How street able are these 340 stroker motors?

Is it cheaper to buy a kit or buy the parts seperatly?
I priced out the steel crank from dodge - $1000.00.
Whats the best choice for rods and pistons? hoping the block cleans up at .040. Can I use stock rods ?
Pulling the motor Friday night!

I used a cast Scat rotating balanced assembly I bought from Brian at IMM Engines. Everything measured spot on. Brian could have sold me a unbalanced kit and then charged me to balance it, but he said he has checked them and they were fine for my street/strip application.

Cast is fine for street strip car around 500 HP or less. Got about 6,000 hard miles on it so far.
