I pulled a engine code from a 1971 442 which I would need some help with if possible. The block numbers are 396021 with 68F4 stamped inside the back of the block. The stamping on the machined surface below the head drivers side was 39F118315. This number was hard to see so I may have this not exactly correct but close. The heads had a big raised C on them in the usual spot. I did not pick up the casting code on the heads. The crank is a N crank BZ CFD. The motor was painted Red which I believe is the original Color as it is in pieces on the floor. The car vin is 344871M 01550. I am confused by the Year One explanation. The car has not ran since 1976. Any help decifering would be appreciated. It also has a cast iron intake.

That should be a 455 originally out of a big body '69. C heads are correct for that too.

1971 442 should have G heads and paint color blue metallic

As noted, it's a 1969 motor. Check the stamping again, however. The letter F would indicate the Flint, MI assembly plant, used by Chevy. No Oldsmobiles were built there. I suspect that letter is either an E (Linden, NJ) or an R (Arlington, TX), which were Olds plants.

i will go out and check but i think i have one with an F in the vin stamp.

jensenracing77

after looking at it i am sure that you are right. all the numbers are crisp but the F it is not stamped as well and may be an E. it sure looks like an F though.

So we are talking a non original motor out of a 69 car which is not a Cutlass supreme body style. How many horse power on this motor? The car I was thinking of purchasing was used for drag racing i think. the motor is all over this guys garage in pieces. The car is in ok shape considering it is a rust belt car Michigan driven. The floors are very nice. Seems the rear part of the frame behind the wheels is a little shaky. The car needs a front fender, rear trunk lid, new bumpers,new grills, patches over the drivers side wheel well . The guy wants 2K and will take nothing less.

No rust around either front or back winshield

sounds like a nice deal if the parts you list are in good shape.

jensenracing77

what kind of shifter in the console?

tim72

Thats the first thing I looked at was the shifter and it is not a hurst.
If this guy raced I can almost bet he hit neutral at some point and blew it up. I just bought one for my 72 supreme. I am not going to take the chance with a 500hp motor.

Can you tell me what the last 6 digits 118315 would possibly pertain too? I mean was the motor out of a 98 or a 442? Also how can I tell if these C heads have the big valves except for measuring them? Seems the big valve C heads are the best flowing olds heads. I wouldn't mind doing a simple rebuild and draging the car for fun.

118315 is the VIN derivative (last 6 digits) of the car it came out of. You'll have to measure the valves to see which ones they are.

118315 is the last part of the VIN of the car it came out of. It came out of an 88 or 98. No F85/Cutlass/442 455s in '69.

Again, the "F" was used to designate the Chevy plant at Flint, MI (as opposed to "H" for the Buick plant at Flint). NO Oldsmobiles were built at that plant, so no 455s would have come with the letter F in the VIN derivative.
