Arg, it shouldn't be this difficult..

I've been searching the weeb and this site looking for the part number for stock replacment hypereutectic pistons for the 3400, basically any year application will work. STD bore and what ever overs bores are listed.

If anyone has an updated Federal Mogul catalog and could post that number for me, that would be great, mine is a 1996 catalog.

TIA

there was no 3400 in 96 IIRC... that may be your issue.

I'll look... I cant remember the number but I currently have a set of these in my 3400 but they are .030 over.

This is what I found from rock auto... H847CP 75MM is what the top of my piston says in one of my build pics. BTW this is a 2001 Grand AM application.

Thanks, that is what I am looking for.

IIRC '96 was the first year for the 3400, but I mentioned my pistons book date as a refernce to how out of date it really is.

Your catalog is over 10yrs old, doesn't things like that just age you when you think about it? lol.
