Main Bearings...Need Help ASAP!!!

[XLR8ING]

Hey guys,
Finally getting around to putting my new mains in and when I went to put the crank in, it wouldn't go down all the way.
Upon inspection, I noticed the 3rd bearing (wide thrust bearing thing with sides) is too wide for the crank.
I looked at the old bearing, and it's definately been rubbing, but I think that's the point, to not let the crank walk forward or back.
But is it suppose to be that tight? It left marks on the outer part of the bearing where I tried to put it in.
I measured the two bearings, and the new one is 0.4mm wider than the one I removed.
Both have exactly the same part number on them, so is this new one defective? I don't remember having this problem when I built the motor, but I could be forgetful.
Thanks guys!

Never mind, I figured it out, and it turns out that once again I am an idiot. I accidentally ordered the bearings with the oversized flange bearing.

Hey Franz!! What are the cam specs in your Z, and are you using the stock ECM?

RE: Main Bearings...Need Help ASAP!!!

I've got the Crane 260 cam, with .427 intake, and .454 exhaust. I don't have the rest of the specs handy, but if you look on Crane's site, they've got them all there.
And yeah, using the stock ecm for now. Ben did a reprogram for me a couple years back, but I'll need that updated when this thing is done again.

sorry for not responding to MSN, wife was using the laptop and it auto-signed in =D

I would have just told you to get them replaced, i have always been able to spin the crank over by hand with the caps all bolted down.

No problem, figured it might have been the wife.
I got Ben online and he happened to have a set of bearings, but they had a different part number than mine. So I looked them up again, and I just grabbed the wrong part number when I ordered them.
Raven, the intake was done, but I'm redoing the upper portion so I get the proper length runners for my set up. And instead of two TBs like the last one, I'm using one LT1 TB.
As far as other stuff, I don't want to give it all away, but mostly it's getting things I couldn't afford, or didn't know before.
