Hey guys, when I was shopping for flywheels, the guy asked me if my engine was internally or externally balanced. A couple of people told me it was internally balanced, but I thought I'd see what you guys think for verification. It's a 6.0L out of a 2000 Silverado 2500. Let me know what ya think. Thanks again.

 

internal

 

Is this the motor that you are tryin to swap into a V6 5speed? I believe that the '99 - 2000 6.0 had a longer crank. If you are trying to mate this 6.0 up to the 5 speed, I believe it's not going to fit.

Somebody correct me if I'm wrong.

 

yes it has the longer crank. its about 7/16 longer and currenty have one in the garage. dont think its goign to work either but could be wrong

 

So if you stroke an '00 6.0 with a new crank, what needs to be changed to mate the Eagle crank to the '00 4L80E?

 

use a spacer off a 01+

 

OK, thanks.

 

I bolted my transmission up to it, and everything seemed to go together alright. I have the 5 speed and don't know if that makes a difference. I didn't have the clutch or flywheel on the engine, I was just maching it up, just to make sure the bolt pattern matched up. If that bolts up fine, doesn't that mean it'll work? I did a little measuring, and it appears to be the same.

 

The block and the bellhousing will mate up fine - that's not the problem. The problem is the flywheel and clutch. With the long crank, the flywheel will be approx. 7/16" closer to the tranny. Since the location of the throwout bearing is fixed, it will have the same effect as pressing the TO brg. 7/16" closer to the clutch, which will keep the clutch from engaging. Also, the input shaft on the tranny will be 7/16" further into the crank which could cause clearance problems and pilot brg. issues.

You have to get a shorter crank.

 

so the spacer from the 01'+ would just make it worse?
