This Lunati cam is very close to the one you all ready had picked out,either cam would be fine,as would the comp unit.I tend to use a little bigger cam in my motors,pull hard all the way to 6500.Had to same motor in my car for several years,drag race only,and ran a hyd roller cam with edelbrock 290 cc heads and it pulled good to 6800 every weekend for four years.Its now a 540ci.If you run on the street more than the track you may want to go with the smaller cam,3400 lbs with a street tune smaller cam may have better manners.
