The T1012CWD is the buid code and usage suffix. The "T" is for Towanda (sp) NY casting plant. The 1012 is the assembly date (Oct 12th). The CWD usage suffix was used on 5 engines in 73 and 74. All were 454's and all with automatics. These were the '73 Monte Carlo with 235 hp or 245 hp, 73 Chevy and Chevelle with 250 hp, and the 74 Chevelle with 235 hp.

The Z132410798 is the VIN deritive of the car it was originaly installed in.

The 353049 heads are 73-84 oval port heads with 122cc chambers and 255/119cc ports.

The casting number, 3999289, is for 72-79 454's. Check the casting date (other side from the casting #) and that should tell you the year.

Thankyou very much Tom.

I bought the engine from an old lady and she told me a long story about this engine , but the importance point was this is a corvette engine that she ordered when she bought her station wagon. Anyway , i paid $350 for it and was going to use it for my 69 if it 's a vette engine, but now it 's going go to the truck. Thanks again for fast response.

Don't be too quick to ditch it. There is little if any difference between the 454 for the Vette and the 454 for the Chevy. Those heads have the same numbers as the 73 LS4 corvette engine. Usualy the HP differences between the Chevelle/Camaro/Chevrolet engines and the Vette engine is that the Vette has a less restrictive exhaust. The 73 LS4 was 275 hp. The engine you have may the the 250 hp Chevelle version. I would think that they could basicly be the same engine. I would be very tempted to add a good cam and headers, then bolt it in the Vette. It may very well make a great engine for your Vette. :D

How hard and expensive to bring this engine to about 450 hp and torque? Most of the stuffs that i upgraded for the car were considered the BB so it is adequate enough for the BB, Would 2k is enough for engine modification alone ?

I have no idea on the cost, but to get to 450 you would need heads, valve train, cam, intake, headers, ignition. Everything except the block. May need pistons to get compression where needed. Then you would need to look at how strong the lower end is. Could be that you would need to add 4-bolt caps, stronger crank/rods/wrist pins.

I do not think it would be cheap, but depending upon what was needed, the cost could possabily be kept down.
