I'm building a 461 stroker since I just blew up mine. I'm wanting a comp cam and I want the performance with the traditional muscle car sound. I'm looking for a solid loping cam.

This has been discussed many times. It is just not that easy. A number of specs have to be hammered out first before you actually choose the cam. The cam should be one of the last things you select. You can get that rumpty-rump muscle car cam idle and have a dog for an engine. The rumpty-rump usually means a lot of valve overlap which in turn means a fairly high RPM running engine at the sacrifice of low speed operation which is what you will be mostly cruising in.
What RPM do you plan to spin? What horsepower/torque range do you want - lower,middle,upper? Do you have the compatible parts to spin at your desired RPM? What is your actual compression ration? Do you want any gas mileage out of it? What type of heads -aluminum/cast iron? What kind of CFM flow numbers do you have? What type intake/carb? Headers, factory manifolds, duals -what size? Transmission type? Converter stall? Flash stall? Rear end ratio? Tire size?
Not as simple as it sounds in picking a cam -parts have to match one another. And, you can have great numbers on a dyno, but have a slug once you install it and the "real world" takes over. Always build for good torque numbers with a Pontiac. Pontiac has its own unique sound and it really doesn't have that rumpty-rump sound a chevy can have because they can RPM way higher -this is why you always know its a Pontiac just from its sound.
As suggested, a good cam producer or Pontiac engine builder can help with this one. Other members, as well as other blogs, can give you advice or recommendations that have worked for them. I think cams with 112-114 LSA in the 270-290 degree duration and up around .500 gross inch lift for a solid is about right in choice. But a smaller cam might actually work best all around -and the big cubes will offset the need for a radical cam and still smoke tires. Hydraulics will be a little different choice as well as a roller cam.
I am building a .060 455CI and kinda am leaning towards the Crower #60310 solid using 1.65 rockers. The lift is a little higher with the 1.65 rockers than I would like, but the .022 and .024 lash knocks this down. I could use the 1.5 rockers which the Crower cam spec provides and drop it down to some good numbers as well. SO, when I have figured out my true compression ratio, I will then call Crower or email them, give them all the details and see what they say as to if I can use this or not for my application. Should be a real stump puller by my estimates in the build I am doing. May not work at all on someone else's ride -heck, might not be what I need either.
