How are you liking that combo? I really think you should be making more hp with a cam that big.
So far im liking the combo and with the proper tune now its very streetable, occasionally it surges a little bit if i step on the gas and then have to break real quick it might surge a little for a second or two but thats probably more related to the big throttle body. as far as horsepower goes im happy with it. dyno numbers are all subjective it all depends on the kind of dyno and i guess load put on the rollers, and im sure we could have tached the engine up to 7000 rpm and gotten a little more out of it and tuned it a little different for a race set up and loose more streetable characteristics.

you should also look at upgrading fuel pump and will need to upgrade injectors, and those 3.73 gears should be spot on thats the kind of gears im looking at putting in if you want any more specific info on my setup just pm me ill be happy to share

I think the PRC 227 and MS3 or MS4 combo will work well. And both of those cams will appreciate the SS4000 when paired with 3:73s. You will have no problems hitting mid 11's and possible lower 11's depending on track/weather/car weight and all those factors.
No i have not had a chance to run at the track yet but i would assume it would run some where in the 11's
i think the PRC 227 might be better also but paired with the ms3 or ms4 i think you have to fly cut pistons with those heads
