Question for sbc gurus

I Have a SBC in my Coupe with a sequence of numbers stamped on the pad on the front passenger side of block, V0503T. Under that row of numbers is another set of numbers C3J114351.

I have had no luck decoding these numbers. Any help will be apperciated.

 

So far all i got is your block came from Flint MI on May 3rd.

 

Apperciate any help. I have searched and searched and nothing.

 

Well I guess you found out it's a 1973 350.

 

Last six digits in the second number is also the last six digits of the vin # of the car that the motor came in....................................... Jeff

 

And the "C" indicates truck. Chevy car would have started with "1".

The "J" is the assembly plant for the vehicle, but I don't know what city that is.

 

check the number on the bell housing flange

 

I should have mentioned that the "3" (second digit) does indicate 1973 model year, though Rattle Trap suggested you already know that.

It can only be a 307/115hp or a 350/155hp. Aren't there any more letters after the "T"? The engine code should be three letters.

Yes, also what plymouth 1952 said.

 

Thanks a lot guys, that helps.

Plymouth 52, there is a casting number on the Bell Housing, but the numbers are so messed up I can't tell what the last three are. I am pulling the front clip off and engine out soon to put a Jag Ifs under it, maybe I can determine what those casting numbers are then.

54nomore, there are no letters after the T. I have looked till I'm almost blind trying to find more letters. Hard on my old eyes.
