Just like it says, I'm trying to get an idea of what manufacturers make a piston that will work with a ls3 block that will have a 4.1 or 4.125 crank and a little clean up work on the cylinders to get in the 420/430 range. Any and all help appreciated.

I would give Brian Nutter a call over at Wiesco. He can make you a set. Great guy to work with as well.

Call Erik at HKE. Hes done pistons for those for us, and has the dimensions and all sitting on Nutters desk already Im sure, and Im sure hell take care of you on the price

Thanks for the input guys. So what I'm getting though is that their's nothing quite in a 'catalog' per se yet?

Diamond, JE, Customs would be my choice.
Most picton manufactures will set you up with a set of nice pistons.
Give TSP a call to see what they can do for you. They are always helpful there!

We could get a set of Mahle for you. What rod are you looking to use?

We have that piston in stock, and I even have a few of those short-blocks in stock incase you want a 4.1 stroke short-b

Hey there, I normally wouldn't post on this topic as as we're not a sponsor, but check out our website and you'll see the new parts for '08. Some are in stock and some aren't yet, so you'll have to call in. We've got another part number called the k462f series that didn't make it into the catalog in time, but keep an eye out for it....it's a flat top version of the k450.

The reason I'm posting is this stroke is VERY tricky to build a piston for. If a piston company gets it wrong, and they probably will,..your motor is toast in a few thousand miles. Use the brand you're comfortable with as long as you think the designer did his homework.

good luck, Brian Nutter-Wiseco Piston

What heads and compression and usage are you trying to do? I have done a lot of these that have no problems but its fairly application specific.

racer7088

Depends on the app and head you are using and compression and usage you want but there are a few shelf pistons that might work for you or might not. There's just so many combinations that it's hard sometimes for the piston companies to make a shelf part for everything with the umpteen heads and strokes and bores and poweradder scenarios the LSx stuff presents!

Also like Brian said there's some pistons out there that don't really work in that app but they are still for sale. I have an engine here that was built way up North near Canada (and built very well as far as machine work) with some custom JE's in it that are beautiful parts but burn a quart of oil per 150 miles minimum. They have some key things wrong with them by design and will never work but they probably cost 1500.00!
