Engine Code Identification Help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ravenmocker · 09-09-2007, 11:22 AM

The engine markings I can locate in my 1972 K10 Stepside are marked as such: K 02 05 TMM....I have another number located as: T4B513513.

If these were copied correctly from the motor, what type, size and year is this motor? I am unable to locate the exact answer. The T could be Towanda plant? the K maybe another location? The suffix of TMM shows maybe a 1974 or a 1980? I hope someone can point me to the correct size and year of this motor. I currently have a Holley carb with the number 85111-1 and 09111 on the engine and cannot identifiy the carb either. Any help is appreciate for a "newbie" chevy owner.
Thanks
