Matching Numbers

Matching Numbers engine block.

I think I posted about this in my Facebook fan page about few weeks ago, but now i got better image quality and with that statement I truely have a matching numbers El Camino. Althought it's just a 350 cid, 250 hp with 2 bbl and turbo 350, but it's still a numbers matching engine block. Original block!

T1022CNN stands for T = Tonowanda engine plant, 10 = October, 22 = 22nd day of the month and CNN = 1970, 350 cid, 250 hp, 2 bbl with TH350

I can't remember what website we did use it to decode it, but here are few links to decode your own small block Chevy:

Now putting that in perspective it gives me a two choices: Do I want to keep this engine, rebuild and make it more powerfull or put it aside and replace it with LSx-motor as I have planned a long time ago?

Now one thing before you cast your vote, I don't have the original heads anymore, those were broken back in 2009, crack between combustion chambers. Then again engine was 250 HP version so those heads were going to be replaced in some point.

What do you think? Keep it or replace it?
