So does anyone have a Thumper cam in use???
Cam selection takes so many other things into consideration.... what's the rest of your engine, SCR, DCR, usage, valve sizes, port sizes, etc, etc, etc.?>???????

The only way it would matter how someone else's use of a specific cam worked out for them is if your engine were identical in every detail.....

BTW, the opinions expressed on this thread come from countless years of experience making cars go fast......
