|What do you want out of this camshaft? Is your car used in traffic, or just played in on the weekends? Where do you want your power located...low or high in the rpm band?|
An Autotech 270 or a Techtonics 266 (different advertised durations, but basically the same characteristics) is going to give you a lot of torque low end, but not so much up top. This is a good 'around the town' cam if you arent into racing or revving the crap out of the engine between shifts. This cam has a decent idle as well.
A 268' camshaft is the best overall camshaft for everyday driving. great low end torque, and it will pull till about 5200rpms strong. Techtonics makes one for $130. I ran this cam and liked it a lot. It has a lobe center of 110'...which gives it a lopey idle. Schrick and Eurospec Sport also make a great 268 as well, but you will pay a premium price for either of them. Also, they have a lobe center of 113 degrees, which would make them an ideal "larger" camshaft option if you wanted to go forced inducted later.
A 272 duration cam is the largest duration you want to go with a stock head. I currently run a 272 and like it a lot. It starts to pull strong after 3500rpms till 6400rpms. My stock head limits me from the engine breating well after that rpm. This cam is also great on the highway....when needed, 5th to 3rd drops are VERY fun!
One more thing, you will need to replace your single valve springs with a dual spring setup when you upgrade your camshaft. No if, ands, or buts. I didnt put dual springs in my head right away and ran two separate cams with lifts of .440" & .444". When I finally did upgrade the springs, the first two coils of the springs were silver where you could see where the spring was binding! Max camshaft lift on stock OBDII valve springs is .428". You can purchase HD spings from Techtonics (their springs are fine now, despite their past problems) for $120 or you can get more expensive ones from Autotech or Schrick.
