351M and 400's were the most popular engines in the bronco's. Unless a swap was done it's definately a 351M. A swap would be very costly and involve a lot of work. you could tell by looking at the frame near the mounts and see if they were changed but i really doubt it.... The Windsor never came factory in Trucks.

351-400Ms were the only optional engines, and they look so alike it could be a 400, but if the engines never been out of it, go by the stickers or vin.
Ford started fasing in the 351w in about 82-83, they used the 351M stock up before using the windsor.
For 800 bucks, I say jump on it.
That is an easy swap from the 351M to a 400M

yeah I got a 750 edlebrock I know is too big but thats what I got I figured the 400 with a good cam and that carb should do pretty good in that bronco then looks like Summitracing carrys some cheap headers for under 100 bucks and throw some 2 1/2 duals with glass packs and it would make a great trail rig what you guys think it got stock size tire looks like but it has the old style slotted mags looks okay.

It probably is a 351 or 400 M. Someone said the windsor never came factory in the broncos. The windsor did come factory in trucks. Thats what all the 80-96 trucks had. I could be wrong on the exact years, but I know our 85 has a 351 windsor. My 95 has a 302 which is a windsor motor. I am not sure what year it changed.

The 351w was not an option in 78-79 broncos or trucks, but they replaced the M blocks in 1980-83.
Also, it's a common mistake that the 302 is a windsor block, but is not.
The 351w got it's name because of the foundery it was cast in and to also, to distinguish it from the other 2 351 blocks
