Title: Tonowanda enging codes
Post by: oneZ11 on September 25, 2012, 12:32:53 AM
I was under the impression that all "T" code motor stamps were high performance motors. Is that the case, or did GM make sedan and 'base' level motors in Tonowanda? Could there be such a thing as a "T" coded motor that was not a 350/300hp for example?

Tonawanda built just about all production BBs and many SBs. Did not build 302s.

So not exclusive to "performance" motors. Okay, thanks for the feedback...

Tonawanda didn't build ANY "performance" (solid-lifter) small-blocks, but they built the full range of hydraulic-lifter standard small-block engines for cars and trucks (except Corvette - all Corvette small-blocks were built at Flint V-8). All big-block engines were built at Tonawanda.

Thanks for the info. So let me ask you this. I've got a 69 pace car with the original motor that's a "T" code 350/300hp. Would all pace car 350/300 blocks be "T" coded, or could some of them be "V" coded?

I'm asking, because I have a buddy with a pace car, and he doesn't have the original motor. We're looking for one...

Very common for Z10/Z11s to have Tonawanda-built engines.

Could any be "V" codes?

Yes. L48 engines came from both engine plants.

SBC 3-digit engine suffix that starts with "T" are usually out of a TRUCK application and are desireable because of the 4-bolt mains. If the suffix starts with "C" it is more likely to be for a CAR. :)

I believe oneZ11 was referring to the plant code at the beginning of the motor assembly date stamp

Yes, that's correct.
