98 ls1 spun rod bearing debating rebuild my block or grab a 6.0 lq9 short block and put new rings bearings and arp rod bolts

My budget is about 1000-1500 for the short block

And I don't think I can reuse my factory crank it got ate up pretty good

If that is your budget, then I wouldn't think about a new block. You can buy a GM crank around here for a good price and get a forged rotating assembly i.e. rods, rod bolts, pistons w/rings, for about 1400 bucks. You probably scarred the cylinder walls so I would have them machined out to a 347 c.i. and adjust as needed.

You can get a low mileage LQ4 for ~800 then use the extra funds for cam/springs/pushrods. There's a company called LKQ that has good deals on engines, and you can source the other parts I mentioned in the classifieds on here.

Yea debating on either the 6.0 swap or forged rods and pistons on ls1 with stock crank my plans in the future are maybe see 500rwhp on h/c and 100 shot or t76 on 8-10lbs but that

Also was wondering what you guys would do this car was just bought motor was STOCK
Everything that I was told had a rebuilt motor in about 10000 miles I tore the complete motor apart and The 5 rod bearing was spun all the way in the crank almost as one piece it got the crank pretty good but cylinder walls look perfect and I can see the cross hatch the full length off the sleeve

What machine work do you think is needed can I just put a dial bore gauge on it and buy new set of pistons and file fit rings

Im paranoid about that kind of stuff so regardless of how it looked, I would still have a shop look it over but thats just me. Anytime you spin a bearing, that rod/piston is going to have some sort of play in the cylinder wall.

U can see on the top of piston 5 where it slapped the head it's barely noticeable and hardly left a mark on the head but I'll prolly send it all the machine shop
