It is a 454 2 bolt block with a 14015445 block number with t0316FBW cast on the pad above the timing chain. I could not find the "FBW" suffix code anywhere.. ?? any help? It came with truck peanut heads but im not sure if those were the origianal heads on the motor.

Can only find this so far from www.mortec.com (http://www.mortec.com)

14015445...454.......78-90...2 or 4 bolt

Would bet John Z will have the FBW suffix laying around somewhere :)
