If it's a D2, it's a 72, and there is actually a build day/month/year, cast in it. Check the build date on your driver's door side, month/year. And did you know that the 429CJ 4 bolt blocks were put in any car with a 429/460 after the 429CJ/SCJ were discontinued? Deck height changed for emissions/comp. The kit is mainly different because of the EGR gaskets. Plus there is also been changes is valve cover gaskets, cork/rubber. Check the casting date on your differial housing, bet it's from the 60's.
: I was looking for a rebuild kit for my 73 302. Many places show two kits. They show a 72 and earlier kit and a 73-76 and then a 77 kit which happens to be the same for the 72 and earlier. It says the deck of the 72-earlier and the 77-up is shorter, while the 73-76 has a taller deck. Here is my problem: My block casting number is D2** which means it is a 72 casting, but my car is a 73. Is the D2 casting going to be the same from a 72 as a 73, or is it going to change because of the year of the vehicle even though it has the D2 casting? I always thought all 68-80 blocks were essentially the same, guess I was wrong. I just don't want to buy a kit that is wrong.
: Can anyone confirm which deck hight the D2 casting is and be absolutely sure the D2 casting didn't change for 73 model year vehicles built in 72.
: Thanks.
