Good morning...

I have a Cadillac engine and don't know which one I have. The casting number at the top of the left side of the engine says T495200.

Can any assist with what engine I have?

Thank you!

The "5200" block was used for both the 472 and 500.
Check out the link below. That should tell you what you need to know.

The 472 has a 4-1/16 stroke and the 500 has a stroke closer to 4-5/16. Just pull a plug and roll it over with a piece of straight coat hanger in the hole and measure the stroke. Get some other info though like these guys said. I started out with what I thought was a 69 472, because that was the car I took it out of, only to discover I had a 75 500!!!

Too bad it wasn't the 472. The 69' 472 had more power than the 75' 500. They dropped the compression way down with the 120cc heads on that 500.

It was surprising how powerful the 500 turned out though, I was thinking the same thing initially, but for an old workhorse truck the 500 was just right. Now I'm pondering the next project. I've got a 70 472 and a 73 500 sitting on the floor. I'm gonna stick one of them in my 80 FWB. The Eldo that the 500 came out of was a nutsy car, but that 472 is even more so, as you said. A 70 CDV I've got in the back yard has the same 472 and it will fry the tires right off the car. It's mostly the premium gas that it takes to run it that concerns me. In the end I'm probably just gonna bite the bullet and use the 472, because this is gonna be a low dollar deal. If the cylinders look good, the lower end isn't getting touched. The 472 should be the most power for the money.
