CAMQUEST - Can I substitute Big Block CI for Stroker SB?

http://www.camquest.com/

As you most already know, Camquest allows you to input certain engine variables to provide a camshaft suggestion and the rough dyno numbers thereof.

Camquest is far from perfect, but still somewhat helpful.

A big down-side to me is it's lack of engine options; it only provides factory engine displacement and strokers aren't taken into consideration.

To get down to it, would it be at all accurate too substitue a big block 383 for a 318-based 392 stroker in Camquest?

383 BB = 4.25 Bore X 3.38 Stroke
392 SB = 3.94 Bore X 4.00 Stroke

Comp recommended me a cam for a 392 build that I am having trouble accepting as the 'best choice', so I started messing around in Camquest with little choice but to use the 383 as the platform.

My concern is that, although close in cubic inch displacement, there would be a real-life difference in hp and torque. The bore on the '383 BB' is bigger and so are the valve-size options, but the '392 SB' has a bigger stroke (in terms of swing).

For example: Would the same cam for both engines make more horsepower in the '383 BB', but have greater torque in the '392 SB' ?

Can I safely use the 383 numbers in my cam choice or are these motors waaay too different of animals to be comparing?

And, VERY IMPORTANTLY, can I assume power bands are similar between the two engines with the same cam?

Thanks!
