Yes, this 194/230 is installed in my 66 Nova. The stock camshaft needed replacement, and I happened to find that Clevite performance camshaft for 194/230/250 for cheaper than a stock cam. I paid $50 for the camshaft, and thought that was a good deal. Honestly I didn't really understand the numbers, and didn't do alot of research on it before I bought it. I did ask the guy where I bought it from if it would be okay for a street driver and he said yes, just with a little more performance.
I will try adjusting the timing as suggested in previous reply, and see if that helps. I think that'll still look for a 2 bbl carb to replace the current 1 bbl. The only thing I would be concerned with is overcarbing the engine.
