I have my eye on a 02 Chevy Z71 with the 5.3 130k miles on it, i just might get that girl if i can talk him down a little does need work shocks, both front hubs/bearings and a new pinion bearing but it runs like a champ u think that 5.3 could handle 75 shot Nos?

If you have no dead holes and only some piston slap,dont waste your money on a engine.
Sounds like you have a pocket full of cash burning a hole in your pocket.
If the motor is broke,i would go buy used and spend $600 and call it a day.
Go buy something with a 5.3 or 6.0 in it.99+ GM

I would also not waste time with the L31 Vortec SBC engine. Been there before!
Good luck OP, keep us updated.
