what engine is this for? I had a cvh34 ahmed in my old 1900 cvh, pulled really well, nearly as good as a standard cam but was still a bit lazy sub 4k, im pretty sure this cam was a low torque aimed cam at lows revs sort of cam meant for high air flowing engines such as zvh etc, ithink if you are talking about a cvh engine you have to make sacrifices, either a lower powered car with a nice spread of the available power threw the rev range or a higher powered car with the band spread over a few grand at the top of the rev range meaning you need to be sharp on the changes
