Finally getting back around to putting my engine back together and when I check the main bearing clearance they are between 5-6.5 thou. Does anyone make a being that's just a couple thou under so I don't have to go a full 10 under and have the crank turned?

Short answer, no. Long answer, too many reasons why for me to bother. If you really want the details? Call a machinist and ask him.

You can either do it right or regret it grasshopper.

LOL! Grasshopper? You sound like another keyboard commando that thinks he knows more than he does. 🙄

Well let's see. The main journal's were checked with a micrometer. The main bearings and caps were installed and torqued and clearances checked with a dual bore gauge.

The engine is about as far from stock as you can get. Partial fill, fire rings, main studs, head studs, custom machined pistons, Crowder rods, etc. Made 806 rwhp its last time on the dyno.

Getting rebuilt due too piss poor machine work on the pistons from Mahle Motorsports causing cracking. The block was line honed and the crank inspected but they didn't have the bearings to check clearance. On assembly I checked clearance and found its out. I was hoping to find some bearings to make it work rather than having the crank turned.

I don't post on the forums much anymore after being on them for 18 years and being burnt out on the keyboard engineers but I'm hardly a grasshopper.

Kinda off topic, but do you have any pictures of this engine? Building process? I love engine building and it would be cool to see the process for this engine. I don’t have enough knowledge to offer input to your question. What should crank/bearing clearance be for this engine?
