GMC SLE 5.7 Automatic, Long Bed, 180k. Mainly for towing and would consider SAS.


It had coolant leak so decide to freshen up the whole motor.

I plan on re-ring the bottom end, but want to make sure I'm getting the right parts matching the current parts.

Piston GM 61A 10172839

Rod GM-45 18021941

Crank GM-45 18025277
GM-45 18019643

Oil Pump end cap bearing A-400 .001

I would need to get 4 of the crank each.

Would SEALED POWER 2056504M with standard size be good?

Holy over 3 years old update, time to get this bitch together and running, missing bunch of parts from in. Here we go, again lol. I got stock headers ceramic coated.

Bummer. Gonna get rid of this truck. Might as well buy another one that runs instead of dumping 4500 on crate motor

What happened?
First crank had insanely loud mistire/backfire (louder than shotgun) then adjust distributor. Still wouldn't fire up after that. Compression test shows above. I don't have space for tearing apart and store all components. As I'm about to head off for the season.
