I recently bought a 402 BBC and I want to know what it is rated at. The number off of the front pad is T0512CLB, the block casting number is 3969854, and it was cast in April 1971.

I've read that the "T" indicates a truck engine. Does this mean it is a tall deck?

Thanks.

The "T" stands for Tonowanda..the plant it was manufactured in
0512= May 12th
The CLB has something to do with the type of car it was from, transmission option or something like that
As for horsepower it's hard to tell. Best guess is 240-330 depending on what type car it came in, heads, compression. Lots of variables
