Cool Bearings

Took the #1 connecting rod bearing out today, trying to find correct size to order.
On bearings it reads,

GM - (can't make it out, looks like 4 5)
18019665
5 H 4 2

Where do I go from here, I need this truck up and running before February what size bearings should I order to be safe, since these are from GM which tells me this engine hasn't been rebuilt before.
As always thanks in advance.

Re: Bearings

i might be wrong here but i was always under the impression spin a bearing = rework not just slap in a new one .

at least check and possible re-size the rod big end and maybe even new bolts and nuts .

Re: Bearings

If it was mine and the crank wasn't nicked or scratched, I would buy a set of standard bearings and a set of .001 undersize bearings and some plastigauge and use whatever bearing fit the best.

Re: Bearings

Great bearing prices @ Competition Products.
If the old bearing had spun it's guaranteed that the big-end of the rod is out of round.
