I dropped the block and heads off today at Longs Machine. Can I do a .040 over without any kind of problems?

.120 over makes it the same size as an ls1. Just look for ls1 pistons.

What is the danger of going to a LS1 piston? Would I have rod concerns with that size piston on a stock 5.3 rod at 11:1 CR?

A 5.3, ls1(5.7), and 6.0 are all the same stroke with different bore sizes. A 5.3 block can be bored to ls1 specs. There are a lot more piston options for a ls1. Put the ls1 pistons on the 5.3 rods, rebalance and assemble. Its that easy!

Thanks man.
I am going to buy HP Tuners to tune this setup, would anyone have a base tune to get me started they would share?
