I was looking at these pistons

Wiseco Forged -3.2cc Dished Pistons for 3.905" Bore, 3.622" Stroke, Part Number K398X3905, includes file fit GFX rings and .927" diameter pins. 1.304" compression height for 6.125" long rods.

And these rods

Callies Compstar H-Beam Rods; 6.125" LT, 2.100" Rod Journal, .927" Pin CSC6125DS2A2AH

Now we're talking. I've yet to see any bad things about Wiseco. I have those very rods that you are talking about.....they will carry you into 4 digit territory.

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.

I personally don't have any experience with high powered boosted ls1s (Ls2 here). But I've witnessed personally a full weight 4th Gen go 9.30 at nearly 150 with the ls1. Motor makes around 800rwhp. And yeah, I see it a lot "it's all in the tune"...which isn't 100% true. While it is true that the tune plays a huge role in reliability, the fact is....Stock parts USUALLY don't live long when their power rating is grossly exceeded. If your motor isn't seriously hurt, it would be cheaper to just put pistons in it....and roll out. Buy really, I would do rings and bearings too.

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.

I believe it's and ls1. It came out of a 2001 camaro with the ls6 manifold on it. I did change the valley cover to the ls6 style.

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

Curious, I see a lot of people suggest #7 cyl as the weak one, is it pretty much due to a certain intake manifold design, like the LS1/6.

stevieturbo

And that was disproven many many years ago. Nothing to do with the intake.

I might have tightened it to tight. But I did notice the rubber its made of doesn't seem as flexible as the one I have now. But no big deal went to the local parts store for a new one.
