-----If its the same Traco (and it looks like thier logo), its one of the most famous race engine builders ever. They were located in Culver City very close to Dick Guldstrand Enterprises. If Im not mistaken Shelby was somewhere in the vicinity as well. With factory assistance they were building HD racing pieces at least as early as 65 and probably earlier.
-----I once took a pair of square-port heads off a 66 427/425 Vette that had been "massaged" and were stamped Jocko's Porting Service. You hard-core HP guys will remember the name. I wanted to put them to use but ended selling them as I had nothing on the horizon to use them on...........Bill S
