no such thing as the 501

the '73 had the 500

he must have miswrote/typed it, it is in fact a 500

rare? ummm.... well, they were the mainstream enigne for Cadillac 1970-1976.... there are plenty of them around... just gotta know where to find 'em

Many people look at the sticker under the hood and think the "501" is the engine size but it's not. If you look on that same sticker, you should see where it says "472cid"......or something to that extent. There was no Cadillac 501.

I wonder how many 472's & 500's still exist and how many are still in use?

I wonder how many 472's & 500's still exist and how many are still in use?A similar question was asked on another board.....they were wondering how many 472/500 Cads were being hot rodded. I once heard that Edelbrock sells, on average, 450 Performer intake manifolds a year. That intake came out in the mid to late 90's. By those numbers, I would say that there are more than most would think. You'd think you'd see more of them though (with that many intakes being sold).
500's are getting harder and harder to find and 472's will be the same soon. If scrap prices stay up, more are going to get scraped.:helpless: If you want one, you better get it soon or you'll be paying alot more for it. I've got the 500 that's going in my truck and one for another project. I'd also like to have a 472.

Anyone know what is different about a car marked with the 501 on the sticker, or what is stands for?

I've heard that the "501" is an emissions code.......not sure if that's true though.
I wish I'd taken a picture of the one that was on the car I had.:banghead:
Can someone get a picture of that sticker and post it here?

I can still see that sticker in my head. My '74 Deville (long gone) also had one. I sure hope someone post soon to tell us what the 501 stood for because I am driving myself nuts trying to remember.

I thought the "500" was actually 502ci?

The 502 big block is made by GM Performance Parts. It has nothing to do with the Caddy 500.

Judging from posts on various forums, supplies of the 472/500s are drying up faster in the east and south-eastern US than in the western US, I presume because of climate/humidity differences. I still see lots of early '70 era Caddys in the west. Still, we are now pushing 30 years since they were last manufactured, and so they are bound to become more scarce. After rebuilding my '75 500cid, I bought another good running example for back-up parts. Also, I've found it is cheaper to buy an entire complete car than to buy parts (or even complete engines) at junk yards.
