I need to know the particulars on a TRW L3065F piston. I know they are forged flat tops for the 2.8 V6 but I'm not sure if they are standard bore or oversized. Any help would be appreciated. These pistons will be for sale, BTW.

Thanks!

Bump...No one?

Chester,

Not sure what you want to know. Just mic the piston and compare them to the std. bore size in the shop manual. The number on the piston won't tell you if they're OS or not. OS pistons normally have that marked somewhere on the piston as well, but a micrometer is the quickest way to find out. Do you need to know the stock piston diameter, is that what you're searching for? I can walk over to the shop and look it up for you.

That would help.

Thanks

Chester,

Sorry for the delay. Shop manual lists it as 88.992 mm to 88.070 mm.

88.992 millimeter = 3.503622 inch
88.070 millimeter = 3.4673228 inch

Hope that helps.

I found the paperwork from the motor and the pistons are forged TRW at .030 over. The heads from this motor have a performance valve job and are plained .020 for more compression! It was an awesome motor until the main bearings went. Wasn't to the knocking stage, just no oil pressure when you stopped.

Thanks John, I'll verify the info I have with a gauge!

I think it's 89.070 not 88.070mm.
