anybody heard of Traco engines befor????? the front drivers side of my 350 block on the id plate is stamped with a vin#V02126WK than right under that is two stamps like little ovals that say traco in them, than on top of it all it says s.s.350.001.. on the back of the block drivers side it gives the block id# 3970010...just kinda wondering what the block is. the pistons say .30 over on them and the bore is very little over 4" the storke is like 3.75 or so just kinda odd any help would be great thanks guys.......justin

The s.s.350.001 is a machine shop stamp. they put that on when it was rebuilt.

the 3970010 is a 350 block cast from 68-79. Applications ranged from 160 hp to 370 hp vettes.

Your particular engine code was stamped on feb 12th in the flint michigan plant.

the last 2-3 letters which in your case is WK. WK denotes a 1969, 255 hp 4 barrel truck engine. anywhere from half to 1 ton. This probably means its a 4 bolt block.

its strange though because the 6 in the number shouldnt be there. Make sure the 6 isnt a letter. if its a letter it will affect what it codes to.

heres how it brakes down. (examples)

Engine ID Code Example: V0101CLJ - (V = Plant, 01 = Month, 01 = Day, CLJ = Engine Suffix Code)
Another example: T0830CTY - (T = Tonawanda, 08 = August, 30 = 30th day, CTY = 1970 396 Camaro, 375 hp, 11.0:1, TH400)

Code Engine Plant Code Engine Plant
F Flint (Motor) S Saginaw Service
H Hydramatic T Tonawanda
K St. Catherines, Ontario V Flint (Engine)
(McKinnon Industries Canada)
M GM of Mexico


by that, your engine is 02 (feb) 12 (12th day) then 6WK either the 6 is a letter and you misread it or just the WK matters. and its what I said above about the truck engine.

**NOTE** measure your stroke again. if its a true 3.75" stroke you have a 383 stroker motor, not a 350. stock stroke on 350's are 3.48". a 400 sbc has a stroke of 3.75 and that crank in a 350 block with a .030 bore is 383.

well i now i read all the numbers right and it is a 6, thanks for the help...justin
