5.3 cutty

iTrader: (2)

Swapped my 5.3 pistons out for the flattop 4.8s now the wristpin is tight in the piston.I can move it by hand but it isn't free lime it was before the swap.Is it ok like this or will it be an issue when it's up and running?
thanks is in advance.

I wouldn't run it, could make a real mess. Pull um back apart and measure everything, something's not fit right. If you seize a wrist pin you will be very unhappy. Good Luck

press fit pin bores or floaters?


might need a hone. last set i took in was $80 out the door.

i considered doing it myself with a wheel cylinder hone, but those stones are for iron and not suitable for non-ferrous metals
