HP increase?? 355 sbc heads/cam/intake upgrade????
I have a sbc 350 (355) with forged srp pistons, pink rods, gm crank, etc., and have put on a set of AFR 180 heads, lunati voodoo 60103 cam w/ 1.6 rockers for a bit more lift, Edelbrock performer Air Gap intake, Coan 2800 stall converter, and a 3.42 gear, Holley street avenger 670 carb, and a built 350 trans. the car runs GREAT. Has lots of power down low and really pulls hard up to the top. I'm guessing it probalblly runs high 12's or low 13's in the 1/4 mile. I originally built this car/set up for a good street cruiser, which it is, but I really want some more power, and think it is a very tame car to drive and is VERY streetable...
Here's what I'm thinking about doing.
-having the heads and intake worked, ported/polished, by a great well known performance shop, stepping up to a bigger cam (voodoo)60104, upgrading my converter to a 3400.
What hp increace do you thing I will see?? What 1/4 mile time increace should I expect (even though I haven't ran the car yet)
to me, this car is VERY streetable, and I want to keep it that way, but don't mind a bit more of a WILD street setup.
HP guesses now/after??????
