Not worth worrying about. Stock Muncie's will take more than you can afford to build. Rear end too. I say that because it costs alot of money to make serious power. So unless someone dies and leaves you a buttload of money that you want to throw away into your car...forget about it. Buy a block cheap, buy the best parts you can get cheap and build it yourself and you'll still be into it for $3-$5K. That'll be a mild build. Maybe around 350HP if your real lucky.
