If you're looking for low end grunt, Comp cams has one for the 194-292 inline that should work real well. I think they call it a 260H or something like that. What you want in a cam is moderate duration and a lot of lift. Basic rule of thumb with cams is that lift will give you torque, and duration gets you horsepower in the upper rpm range. Don't get too crazy with carburetion, one small 4 bbl should be plenty. The MAIN thing you're going to need is a better exhaust system. Stock Chevy inline exhaust manifolds don't breathe. At all. Nada. You probably should run Tom Langdon's cast iron headers or Clifford headers, or the rest of the things you do aren't going to make a whole lot of difference in absolute power output. Chevy sixes are torque monsters if you let them breathe, but if you don't, they're pretty much meek little lambs as far as power output goes. And either the Offy or Clifford manifolds will work for what you want. Hope this helps some. Might be a good idea to pick up a copy of Leo Santucci's Six Cylinder Power Manual, too. Lots of good info in it.
