If a clean low mile unit becomes available I think i will go that way. If I build a bullet proof 4L60 I could have over $800.00 in parts in it.

Thanks for the input.

budget in some extra cash for the conversion to a 4L80E unit....

drive shaft mods , fresh slip yoke, crossmember mods, wire harness conversion , ECM re-programing....

i may have forgotten something

Dont worry how old you are... it is the mileage on your body that adds up.
