Chevy engine blocks origin ?

Tim,

Looks like blocks with a "K" cast into them come from General Motors of Canada (McKinnon Industries Limited) St. Catharine's, Ontario.

Got hold of an engine core once-the cast date on the block at the rear was E127-May 12,1967. The stamping on the pad in front of the right head was T 0515 XX{don't remember the code- it was for a 327 250 horse PG trans type of thing.That engine was final assembled and ready for assembly line installation three days after the block was cast. Talk about a real seasoned casting!
All the 348,409,396-454's were Tonowanda engines. The small blocks were if the stamping on that same pad started with T. Also, the Tonowanda engines had a silver sticker on the passenger side valve cover that said,Tonowanda the Number 1 Team.

Flint, Michigan was the machining and assembly point of the small block chevy. Saginaw gray iron plant cast the blocks,Heads,Intake manifolds, cranks and connecting rods. Chevy in the hole plant in Flint on Chevrolet ave. made the cams, valves and valve train pieces. AC Delco plant in Flint on Dort hwy made the valve lifters, spark plugs, air cleaners,oil and air filters and tons of other parts..All 302 Z/28 engines, LT-1 of the 70's and and about 95% of all small blocks came from the Flint engine plant....Luke
