AMC Trans Am Engine

Forgot I had this in the corner of the shop crated up....never even looked at it until today.
Thought some of ya'll might like to see some pics.
Still wearing the Traco trademark gray engine paint.
Spose to have some help here today to get it out and clean it up.

Yea, I thought it was cast without them but after I got it out of the crate I can see where they ground it off.
Everything I have ever heard or read about the early 70s Trans Am cars was that they ran a destroked 360....all this stuff is 401 stuff and I believe it is Roger Penske stuff cause the block is stamped RP with what I think is some kind of serial number.

update, I don't think it's a Trans Am engine but a Penske NASCAR 357" motor, 11th one built.
