Engine size help

[jhill51]

I'm a Bronco newbie...converting from Jeeps. Bought a '79 Ranger XLT edition that's in decent shape. I can't tell if it has a 351M or 400M in it. Does anyone have a VIN decoder or know of a website?

Thanks,

-Jhill

If it's the orginal motor chances are it a 351M.

Look for the emissions tag on the hood or drivers valve cover. The only other way to tell visually is to pull the oil pan and look at the casting # on the crank. The only difference is the crank and the pistons. The rest of the parts are the same for both motors.
