Also for those looking for a 4l60e a 2005 one from a 4.3 silverado has the correct ls1 style torque convertor. Fits perfectly. I updated with corvette servo and shift kit.
I was able to get a 4.3 one for 500 with 10,000 original miles. The 5.3 ones were a lot higher.
did the converter pilot fit inside the crankshaft center? Usually on those you have to put a pilot extension to the converter is supported.

Yep there is close to a 1/2'' difference between the SBC (4.3,5.0,5.7) 4l60e used and the LS (4.8,5.3,6.0) 4l60e used...
The convertor extension fit completely into the hole on the 5.3. I test bolted the convertor to the flywheel and the extension went completely in and fit like it was meant for it. The convertor was built with the dished flywheel design. Dont know if it was just this one or they changed them in 2005 but it looks exactly like a lsx style convertor. I did not see any space where an adapter extension would fit.
Good deal, sounds like you're ready to roll.
