|  I can't remember where, but I saw a dyno number on ported E7's that showed a 23 HP increase over stock. Not sure on the intake though. There is an article in MM&FF this month that talks about the stock intake. I just can't remember any of the numbers they had pulled. |

| My car have 249 rwhp and 312rwtq. My upper is slightly ported ( i've only ported what was accessible with my die grinder). This spring, i will add longtube with x-pipe and maybe an extruded hone upper. I hope that those mods will gave me 10rwhp. My heads have the stock valves with hi lift spring. My car is speed density so maybe 5-7 rwhp less with mass-air (maybe more, but not sure)

| The only way to fully port a stock upper is with extrude honing or cut it in half, either way, the cost would be the same as a Cobra intake, which with long/short runners would be better than the ported stocker. I'm not going to comment on the E7's, because i always get slammed.

| the stock intake will flow pretty well if you know what do do..the lower intake is the restrickion..open that up or buy a holly systemmax 1 lower intake..then you can have the upper extrude honed if you wish..every bit helps to give you an idea of how our "stock" appearing car(the money maker  ) does..try high 12's on a all season tire..it still has a stock intake/massair/tb..only mods to car are ederbrock heads,b-303,3.73's, full exhaust..car goes mid 11's on slicks and 125shot..so there is hope in the stock intake the way it sits..altough most people will tell you otherwise i suggest getting heads b4 you buy a intake
