Can anyone identify numbers small block T4F708722 VI121TMM THANKS
I can tell by the suffiz TMM that it is not a Corvette block. I only have Corvette by the Numbers. Maybe someone who has Chevrolet by the numbers can tell you more.
It's a 327/250hp automatic, made on March 25, 1965, out of a '65 Impala/Caprice; the first character of the "2 2 5" should be a letter, most likely an A, B, or C (for Jan-Feb-Mar). :thumbs:
Thanks John for providing the info. Unfortunately, that block ended up replacing the original block in my '64 when a con rod let loose one day while idling at a stoplight and cracked it .. That one still bugs me! :lol:
