Here I go. As you might remember, I purchase a 72 LT-1 with air this past summer. It doesn't have the original motor in it though. The cam, heads, and intake are correct for my vette but the block is from a 73 Z28, which is basically the same thing as a LT-1 motor except for the cam. I guess somebody gernaded the original bottom end so my question is, should I try and locate the right dated block. My vette was built in late April of 72. So I would need to find a block that was cast maybe in late January or early Febuary? Does that sound about right? Or should I even bother because it won't be the original block anyways? My plans for this car are to drive it. It will not be a show car. Thanks everyone in advance. Sorry so long. Ray
If you want to drive it let it be. It will never be an original motor car unless you counterfeit the stamp pad. The vehicle is not rare enough to go thru those motions.
If you where interested in pursuing the NCRS Top Flight award then you could play with casting dates etc. This can be a very expensive pursuit if you have the means and the desire to do it.
When my father owned the car for 2 years he went and searched for an original 72 block wit hall the right numbers. He even had the pad stamped. I redid the car for him and put in a LT1 short block. The same shortblock is still in there. The original numbers correct one is residing in my basement gathering dust. I would not waste my time searching for one unless you are going to NCRS with the car. If you are going to drive it and have fun just use the block you have.

I disagree with this point. There were only 240 LT-1's built with A/C. Since the engine option is coded in the VIN, I'd say that this is a very desirable car from a rarity standpoint. Finding the correctly dated block for use down the road would be a wise choice in my opinion.
When the Chevrolet records become available, and all the bogus big block cars are exposed, this kind of car will jump even further in value. If you have a correctly dated block to go along with the car, you'd be in an even better position to gain value in the car.
If it were my car, I'd keep it as original as practical, find a properly dated block and store it for the future, and drive the car and enjoy it as is without making any mods that couldn't be easily removed down the road.
Just my opposing $0.02, as I am usually the one going against the "it's your car, MOD IT!!!" crowd.
I did not see that it was an AC car. It is rare indeed. Enjoy the car the way you like it and if you come upon one pick it up. The LT1 AC cars can bring pretty good $$$

I just want to second the opinoins above. If it is just going to be a driver, I would not bother with it and use that money to upgrade the existing parts on your vette. Mine was numbers matching when I got it. I have since went way away from that. Mine was not all that desireable when I got it so I just made it the way I wanted it to be.
Good luck with yours whichever way you decide to go.
Dave, Do you mean LS7 big block? I can't imagine working on a big block in one of these vettes. You barely have enough room with a small block!
That sounds like a winner with finding a block and just keeping it aside. Those 010 blocks are a dime a dozen around here. I'm pretty sure I should be able to find something. As long it's a 4 bolt main.
Just called GM today about that restoration package. They said it would take about 4-6 weeks. Can't wait! Thanks for your opinions. I hope that someday that they will find the documentation for our vette's. My tank sticker is pretty much useless.
I think he means the new LS7 motor used in the C6 Z06. It is going to be available as a crate motor. 427 CI LS1 style motor. I wonder what the $$$ figure for it is. 500+ HP sounds pretty good to me.
You have to decide what you want. IMO, if all you want is a nice driver, sale the LT-1 and buy a NOM base car and build it the way you want. If you want a 72 A/C LT-1, build the car that way. LT-1s with A/C are some of the rarest and most desirable C3s. The more correct that the car is the more valuable it is. Also, going original does not prevent the car from being a driver. Bottom line, do what you want.

It seems odd to me, their were only 240 '72 LT-1's w/air because they came out late in the year. But I see so many for sale and talked about... Not saying that you don't have one, but I would do my homework...
