265, 283 and 327 SBC motors are all have more HP than the 350 and the 283 and 327 make more torque.

The L-48 is the original 350 cu in (5.7 L), available only in the Camaro or Chevy II/Nova in '67 & '68. In '69 it was used in almost everything; Camaros, Corvettes, Impalas, El caminos ,Chevelles & Novas. From '75-'80 it was available only in the Corvette. L-48's use a Hyd Cam, 4bbl Qjet, Cast pistons, 2 bolt main caps, "Pink" Rods, #0014 Blocks & #993 heads. Power output ranges from 300HP(gross) down to 175HP(net).

Well there you go, it could be a 67 but then it wouldnt be a chevelle.

Wow thats ugly.

Engine Code Stamping Numbers
All engines are stamped with an engine ID code, consisting of assembly plant code, production date and suffix code. V8 codes are stamped on a pad just forward of the right side (passenger) cylinder head. 6 cylinder engines are stamped on the passenger side of the block behind the distributor

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

according to this http://www.chuckschevytruckpages.com/casting.html

I did find my casting number. It is 3970010

which according to that page is either:

3970010 - 302 1969 Camaro Z/28 - 4 bolt main bearings
3970010 - 327 1969 2 bolt main bearings - trucks
3970010 - 350 1969 - 80 2 or 4 bolt main bearings

Also I Just Called the Previous Owner Stating that it was a "1976" Chevelle 350 Engine.....Must have gotten the numbers mixed...lol...idk but i think i do know now for sure its a 76 chevelle 350..
