help me to understand cams

Cam selection can be critical or general. It all depends on what your after. The 440 Rat Rod, just by the title of it, sounds like cam selection is less critical.

The s/b 408, what are you doing with it?

the 408 is just going to be toy, hit the streets, and track i doubt if the car will see 2000 miles a year Im looking for a very healthy very nasty sounding sb. the car is a 4spd and im not too worried about street manners as most of my cars dont have much for those. I love th sound of the thumpr cams but there performance is terrible, id like to have my cake and eat it too.
