LT4HotCam to CC306 worth it?
Will all this work be worth it? Car is set-up well now. LT4 Hotcam kit with ported heads, fuel system upgraded, headders, exhaust. Car made 350rwhp as it stands now. Upgrading to CC306 cam, 7/16 studs, large valves, comp r lifters. Hopeing to break 400rwhp.

Need to know what your heads flowed.
Also about the larger valves, I gained a little flow on the heads by going from the stock valves to the larger Manley RaceFlo valves. The opposite happened on the exhaust side- the stock exhaust valve flowed better than the Manley RaceFlo valve. I think the larger Manley exhaust valve shrouded a little more in the chamber which is why it didn't flow as well as the stock one.

Don't have flow numbers yet. CNC heads is doing the work. I guess what everybody else gets from his work would be a good guess. Car pulled 108 traps so it does run strong now

I know its not much to compare to, but my setup ran 109mph on a horribly slipping clutch. I am on stock heads. That was the only pass I made, and hope to make some more soon.
My friend that I got the cam from was trapping 114 with lt1 castings ported to about their max. He dynoed 396/375 through his 10 bolt, and lost a few when he went to the 12 bolt.
Expect stocish power below 3k. Nice pull up to @ 5500. 5500-6500 its a monster. Are you on a stock bottom end? How high are you prepared to spin it. The buddy mentioned above just spun a bearing spinning his 847 to 6800.

No, bottom end is not stock. Balanced and Blueprinted 353 (bored .020) forged pistons, well stock crank and rods. Pulls to 6200-6400 no problem but I know this cam wants more so that is why I am going to 7/16 studs, guideplates, 1.6 NSA rockers, double springs, titanium retainers, 10 deg locks. Trying to make the top end strong.
