Wiseco PTS523A6 Pro Tru Pistons LS Series
Hi all
I wanna buy these pistons because they can be applied on the factory rods and stroke, but I'm not sure if it would fit in L99 6.2 camaro stock block. And if so, would I need to do porting or would it fit solely? Pistons details: Style: Dome Bore Size: 4.060" Compression Height: 1.335 Stroke: 3.622" Rod Length: 6.098" Pin Diameter: .945" Dome Volume :+4cc Comes*w/ Rings: Yes Cubic Inch: 375 Compression Ratio Chart: 65cc Head, 11.4:1 Thanks |

The bore is too small, factory is 4.065".

Texas Speed carries that part number, I'd give them a call and see if they are intended for stock bore. They are forged, so maybe the additional clearance is intended. Or could call Wiseco.

I would give Wiseco a call and see what they have to say. Very nice pistons do you plan on putting some power down with these pistons?? What connecting rods are you considering??

Also not knowing the condition of your engine you may need a over hone of the bores to clean them up, most new blocks get a alignment hone of .005 just to accept new pistons by the shops doing them...… so the rings are made not to the stock ls3 dimensions but .005 over honed size to fit and rings are for the purpose just like the pistons...say you want to spray down the road you need different rings, etc.... Not into domed little to gain from increased N/A compression, and BTW ls3 blocks area throw away only being able to be over honed .020 and just cast in sleeves not being replaceable.... good luck. You should just use a real competent machinist....

Yeah, coz it bumps the compression up slightly from stock. The beauty of it, that it's very quiet and you can use it with the factory rods (6.098) to add some hidden power. |

Following incase anybody has gone this route. I like the idea of gained compression for less than the cost of altered valve angle heads and assume the valve notches would increase p/v clearance eventhough they are a dome piston. And I am pretty sure I've seen them available for 4.065 and even 4.07 bores on wisco website.
