Cam Choice
 

Im not really sure what type of cam choice to go with for road racing. Or what specs to look for when buying a cam for this type of application. Any help or comments is appreciated. Thanks!

Car type and other mods will help.

If your sig is right.....2002 Z06.

Typically you are not going to go with something that is very radical as far as the cam profile goes because you are going to be seeing higher RPM's for longer periods of time as apposed to say a drag racer.

For C5's one of our most popular selections has been the G5X3 on a 112. Gives you a great power band from 3000-6800 RPM where you are going to be most of the time on track. They are radical enough that the car makes good top end and had a great sound but not so radical you can not drive it to work and back either.

It should be used with a good set of long tube headers and cold air induction.

Typically speaking these cars should make about 425-435 rwhp on a Dynojet SAE corrected with headers/cai/g5x3 setup.

You are always at wot pretty much so I wouldn't be concerned about street manners. Just keep the lift to or below .600. I prefer smaller and medium sized cams. I like the power to come on sooner than making an extra 7 hp between 6400 and 6500 rpm.

:iagree: That is what I am running. Have seen 440 with AFR heads, now 418 with 243 heads. However, with a clutch pac without flywheel you will find the engine is in constant hunt for idle making DD a little trying; with a flywheel - no problem.

I have a 2003 Z06 and got a PatG specced cam. I mentioned road course use and reliability was pretty important to me. End result was an EPS 226/230 .605/.605 113 +3. Running high quality beehive springs. Makes power all the way to 7k, overall been very happy with this setup-- made 435whp/405tq.

You have a sheet metal intake?

Stock LS6. I got my 243 heads ported by AI (226cc program) at the same time. Email/remote tune- so there may be some more power on the table but I haven't bothered with that yet. Been happy with it and the overall power curve. Dyno below- before is LS6 with headers/x-pipe/tune/air intake- made the standard 390whp. Same dyno- I have the actual dynojet run files, but I put the numbers into excel, as the rpm was cutting out at high rpm and it makes torque readout wonky.

Lighter clutches can make it a bit harder to drive around town and can take some work with the tune to keep them stable. That would be true of about any bigger cam and light clutch combo though.

I would start with who is going to tune it and get his recommendations. It needs to be something he is comfortable messing with.
