Really Good Idea
I have a 77 F250 Highboy with a 351m and a 4 speed. When I rebuild the motor this is my idea: 434 stroker, edelbrock performer rpm heads, roller cam (not sure on exact one yet), 6-71 BDS blower, efi, and a pertronix multifire ignition system. I'm looking for 600-650 horse or so. What do you think? Any other ideas?

Nice, I would go with CHi (Cylinder head innovations) 3v or 4v heads (ask Tim Meyer tmeyerinc.com). You could also ask danlee (member here) or Tim Meyer for danlees specs on a custom roller cam he designed for his 434. Im running a simmilar spec roller cam on my 408...
You will also need plates to use a nice single plane 4v or 3v intake manifold.

You are going a step too far with a blower. Your stroker motor could be good for 500 horse, which is more than your drivetrain will digest for very long anyway.
"3v and 4v" heads? Read it again.

Chi heads as i remembered back when i ordered my 3vs they had 3 variations, and yep i was right:
Cylinder Heads Ford
he could achieve 600 NA with the huge heads and a big cam, but 500 and 550 lbs of tq is alot to me... and more street friendly

I'm thinking the blower is perfect for what I am looking for. It will let me build a slightly less mild motor that will be drivable but also have 600 ponies.

I have thought about that or dropping in a hot rod fe of some kind but everyone and there brother has one of those in their highboy and I've never seen one with a blower sticking through the hood so I feel like this is a good combo.

The 351m needs some serious work to make any power at all. The low end build is a cam, plus a 4bbl manifold and maybe headers. The cam is really weak, so just about anything else you do is just noise due to the cam and low compression. Once you are beyond that, you need to make a 400 out of it and add compression.
