see why not. I probably would,engines are not that picky, and if it saves money do it.

According to the FSM:
.0004 - .0012 in.
#1 & #5 limit .0016
# 2,3,4 limit .0014

My #2,3,4 are between .0015-.002 which I guess is little loose than stock.
I wish I had a the right kind of mic for the job and I could come up with a more accurate measurement.
