Well for some reason I some of this does not make alot of sense...?
I am running part number L2238NF so does that mean non-floating pin...? If so then why are the full floating pin type pistons with that number on them...? The old part numbers just had an F in them for forged if memory serves...? Also I dont see any of the hyper-type pistons with an F on the end...? Also what would "AF" mean...?
Now not really doubting you (coldknock) but what are these other codes for...?

P or F, pressed or floating. It denotes the type of wrist pin retention used.

|LilSmoke||F means forged,without means cast.|

Thanks for your replys.
So what kind of pistons is the ones without the "F" TRW-2304 0.30" ?.

Sealed Power / TRW L2304F030
350 Small Block Chevy 10.63:1 CR with 64cc chambers, 2.4cc .100 Dome
Press fit pin. 1/16 3/16 Ring Lands. 1.560 Compression Height.
I came up with the same thing greg did except for the rings, my info came out of Summit Racing.

|RCastle||I looked at several TRW pistons,while I did not find anything written in stone,all part #'s with the "F" in the part # were flat top pistons.If they were dished or domed they did not have the "F" in the part # but would have something else.|

That sounds more like a Sealed Power number to me.
I looked it up.
Its all part of the part number L-2304F
11-1 compression ratio (with a 64cc head I assume)
stock pin bore .927
1.560 pin height
5/64",3/16" ring set

TRW Pistons Partnr.
I've tryed to search the web to see what kind of pistons i have but i can't seem to find them in any lists.
The top of the piston is marked "TRW L2304 0,30" and when i looked at several sites i only get partnr like "TRW L2304F 0,30" ?.
Does anyone know what the F stands for ?, Iknow the "L" stands for Forged.
They do not look like "flat tops".
Does anyone know or could some please submit a link on the subject.
Please forgive my bad english.
