Chevy engine blocks origin ?

[Greg Reimer 7376]

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

The Target master I am disassembling was dated '89. The block,crank,heads and pistons all marked Mexico. It was purchased about 1989 or 1990 installed briefly and then involved in an accident (write off). I am not sure of the mileage but so far it looks really clean and decent inside. Owner was a Valvoline diehard. I did notice the crank casting looks very rough and the finish almost appears as if a coarse wire wheel was used on counterweight flash.
(4 bolt main, cast crank, cast dished pistons, 993 heads, single link timing chain...)
