Leave the cam design to the experts That cam was designed by a true expert to run fine on the street.
It is a Ultradyne cam grind, but made by Lunati . Everything you have heard is BS. Promoted by people that have no clue what they are talking about.
When you set the lash on this cam set it cold .004" tighter than the hot lash spec.
( the lash opens up slightly when the motor warms up.
Shut the hood and drive it.
The advertized duration of a Lunati cam and a crane cam are measured at different specs. .006" VS .004" Hyd cams
You cannot compare the durations. between the two different specs.
This is a street mechanical cam. The "ramps" are designed for street use. And are not overly aggressive.
In fact if you bother to set the lash as I recomended you will be hard pressed to even tell it is in fact a solid lifter cam, when the motor is running.
(the slightly tighter "cold lash method" lash becomes the recomeded hot lash spec once warmed up)
Crane also sells a very very similar street mechanical also designed for the street along very very similar lines.
Look it up. ref: crane # 133841 and 131101 On a 108LSA. ( If you want a snotty agreesive midrange pull use this one.)
all these are street cams easy on the valvetrain just like the Lunati/Ultadyne design is.
Again the lift check spec of the adv durations are not the same. These cams are more alike than different when actually measured with the same spec.
Thanx for the info, sorry about the mix up on your cam suggestion,I thought you were referring to a 60202 voodoo cam,my mistake(I don't have these numbers memorized yet) which takes a much heavier spring than the crane cam I'm using ,its the heavier springs that wear everything out quicker,although its nice to have that extra protection I don't need it with my planned 5500 redline(even if the motor pulls to 6000 or beyond) You probably haven't read my other entries here but I don't plan on racing this motor so a solid cam is certainly not in the planning (I don't like having to adjust valves anymore than I have to) and although your suggested cam is a powerhouse for sure its a bit beyond my horsepower needs. Once you go beyond that magical 500 HP you open up a whole other can of worms like new tranny's,driveshafts ,rear ends,frame connectors,bigger brakes,four link rear suspension set ups,tubbing for traction,I don't want to go crazy,just have some laughs with the car(although I'd go crazy if I could afford to) but thanks for the technical on the valve seat placement,certainly something to think about while I'm busy with it.
