The M in your VIN indicates 351 Windsor 4bbl. The 351 Cleveland did not come out until 1970.
1969 with 351 Cleveland 4v
So I recently got 1969 mustang and the guy that sold it to me didnt know what engine it had.
So I figured its a Cleveland 8 bolts radiator hose connects to the top and vin said 351c
I looked up the Vin 9r01m126646 and it said 351c but im reading forums saying there is no such thing as a 1969 351c 4v so im so confused.
or could it be a 351m
how can I find out?
Im trying to get new rocker arms and i cant till i find out what I have.

It cant be a windsor though has nothing looking like a windsorThe M in your VIN indicates 351 Windsor 4bbl. The 351 Cleveland did not come out until 1970.
Quickz, This is a confusing issue. Commonly accepted knowledge indicates that there was no "Cleveland" 351ci engine in the '69 Mustangs. Two things (in my opinion) might argue for a '69 351C. First is a number of references to the '69 Cleveland in Mustang reference books. Some specify vin code M as Cleveland, most simply do not refer to either/or; just M-code as a351-4V. Second is the knowledge that Ford was preparing the Boss 302 for release, which we all know had "Cleveland" heads on a "Windsor" 302. So if the heads were available, how can anyone believe that a few 351C-4V '69 Mach Is aren't running around?
The 351M was not a factor until '75. Again, this is my opinion only, and I am sure there are other members that can reply to your inquiry also.

If it has a Cleveland in it now someone other then Ford Motor Company put it there.
Take the valve covers off and look at the valve springs. The Cleveland had canted valves, the intakes and exhaust valves were at different angles. The Windsor's valves were all at the same angle. The Cleveland looks like a big block brand X to me, and does not look anything like a Windsor.
Not sure what "The 351M was not a factor until '75…" means, but for whatever it's worth, I had a '73 Torino with a 351 Cleveland in it. It was clearly labeled as that by Ford when I ordered the car.
There many differences in the way a cleveland and windsor look, so here are some of them:
1. The coolant outlet on a windsor is on the end of the intake, on a cleveland it is on the top of the front of the block.
2. The valve covers on a windsor have 5 bolts, the cleveland has 8 bolts.
3. The timing cover on the windsor is aluminum, on the cleveland is thin steel.
The simplest thing would be to post some actual pictures of your engine, and we can then tell you what you have. And lastly the cleveland 4V had massive intake ports like the boss 302. And someone could have changed the engine at some point, so it could have any of the ford engines even a modular one, or any other make (chevrolet, dodge, etc) engine if the they were good enough at installing. Good luck.
