here's what I've got. Its a 638 casting from an '87 3/4ton pickup. Its only a 2-bolt main and will need to be bored out to .060 also. How radical can I build this? How much horse can this engine take until the bottom end disintigrates? I would really like to build this engine up into a 600 horse blown engine. Possibly a 383 stroker. I've heard that if everything is balanced, you should never have a problem. How true is this? Or should I just build a mild 350 and sell it to make some money? I've got the entire engine. Heads, crank, intake, everything.

Thanks in advance for all you're recs and opinions.
