It will not be an easy task to build a 500hp small block and keep good street manners. You should consider a big block before you start planning. JMO.

Any suggestions for a good 350 build ?

You can make 450 with a stroked/bored 350 without too much difficulty. But to do 500 gets that much more difficult.
I'd do a 380 stroker with really good heads etc. You'll make 450 with that combo and still be streetable. You'll lose streetability from there as you go up in hp unless you further increase the c.i.

Sure, start with a 455 and after that is easy to achieve your goal.

I'll ask the same question I ask every time this comes up. How much money are you prepared to spend on the engine and how much more are you willing to spend on the rest of the drivetrain behind this new engine?
