How much power can this handle? Obviously this is not a black and white question, but how much stronger is it and what kind of hp can it handle compared to a stock block?

    Boss 302 block M-6010-BOSS

    The boss 302 block is a great choice for reliable horsepower. As stated in the ford racing comments the boss block is ready to install with the exception of the final bore and hone. This block accepts all OE components, hyd roller lifter, etc. As mentioned in the ford racing comments the block will require new 1/2" special length head bolts/studs, a oil pump pick up stud which ford racing will supply free if you call them, a 1/2" to 1/4" npt adapter for the oil press sender, 4 - 3/8" lower timing cover bolts, special cam bearings J351 for standard cam journal cams and special head gaskets. The only downside to this block is the short cylinder wall depth which may be an issue for a 3.4" stroke crank depending on the piston but works great with a 3.25" stroke.

I always had a case of Hot Wheels with me, I would spend hours playing with them and then hours polishing and dusting them off, checking for any scratches. All my life my father would always tell stories about his 1968 Black Mustang that he purchased new...
