What kind of power do you think the motor could handle with those rods and pistons? It's my understanding the ls1 isn't the best for boost. I know a lot of it has to do with the tune. My tuner is really good and reputable. Just trying to figure if it's cheaper to buy a short block done already. I have a 70mm turbo with a .96 ar. If I bought a short block I'd like to use as much as I can from my current motor. Kind of on a budget as this is unexpected.

It really is as simple as what is your budget ?
The LS1 block with forged rods/pistons will still take you quite far. If that is where your budget stretches to, and if your existing bores are fine to take pistons without any machining work, then go for it.
If your LS1 block needs machined...then clearly that incurs extra work and costs.
Is it an actual LS1 or LS6, baring in mind most later LS1 cars actually used LS6 block anyway ?
Although they do both have fairly thin liners compared to some.

Don't waste your time forging that ls1. For all you know the block may already be junk you can't hone them out far at all. Stick a stock 5.3 in it cheap and enjoy the thing. If you want to stay aluminum block get an l33. No way would I forge an ls1 block when a stock gen 4 5.3 will hold more power.

Budget short bock Take a look at least parts. I have a couple of good short block options and I'm ready to deal
4.8 with wiseco forged Pistons Stock crank and gen 4 floating rods for less than you can refresh the ls1 and. It's ready to drop in.
Also have a fresh stock 4.8. Also fresh and ready
