Wow... thats a lot of sh*t for a spun bearing. Should I replace the rings too? They can't have more than 10 hrs on the engine. Also should I tell the machine shop to regrind the crank (if it can be) at some different clearance than stock? I read somewhere that jets need more clearance. I told them it was for a jet the 1st time but they may not have been aware that it needed different clearances than a car... On a good note, the rest of the motor looks good, not a scratch or gouge that i can see or feel with my nail. If I have to get a new crank can I get a stroker crank or will that change everything(meaning need new rods or pistons also)?
rings should be fine, as a general rule bearing clearance should be.001 for every inch of journal. so if you have a 3 inch journal you should have .003 clearance (disclaimer) these are just genaral guide lines the end user or builder will have to make his own descisions.
as for having the machine shop cut for clearance, you will need to tell them what you want after you get new bearings and install them and measure so yo can find out what size you have, and then you can tell them what you want the crank to be. if it were me i would have #1&5 rod's resized, it was #1 that went rite? do you know why this happend? if not you need to, so it doesnt happen again.
as for the stroker crank, you will need new rods and pistons as well. if you have a couple of grand to spend then go for it, best money i ever spent. But just dont think you can buy a stroker kit throw it in and call it good, all components will need to be measured and checked before assy. i had to send my brand new stroker crank in for clearance because i was not happy with what i got out of the box.
hope this helps, ralph
