Do Hot Cams make a big difference in power? What stage hot cams should I buy 1 2 3 ? Do They hurt the engine at all and is there any other parts you have to buy also ? .Ive done the cam mode rejetted the carb. dr. D exhaust did the carberator throttle mod were you put a small rubber band around the throttle linkage and I want to go faster with out spending to much cash please help or give me some ideas  

Come on give me some input some ideas......  

if you haven't bored the cylinder out then i would go with stage1 hot cams they will make a difference.

boring the engine pound for pound will go alot further.
than just adding the hot cams.

if you bored it out and added the cams you'd see a huge difference in horsepower.  

Not a big fan of Hotcams. I much prefer web cams.

Cams are not cheap though. What kind of intake you running?
