Piston and cam # help

Hi all
I just tore down my 396 and can't find what pistons or cam I have. The piston numbers are 2312P and the cam has CWC cast into it and 252 h or e stamped into the end.Any help is appreciated. Thanks Bruce

Re: Piston and cam # help

Not sure about the pistons, are they flat top or dished?? As for the cam, it almost sounds like you have a Comp 252 HE cam which is a very mild cam for your engine. A good street cam for a mild 396 would be the Comp 282S solid lifter cam. Lots of low and mid range punch.

Re: Piston and cam # help

I'm almost 100% sure comp isnt CWC.
A lot of stocker rebuilds back in the 90's used cams with CWC cast into them.
I pulled one out of a 327 and cant remember what CWC is or stands for.
The 252 is likely a part or shift number.
I think PDQ is the only one on here that I've seen who has or knows the part numbers or even what the heck these cams are.
Maybe old crane or federal cams?

The only Mustang I'd ever own is a Fender.

Re: Piston and cam # help

The piston number looks like an old TRW number.It isn't listed in my Speedpro book.Maybe BillK has an older book with it listed.You might ask over on the Chevelle site they have more bigblocks than we do.

2312P pistons (?):

I think CWC is the casting mark for Campbell, Wyant and Cannon who made cams for a bunch of folks:

I was also thinking that they may be TRW's but had no luck finding the number.Greg they are domed pistons.As for the cam I'll probably replace it but was just curious what it is.Thanks for the replies and I'll keep plugging away. Bruce

Hi Bruce, you have some Sealed Power brand pistons there for the 396"-325/350 HP units.

These are forged and use only a pressed pin mount. No provision for "floaters"?

(Add) You can see in the photo below, these are the equivalent piston to TRW's #L2240NF!

The cam (blank) is from Camshaft Machine Co. Hard to tell who actually did the grinding, but it's most likely from them also! Having said that, it could also be a Sealed Power piece, but I would suspect it would have add'l numbers on it somewhere!

Thanks, Gary in N.Y.

P.S. We still have a few sets of these pistons in inventory, saved for some of the resto's we build!
