My car weights 3200 with me in it.

The firing order are thge same.
Your B cam won't work in your 351w unless you convert it to a roller block like the 86-95 5.0 engines.
They will interchange if both blocks are non-roller blocks(pre-86)
In other words, they must both be "roller" blocks to interchange.
The heads will interchange but not wothout modifications to your 302 block. It must be drill out to accept the 1/2 bolts that are used on the 351w. The 302 heads use 7/16 bolts.

I'll let somone else explain the "M" motor cause I gotta go!
Hope this helps
