[QUOTE="tt335ci03cobra, post: 16087242, member: 68944"] The more I read on cam specs, the more I am finding that that cam spec is not ideal for a street car. It should make excellent power from 6000-8000rpm+ though I’m running a 3.73 and 26” tire. I think if I had a 3.27 and a 28” tire, mine wouldn’t have enough low end grunt for daily driving. My stage 3 mmr grind feels like it loves 4500-7000. It makes good power after 7k and ok power below 3k. My sacrifice point is from idle to 2500. Car still has ~300wtq down there but it pales by 3k and up is when it goes 400-700wtq. Turbo car so spool etc. I have to brake boost at 2500 to get a lot of spool/torque if I want to to pull very hard from 3k. That creates metric tons of crank case pressure so obviously I don’t. My cams are about 25-33% milder than what you have, and they were a bit of a bitch to degree for street driving but not horrible. If you sold those heads and cams for a set of worked over 4v c heads with a strong stage 2 cam in them, or medium stage 3 blower cam, I think you would end up with a much happier street car. Do you mainly drive in the city/freeway or is it a weekend racer? [/QUOTE]
