question about crank and rods

tireburner163 · 10-20-2001, 09:45 AM

Ok I know this is a stupid question but I just don't know the answer. I'm re-building a 302 to go in my car. With the crank and rods can I just slap new bearings on them and go or do I need to have them reground.

thanks in advance

I've heard a lot of people do it that way, but if it were my 5.0 (which it will be in a little while here

), I'd at least inspect it, take a micrometer to it, and refinish the journals with emery cloth. I'm going to either have mine turned down 0.010" and rebalanced, or just buy a crank kit which consists of a crank and matching bearings. Most auto parts stores have these available, and some offer a selection of no more than 0.010" turned off. Also, most of the time, these crank kits only cost about $140. Can't beat that for peace of mind when you're revving past the redline.

Why are you rebuilding?If crank is not rough
you don't have to turn it.A crank that HAS NOT been turn is always better then one that has been turned.You can polish it with some fine emery cloth.
