Engine Stamp Pad ID

[Mark Z.]

It's a 454 BB 2 bolt main 289 block with a May 1974 cast date with a stamp pad of T0415TRH. What did it come out of? Thanks.

It originally resided in a late 1974 Chevrolet or GMC truck with 230 hp 454.

Also, I think that you're reading the block casting date incorrectly assuming that the pad stamping is listed correctly. The engine was assembled on April 15, so a May casting date is not possible.

Re: Addendum

You're absolutely correct. I bought the engine yesterday because it had a set of Canfield heads on it with a Crower roller valve train. During teardown I thought it strange I removed truck pistons and rods from the bottom end. Thanks again for the info.
