351 what?
I bought a 75 F100 about a month ago and I'm still not sure what 351 engine is in it. The guy I bought it from thought it had come from a 74 LTD but wasn't sure. There is a M on the front of the drivers side cyl head. Does this mean it's a modified?He also said the tranny was a C-6 if that matters.

The only way to tell the difference between the W 351 and the M 351 is the M 351 has 8 valve cover bolts, while the 351W has only 6.
I think also the thermostat housing bolts on top of the intake, instead of the front of it, like a 302 or 351W would.

351M and 400 heads are identical.
I suppose since the 400 came first they should all be called 400 M heads, but they are also nearly identical to 2V Cleveland heads, so maybe they should be called C heads.

Well I guess I have a 351 modified. This truck is my first project in a really long time but I'm really exited about it. Is there any way I can find out what year the motor came out an what would ya'll suggest I do to it. I'll just drive it to work an back but would like to maybe show it if I ever get it like I want it. Thanks for all your help.

no, you have 351M. the M doesn't stand for anything
to find out what year it is, post the part number or the 4 digit date code thats next to the oil press. sender.
it looks like this

with the part number i can tell you what it came from and when it was introduced.
With the date code i can tell you what year, month, and day it was made.
