H i guys ok im tryin to figure out exactly what i have i have the last 8 of the vin of the vehicle it came out of but dont know what it is and the engine id does anyone no i to decode these or where to go to decode these the numbers are T0613cka and the last 8 of vin is 13L23429 figuring out what that last 8 belonged to would be cool thanks

 

T = the Tonawonda engine plant; most of its output went into trucks; most trucks got a 160-165 HP 2-bbl or 180 HP 4-bbl wonder; the 2- & 4-bbl motors were absolutely identical in every way (heads, pistons, cam, etc.) except for which carb and intake they jammed on top of it.

THe VIN in the BLOCK stamping is a pre-80 one. Therefore the BLOCK is at least 31 years old.

The odds of a BLOCK that's THAT old still having ANYTHING ELSE original still attached to it, are so slim as to be quantum-mechanical. That stamping tells you ABSOLUTELY NOTHING WHATSOEVER about whatever someone may have done to it while "rebuilding" it. It's entirely possible that NOT ONE SINGLE PIECE, not even so much as a bolt, is original to that BLOCK.

Whatever you think you're going to find out from that number, you're probably not.

 

FWIW
CKA shows up as a 350 over several years
'72 /165 Hp 2bbl, man ,A , F or X body
'73 /145 Hp 2bbl, man ,A , F or X body
'77 /170 Hp 4 bbl B Body

 

CKA is also a 1985 305. A casting number can determine if it's a 305 or a 350 block.
