Jim,
First and foremost, listen to Don. He IS the small block guru. Second. I can gurantee you a minimum of 25% increase in horsepower if you have the stock exhaust pipes, and it looks like you do. Simply change out the 'bullets'. I couldn't be more serious and the sound is awesome. The simplest and cheapest bang for the buck!

Put that puppy on a dyno and get the true RWHP and torque rating. Change the pipes and do it again. 25% minimum increase-guaranteed!

Then the old MSD box (6AL) will do wonders. Then if you're really feeling frisky, change the distributor over too. You are running a carb'd engine, no?
