Who Makes Cams
faster ramps tend to wear out 'faster' as well.lol
cam choice should take head flow/flow ratio into consideration.imo
The 225 seems to take to the 100-106 centerlines in order to get them to rpm.ime if they are slouchy on the bottom cause you have a cam that doesnt turn till 3200 or whatever rpm, u might need more gear &/or convertor
