Camshaft change

[SMCBUILDERSINC]

I have been considering a camshaft change in my viper. I was wondering if it was a difficult task for a DIY install? Ive changed many cams in Chevys through the years and was wondering if anyone could fill me in on the basics? For instance, does the intake need to be removed?

I currently have ported heads and intake, a custom cam but I dont know what size it is, T&D rockers, 1 3/4 headers, Hi flow cats and 3 inch pipes, Aluminum flywheel and carbon fiber airbox. Ive put 507hp and 525tq before the VEC1 and 526hp and 545tq at the wheels after the VEC1. I want to be around 550 -580 at the wheels and I want the motor to be N/A.

So, that being said, what type and size of cam would be acceptable? I am not interested in haveing a car thats not drivable.

Sound's like someone already made the cam choice. They probably picked the right one from the sound of your numbers. I'd leave it as it is.
I don't see how you could get to the lifters without removing the intake, even on a Chevy.

On a chevy you have to remove the intake because the lifters are in the oil galley. The v10 doesnt have an oil galley like a chevy engine.

One more thought,
I think that I could choose a more aggressive cam then whats in the car already. Theres always room for improvement.

Not only do you have to remove the intake you also have to remove the Heads,radiator,a/c condenser and also insure that you are up on your cam dialing in techniques,IMHO,,if you already have an upgraded cam,to get the kind of #s you are looking for and not loose low end driveability by only changing cam you are going to be dissappointed as it will not happen unless you raise your compression via milling.chances are pretty good that if person that did the work on your motor went as far as heads and cam they most likely researched which cam profile would best suit the build.
