302w vs 351w
So I have just inherited my dads high school truck which was a 1979 f150 and I'm going to be rebuilding the truck but the 351 m that is in it is completely seised and so is the transmission so I want to throw in a 302w or 351w in it and I will probably be stroking the engines in the future so I want to know which engine I will get more power out of for a reasonably price

Gonna be easier and require a lot less work if 4wd going back with a 351M or 400 base.
If 2wd, it'll be a bit of searching brackets, etc, but will be easier connecting a driveline.

Both are popular engines, but there is no replacement for displacement in my opinion. Go for the 351W. I'd look for a later production roller block too, capable of a heck of a lot of power. I've got one sitting in the pile-O-crap waiting for a rebuild to got into the Platypus truck someday.
Motor mounts / tower for 2wd small block.

If you do YouTube, look up Neomustangs. Guy does a lot 302 / 351w builds for fox bodies. Has a ton of useful information.

If I wanted cubic inches I would do a 460!! All day everyday!! They are making quality heads and stroker kits and good roller cams.
for a daily driver or a weekend cruiser I would do a factory roller 302! Cheap…parts galore…lighter weight/smaller package size in the engine bay. I would stroke it to a 331, AFR heads and a “rv” smaller duration/lift cam and you would be putting down 350+ hp…way more hp and TQ than any era OEM option for that truck.
I’ve built a few of them and they are strong little engine. The one in my mustang is about 460hp, revs to 6,500 and is almost to much for a 3,000 pound street car. The other one makes about 340hp but it has the power band way low for a bronco, still makes power all the way to 5,400.

Yea,,back in the day, what we called the 302 HI PO was quite the deal. Great race engine with high RPM and power.
