I give it a shot....

TU137BH

T = Tonawanda Engine Plant

U = Probably 0 (zero) first character in date

013 =Jan 3rd

7BH = Probably TBH

TBH = '70 Truck 402 cu in BB or '71 and later Truck 350 SB

You need to lightly sand and really check out the characters to be certain.

Oh, Red w White Top, Ivory interior assembled in Kansas City
