Rich, I bought my cam from a forum member NOS and it was shipped without the cam card. When I measured the cam, I got .320 for intake lift and .318 for exhaust lift. I am using CadCo stage 1 rocker shaft @ 1.60 ratio. Still plenty of power for me and fun as all get out. The motor idles at 900 with a smooth tone. Last night I dropped the idle down to 700 rpm, I can hear more of a lope but nothing like what your going to hear. I believe the old MTS saying that power brakes will work with their 15, due to the LS and CL. Back in the day they wanted to cut a stronger cam that didn't sound to far off from stock. I believe your cam has the jump on mine in all areas. Sound power curve, FUN FACTOR!
Remember, Its your build. Advise is great and needed. In the end your driving the car. I built mine on a very very cheap budget. I spent close to $2,200.00 that's it. The machine shop is were I found Cost me the most. Between the heads being shaved and the valve bosses being milled and brass guilds. I knew then I couldn't afford to have the entire block decked etc. I used NOS- fuel pump, Holley red, cam, lifters,and second hand rocker shaft w/pushrods, new gasket rebuild kit. New Springs etc., used Ebay Holley 780.
The $2.2k even includes a rear truck axle I bought not knowing that a 12 bolt truck axle is weaker than my 8.5. All of this was over time. Just look back at post 81 Trans Am.
I followed "WildMans" advice, I.e. Cadman, AKA Mad Banana, AKA better looking of the two ugly twins( Thanks D

He said, PJ make a plan and it takes what ever $$ it takes.
So I then realized I wanted a bad ass ride but didn't know how to do that. At All . I got sucked up into all the hype of the build that I wasn't thinking about the total car and how each part works best together.
So working with I had, A stock rebuilt motor,(100.00 mechanics auction

)
made a list, I wanted it to last. Like forever, and settled for fun factor because really I can afford that and not the bas ass I wanted. So Im still plugging along that list every year acquiring parts that will compliment each other as a total package.
I LOVE MY CAR!!! Its not a show queen, IT FUN and I built it!!!
You have a great cam,IMO, You will enjoy it so much. As long as everything else works as a total package.
BTW, Lowering my idle, oil psi went to 25, but it doesn't creep in drive and will smoke the rubber at a blip. Go figure

That's with the Old grind.
Your going to LOVE that cam bro.

Try removing the "splash guard?" thingy from inside your valve covers. I used a Dremel. take your time around the spot welds that hold it all together. The metal is thinner there.
