OK, I snapped a few classic engines this weekend.... I will post the others if we get a good response here.

Name It!!!! This one is easy, but tell the story about it. For bonus points: What is unique about the head gasket?

DC911S

Its a Boss 429 Mustang. Pretty rare and expensive if it a real one. Looks to be since you have to change the firewall to make it fit, thats what Car Craft had to do to get it in there…...

That would be a street strip or race car. Look no wipers, rear hood pins, so lift off hood, line hold downs not factory. Very cool engine

Prius?

No head gasket , steel O - rings.
Shock towers were modified and widened to fit the very wide motor. Mustangs did not have very wide engine bays to begin with. Firewall not altered, but additional bracing was added between the shock towers to the firewall which were located under the fenders. Also, the engine bay brace was a thicker one piece stamped steel unit compared to the base Mustangs, this car is missing this, among other factory bits and pieces.

What tipped you off?

What the heck are ... Those ... Things?

Are these the Carbohydrators I've been hearing so much about?

Dad had a 69 Boss 429! Show car and was amazing! I remember the total restoration on that car, especially having to work around those heads once engine was back in car!

Wow... excellent! The O-rings were called Cooper Rings... some websites said they were copper but they were steel... I held one. They dropped into a groove on the block and then later the groove was in the head. Then neoprene(?) rings were used for water channels and something else for oil channels. No regular gasket. The heads had four bolts around the cylinders and rings would be crushed when torqued down. To remove the heads, you had to remove the engine for some reason.

This technology was supposedly borrowed from diesel technology. The reason for the Cooper Rings was that gaskets would blow due to the closeness between the cylinders. The engine was designed specifically to run at Nascar which meant high RPMs solid for hours with a compression ratio of 13.5 : 1

Excellent observations. This particular Mustang was a drag racer. I stood two feet next to it when the owner fired it up.... it shook my chest.

Amazing you picked up on the lift off hood.

The car was called the Boss 429 but this was not its original name. What was it?

I saw a scan of hand drawn engineering drawing drawn by hand on 8x11 ringed notebook paper with this title on the top........
