I have a guy wanting to sale me a 2000 6.0l, with a spacer on the crankshaft.
What I want to know is will it work with my 2001 t-56 camaro.
Can the spacer be removed?
Help me out!

 

I see no point in buying the iron block motor unless you planned on tearing it down and making it a 408. Other than that, you could use the money to buy a cam or other mod and be faster than the 6.0. Pretty pointless unless you NEED a iron block.

 

My 346 hydrolocked and broke off the starter mount.
If i take the motor out I at least would like to up grade, at least a little.
346 too a 364 would be just fine, and I want have to spend the extra dough for machine work and internals.

 

I found this, and I will post it for the next person who has this same question.



Crankshaft Replacement Caution For
1998-2005 GM 4.3, 4.8, 5.3, 5.7 & 6.0L Engines

The AERA Technical Committee offers the following information on crankshaft replacement caution for 1998-2003 GM 4.3, 4.8, 5.3, 5.7 and 6.0L engines. Design changes in the flywheel flange thickness have been made to some crankshafts used in the above-mentioned engines. This bulletin is being re-published with additional information.

The later crankshafts are shorter on the flywheel flange as seen in the listing below. These changes are due to the many different vehicle / transmission combinations being built by GM.

A flywheel spacer ring GM Part #12563532 and a longer bolt set GM Part #12563533 is required when using a thin flange crankshaft to replace a thick flange crankshaft. Also, if the crankshaft is being used in a vehicle, which is a standard shift application, you also need pilot bushing GM Part #12557583 or 12479894.

Note: GM part numbers correct as of 12-18-04.

Years Liters Casting # Trans Flange Thickness

1998 early 4.3L 236, 255 V-6 1.62 thick flange
1998+up 4.3L 236, 255 V-6 1.500 thick flange
1999-2000 4.8L 312 V-8 M/T 1.250 thick flange
1999-2000 6.0L 215 V-8 1.250 thick flange
1999-2005 4.8L 482 V-8 A/T .857 thick flange
2001-2005 4.8L 482 V-8 M/T .857 thick flange
1999-2005 5.3L 216 V-8 A/T .857 thick flange
1997-2005 5.7L 216 V-8 .857 thick flange
2001-2005 6.0L 216 V-8 .857 thick flange

All GEN III crankshafts used in Camaro, Corvette and Firebird have a .857 thick flange and also have a freeze plug installed at the bottom of the pilot shaft hole. The 4.8, 5.3 + 6.0L don?t have the freeze plug. The drilled hole thru the centerline of the 5.7L LS1 & LS6 crankshafts allows a path to balance crankcase pressure within the lower crankcase. Doing so has eliminated possible oil consumption when the engine is operated over 4800 RPM.

Caution: Early crankshafts use a flat reluctor wheel and late have a recess. Recess will work on all years. Do not use a flat reluctor on late applications as it will cause an engine misfire.

 

Finding a reasonably priced long block shouldn't be to hard. The problem with the 6.0 is the compression is low. If it isn't a LQ9 motor, it will be low compression. You'll have to mill the heads and go with thinner head gaskets to get the compression to a decent range. No tto mention you'll be adding the weight to the front of the car. It's a toss up on wether it's worth it or not.

 

yea makes sense!
