Old TRW Catalogue, Any body have one?

Back in california, checked my 88 trw catalog, no 2297.
However, 2287 is a gigantic dome rat piston for a 396. So that begs the question: what is the diameter of the piston you have? 4.124 for a +.030 396, or 4.280 for a +.030 427/454? (Minus piston to wall, of course). And what is the compression distance? 1.760 for a 396/427, or 1.645 for a 454?
