NOS means New Old Stock.

How much is he asking for it?

Default 428 engine
Was it possible to buy a complete over the counter engine with timing cover, wpump, pulleys, all manifolds, and intake? I was always under the impression that a short block or long block only? Nice engine for sure.

yes NOS that is my understanding, this is a new old stock engine and its not a service replacement block. Not sure on the price.

I would think no 2 letter stamp on NOS. That would have been on production line for install.

Does your friend have a brother named Mark? That's just an unusual last name and I knew a Mark in Wichita Falls. Anyway this guy has ALOT of stuff for sale, I see his adds all the time when checking craigslist. I just wonder if he ever sells anything as his prices are kinda high. Good luck with the sale though, that is a really neat find.

How much is he asking for it? Forum rules require a price - there is no price in the CL add.

Default Not buying the story
The numbers above the XF would have matched the last digits of the VIN. One ugly motor for never being in a car and having always been stored inside.

I've got a '67 428, was a SR motor and stamped right in the block down where the vin would be. So who stamped the service replacement blocks the dealer or the factory?

No, the numbers above the XF are called the Engine Unit Number (EUN) and were internal numbers Pontiac used which tied the motor assembly to the chassis they were destined to go to.

This engine was was originally installed in a car. It is not NOS nor is it an over the counter or Service Replacement engine.

It is however desirable. Please post a price.

Looks like a low mileage engine pulled many years ago. Neat to see part of the original XF paper decal still present. I bet the original nylon-tooth cam timing gear is still in it.

Not sure how you get a numbers matching car without the engine/tranny/vin all being the same.

Actually, the EUN and VIN stamps are completely different. Here's the EUN & VIN stamp on my '70 XF 455 for reference...

Oh &*(^! Have I forgotten about a 2nd stamp on the block and I'm thinking of the wrong one?
