Buying 6.0 with a spun main bearing**PICS INCLUDED**
I have the opportunity to buy a 6.0 with a spun main for $350. I plan on rebuilding this engine and stroking it to 408. With the spun main, Is there any block damage that can be associated with this? I just want to know If a engine with a spun main could be rebuilt..
The guy also say the heads have a few exhaust bolts thats need to be removed. Is this to much work? I was just trying to avoid paying $1100 for a new 6.0 block

i purchase an lq4 a while back for $150 with a bad cam bearing, i rebuilt it to a 370ci and its been holding up fine.its been running for 5 months so far...i would go for it if it was me.anyway once you stroke it you will need a new crank

Without measuring it I would not pay 350... maybe 100 and that's pushing it. A new one would be nice... and really with the extra machine work the screwed up one needs you need to sit down and think exactly how much you save.. Leave the new block standard bore and go 402.

As long as the bearing hasn't cut into the block side of the main, it can be line bored and honed. But it can't cut too much into the main cap either being a cross bolt cap. I have a 6.0 that the cam bearing walked out on, and lost oil pressure and lost a couple rod bearings and and just moved the main bearing a bit. Cam journal housing mic'd on the money so I studded the mains and sent it to be line honed. Cleaned up nicely. It really depends on how bad the bearing ate into surrounding metal.

Honing and line boring. Maybe I was misinformed but, don't LS' have three different size cam journals? After line boring and honing would the appropriate sized bearing then be installed? Sorry, new to this engine machining stuff.
