Its a smaller cam, that will have great driveability. You have the heads to flow for a bigger cam, so if you dont mind some mild cam surge and hard loping, I'd go bigger. CC306, or preferably, a GM847. Or Custom grind cause you can squeek some more power out without losses in driveability.

Well a 306 is giong to rev every bit as high as a GM 847, but its an older outdated lobe design. A 847 will have slightly better driveability, and the same or slightly more power than a CC306.
He's gonna have the heads, so get a cam with extra lift, even if it is shorter on duration. Since they came out with a CC503, im suprised anyone is even still buying the CC305 cause its same RPM range, similar idle quality, and a little better TQ/HP across the board.
If you dont wanna rev it that high, at least get a custom grind cam to take advantage of the heads. You can run a tigher duration, higher lift set up on a tight LSA that way it will have a narrower powerband and wont need to rev as high but can take advantage of the high flow at higher lift with the heads.

Bret was pretty fast with mine. I ordered it off of him on a friday, and recieved it like 2 weeks later.
If you dont want to rev it high, He'll probably grind you something similar to a LE1 or LE1.5. Thats what I have. Likes to be shifted at 6200-6300ish on stock heads. But definatly pulls harder across the board than the stock cam, from say 2000 RPM's up.
Really decent driveabilty also. Read the thread I have going on now about it since i have it all together. Id reccomend Bret to anyone. And as a heads up, its fastest dealing with him through PM's on here. His name is SStrokeRACE

See, you did exactly what I am saying. As long as the lobe profile isn't too radical, you will always gain power from the extra lift, with no driveability issues.
Longer duration is what makes cams choppy, surge, etc.
I think since you have the heads, you should get a custom grind similar to what Stl94LT1 has.
PM Bret and let him grind ya one. He doesnt give out the specs, but myself, and many others, can vouch that their satisfied with his work. Lloyd Elliot has him spec the cams for their packages for a reason.
Since Joe Overton quit doing custom grinds, im not sure who else is out there for LT1s besides Bret, that I would trust, and is easy to get ahold of / deal with. FWIW, Bret also helped me with any of my stupid questions I ever had for him.

Thats probably a little more duration than your going to be happy with. It will lope hard, and probably have a little cam surge driving.
Granted, a dyno-tune can eliminate alot of this, but it will still be there.
Id say your fine on the lift though, as long as you have springs that can handle it. You wont loose driveability from too much lift.

I have the 305 and i made 310 hp with no tune on a mustang dyno. She was still climbing but i didnt want to spin her over 6k. With just headers and a cai i went 13.2 at 106 on street tires also not tuned yet. Hope this info helps.
