New motor
I have a 86 iroc-z and it only has 55000 original miles. The 305 is nice but I would like more power. What do you suggest? I was thinkin a new motor. It's gonna be a daily driver

Daily driver without insane power? Just get a GM crate engine for around 1500 - 2000 and you get a warranty with it usually. They're not bad engines and I think the low end one's rated at 250hp.

Thanks. I was thinkin about buying a bare block and building it myself for the experience. I'm gonna be working on it little by little so price isn't gonna be a big factor. I was thinking about maybe a 350 or 383 stroked. Any suggestions on parts I should use?

Well if you don't have to have it right away then that's a good way to go. Make sure you plan out what you want first as I know the bug to just buy stuff and start slapping it together for someone just starting out can be a tough one to fight. 
If you want a good all around engine then go with the 383 over the 350 in my opinion. Make sure you do the research on that before you dive into it. Especially if you're going to be tackling the grunt work yourself. Read about what needs to be clearanced, type of cams and how they affect compression, heads and how they affect horsepower and torque, etc. Talk with people around and find out who is a reputable machine shop that can clearance the block for you and will do a great job. Ask them A LOT of questions. There's a lot of kits out there and some good deals on them for a 383. If you're not planning on going high compression with power adders than a standard cast crank and rods would be fine. If you plan on making tremendous horse power with high compression (both SCR and DCR) and power adders then I would suggest a forged rotating assembly. Summit or Jegs has a 500 hp 383 stroker pre-built by Patriot Performance for 3800 bucks if I remember correctly minus carb, dist, and a few other things. If you buy it fully dressed I think it's 5k and it's a drop-in-and-go setup. Buuuut, I've never had anything by Patriot and I know some people consider them low end.
Do it the way you want it the first time because otherwise you'll be kicking yourself for not doing what you really wanted after it's done.
