SBC engine identification help!

Just got and old 70 pick up truck with what looks like a mid 60's 327 or 350. It has the breather on the intake. I got the engine pad info 18c123675 TO02I9HC. I can't get to the block casting until I pull the motor it is to close to the fire wall. I found one website that said 69 350 out of a A,F,X body is this correct. This is a 69 350 I think coded for a M/t

That code was shared on nearly everything from 1967-1969.
Specifically your CON VIN & February 19th of 1968 engine code is saying it originally came in a 1968 Passenger series 327/275HP 4bbl w/PowerGlide trans. assembled at the Southgate Calif. plant.

Thanks alot for the reply. I thought the 1 was an I that makes more sense.

I checked the engine pad again it is 18c123675 T02I9HC. What does the I stand for in the suffix I thought that was the month?

The one probably was an I, and it was common for I's to be used in place of ones. On my 68 427 the code says TIIII1E, when it actually should say T1111IE

Sounds like you got yourself a large journal 327

[jasonL78]

what castings have the large journals. So I know when I pull the motor out.

[YENKO DEUCE REGISTRY]

I think the large journal cranks were by year, '68 was the first year for them I think. I have a '68 327 stashed, a just in case engine

It's possible it's a #660 block,but looking at your assembly date,I'll bet it's a #678 block.
