Hi all,

I am trying to price my rebuild with diffrent options. Can I opt to reuse the stock 3.898 pistons if I hone the cylinder walls .005" ? If so can I use a set of 3.903" rings on the stock 3.898" pistons ? Help a noob out

This ain't no small block chevy, old one at least...

No and no. You need pistons and rings to match the bore. This ain't an old farm tractor engine.

Thanks guys,

I understand where your coming from. I was watching a pretty good ls1 rebuild series on Youtube by "MrWhiteLS". He reuses the stock pistons and rods after using a stone hone on the cylinder walls. He dosent specify what size rings he goes with. I guess he went with a VERY minimal hone with standard .00 rings.

He was prob just deglazing the walls with a fine stone, did he use a 3 stone or brush hone?

That' sounds right. I believe it was a #280 3-stone. I guess with a delicate touch there is not any measurable material loss to the overall bore diameter?

if you have to hone it out that far I would look into some after market pistons...

need new pistons .consider a 383 stroker rotating if your budget allows .

With the wide range of off-the-shelf high tech coated pistons on the market at reasonable cost, why would you want to re-use old pistons?

The only caveat to buying new is you should have your rotating assembly re-balanced, which is usually part of a decent re-build anyway.

That's the path I am going. I was curious about my options if I had the machine work done for the .005 over and then had to back out (if money becomes tight) of the stroker and reuse stock pistons to save a buck. I suppose if I can't pop for the crank I could just upgrade the pistons to match the new bore.

What are your goals with this engine power wise?

Is there something wrong with the OEM pistons/rings?

The stock Hypereutectic pistons are made to run with min. piston to wall clearance, like .0015 to .0025, anything more and it would rattle loudly at all temps. Go forged and upgrade your rings to file fit at the same time regardless of stroke. The Hyp. pistons are nothing more than cast piston with high silicon content to reduce expansion.
