Yes it does, but only in the difference between a flywheel and a flexplate. Manual transmissions have a flywheel, that connects with the clutch from the manual tranny. The auto has a flexplate that the torque converter bolts directly to.
If the 351W has a flexplate, and you want to keep your manual tranny, all you have to do is find a 351W flywheel. They're available at any parts house, or used at a salvage yard (though I'd buy it new).
Be a good time to put a new clutch assembly in as well, since you'll already have it apart.

the 300, 302 and 351w all share the same transmission bolt patern and will all work together. the biggest thing is to know is that the flywheel can not be swaped from one or another. i believe 83 and down used a 28oz counter weight and 84 and up used a 50oz counter weight. the 300 did not use a country weight on the flywheel because it was internally balanced. hope i got this right. you will know when you go to start it. if its right or wroung. it will have the shacks and can scwer an engine up.

Look to make sure the 351w has a drilled hole in the back of the crankshaft(it should). Being it was on an automatic, it probably doesn't have the bushing or bearing that slides in. You need to install this bearing since it supports the tip of the manual tranny input shaft. It's called a pilot bushing or bearing.
You will also have to grind the motor frame perches off your truck, and get some v8 ones and bolt them in, so the rubber motor mounts will work.

thanks for all the advice. the reason im considering the swap is that whenever i hit a hill that needs a lot of gas to go over, the motor starts this really loud squealing-snapping sound and i can't figure out whats doing it. Any ideas?

The bolts that hold the carb together are famous for coming loose on these engines. I would take the carb off and have a look.
