Trying to id what size engine is in a freinds Pontiac Grand Prix. It's a 62 or 63 (can't remember what he told me) It's a V/8 with an auto trans. It has the eight bolt wheels on it. It's been years since I've even looked at one of these. If I remember correctly it was a 389 V/8 but also remember a freind that had another model that had a 421 with three dueces on it. Can someone tell me where the id is on a Pontiac engine and where I can get the id number verified?
Much thanks, George
If you look through your friends windshield you should be able to get the complete VIN code. There's a ton of information there that's easily decoded by service manuals or online information. Let's say the eighth digit is an "H" the engine could be an "LG4" 5.0 L V8 with a 4BBL carb. Search the engine for your stampings and you're done. The example I used isn't more than likely the engine, I don't keep 40 year old information very handy on my desktop.

We were told the engine is not original. Thus the VIN won't tell us what the engine is.. I need to find out where on the engine is the stampings that ID what year, cid, and model this engine came from.. thanks..
