If you're going cam only and not changing the heads as well, I would recommend either a Comp Cams CC503 or a Lingenfelter 211/219. The 503 is about the most agressive cam you would ever want for stock heads and makes great power, while the 211/219 is a much more mild cam that gives a nice low end grunt. Personally I favor the 503.
no horsepower numbers but i did drop a full 1 second in the 1/4 mile. went from 14.0@99 with just LT headers to 13.0@106 with the hotcam(stock trans both runs). i think it still has at least .5 seconds in it once i get my performabuilt level 2 w/ a 3,000 stall next week.

because i think a higher average would be more benificial then a higher peak...
i opted to go for the 227 cam cuz it has a great curve...

The complete LT4 package with aftermarket injection did put out 425hp flywheel for a magazine.
If you make good choices instead of that bad one you can have that kind of power at the wheels instead of at the flywheel.

I just installed a LS1 Hot Cam in my ride and my friend installed the LT4 Hot cam in his and both of ran 13.7... Of course he has LT's, Ory, K&N Kit,3:73 and a cut out on his LT1 and I ony have a Lid on my LS1... On the Street I took him top end... After the install he took me first Gear, I pulled in front second, third he pulled crazy style and was in front by maybe half a car, but fourth If we would of kept going I would of took him because my car was creeping quick. It made a good difference if you ask me and his car sounds freakin good.
