Danr, might as well bite the bullet and get yourself a nice RAT MOTOR. There are plenty of them around, since they weren't so subject to putting their rods through the block thus needing sleeves. You could make tons of power without spending tons of money, even though you'd need new headers, a tranny adapter, and a few miscellaneous goodies. You would have to get another carb to feed the increase in horsepower and torque, but I saw a Prosystems 1000cfm carb on craigslist for only $550.
I'm just sayin...trying to help out a bud. What the hey, you've already got the Chevy Orange color...
