    low #'s after cam swap

    My friend swapped in an ms4 in his ss and when he strapped it on the dyno, he barley broke 360 whp?? I'm thinking its cuz he didnt degree it so is that a possibility? He has all the bolt one so idk wuts wrong. How long did it take u to degree your cam?

    You have an 01 witch generally dyno higher than the 98-00s. The ls6 intake helps.

    Hard for anyone to give a good opinion without any details at all...

    What kind of dyno?

    What transmission?

    If auto, is it high stall converter?

    Just those 3 variables can make a ton of difference.

    My full weight 2000 SS only made 344rwhp/314rwtq with cam and bolt-ons...

    But it runs 11.60's and pulls the driver's front wheel a few inches off the ground at every launch.

    BTW...
    Mine's an A4 car with 3600 stall and tuned/dynoed on a Mustang Dyno.

    did you pull the stock one out and put it back in and throw away the ms4? Thats some funny sh!t Dude I think your buddy put the cam upside down (180 out) or a really bad bogus tune.

    Put an MS4 in wrong and you'd have valves slapping like crazy. That cam is close in ptv clearance anyway so I highly doubt thats the case. Answer rels questions first and we can go from there. Mine dyno'd right at 349 to the wheels with a MS3, boltons, 3600 stall, through a 9" ford and my Tq converter was having lockup issues. Doesn't mean a manual car dynoing the same would be anywhere close to me in a race. It's not always about the dyno numbers.
