the walkinshaw w407 is a great street cam for a auto or manual, i think it was ground for walkinshaw by camtech which have now closed but most camshaft grinders have a similar grind, specs are 222in-228ex at .50, lift is .585in-.591ex with 116lsa
walkinshaw tested half a dozen grinds for there w407 NA and w547 subercharged packages and chose the above grind
its only a small cam but has a nice lobey idle note and rocks the car gently at the traffic lights
matched with correct beehive springs its also easy on the valve train not being over 600thou lift
you can drive it everyday mines a manual and only fault i can say thats very minor is a low speed snatch but its hardly noticeable
its always better to go a smaller cam than a big one on the street
any cam around those specs will work great , compcams, crane, isky, vcm ect should have something close
good luck mate, make sure to do exhaust , intake ect to enhance the power
