    Since you are pulling it out of a Deville, you would probably want the 472. By the time the Devilles got the 500, the smog laws choked them to almost nothing. The older the engine, generally the higher the compression/less emissions crap.

    Many people think that number refers to the engine size but it doesn't (I think it might be some kind of emissions code or something). If you look to the left of that number (on the same sticker) you should see that it says 472cid.

    As for what's best.....they're pretty much the same except one is 500c.i. and the other is 472c.i.. Some people actually like the 472 better because it has a shorter stroke and may rev a little quicker. In a small light truck, I don't think it'll really matter. You'll be smokin' the tires with either.

    little off topic but the folks on www.astrosafari.com say it is easier to put a v8 in a astor or safi than a s-10. Nothing says that a astro with a v8 lop

    Hi I wanted to add some information about the sticker and the engine size. The sticker is an engine model number. I agree with an earlier post that I have found that the cars with the 501 sticker have 472CID in small print on the same sticker. In addition, I believe that the sticker on a car with a 500 will read 776 with small print that says 500 CID. I have gotten into arguments with folks about whether or not the biggest cad engine was a 501 or a 500. I believe that the argument stems from these 501 stickers being miss-interpreted to mean 501 CID. Dave
