Planning to build a Marine 383 Stroker

Greetings to all, just signed up and hoping to learn a lot.

I recently blew a rod bearing in my stock '88 5.7L/260 HP. Since the crank is pretty chewed up (-.050 on the one rod) I'm hoping to buy a balanced 383 stroker kit and gain some much needed HP. Seems to be lots of considerations for components and it's making my head spin. I still have a good 2-bolt block and stock heads to work with. (Engine code=V03168AB, which as I have been able to decypher as built in Flint on May 16/1988, Air Brake. Must be a generic light duty truck block).

I'm looking (I think) for the main power curve in the range of 2000-4800 RPM, which is everything from getting out of the hole to rated cruising speed. Previously, 3000 RPM was barely minimum to stay on plane and 3500-4000 was nominal cruising and definately with the secondaries almost fully engaged. Anything faster than 4800 will just burn my drive up. This isn't going to be experiencing any kind rough throttle handling either, it's a comfy express cruiser which was under powered by 100 HP from day 1. I don't mind a bit of rough idle if I use a perf cam, but not too much as this might play games with my outdrive gears/clutch.

I would like to keep the cost contained to $4K Can, taxes and all. Any suggestions how I should approach this so that I can get that needed HP and have a reliable setup?
