+++5.3L Questions+++

Depends BRO. What all you wanna do. Call a local machine shop with your ideas and see what they recommend and what their prices are. I would bore it out to 3.905 and put some LS1 pistons and turn that 5.3 into a 5.7 get the crank, rods, n pistons balanced, new bearing, ARP rod bolts, New timing chain, Big cam, oil pump, push rods, valve springs, bigger injectors if u dont have them already...... That should kill ur budget

Budget what's that?
If your gonna take the other motor and just throw it in it shouldn't cust much to much to do some bolt ons and a cam. It all depends on what you want out of it.

What are you wanting to do with it in the long run?
