"cam only" horsepower record?
at people mentioning 400 RWHP with the CC306 and GM847 with no head work!

I dont think driveability is going to get any worse if i stay with the same cam. the car makes plenty of torque as it is. I can putt around at 1800 rpms all day. The car does have a rather narrow power band as it doesnt really wake up until 3500 rpm or so but when im racing i rarely see under 5k anyways. I am just going to leave the 306 in it, put a fuel system in it, finish bolt ons, and dyno tune it and i will hit 400 whp.

hmm. are you saying your gonna go with a custom grind cam with stock heads???? then keep the same cam im having trouble understanding this......because once your heads flow more youll be able to run a bigger cam just get heads and cam whats so hard about that.

I dont see a point in running a large lift cam with stock heads, because the stockers dont gain much over .525 lift. Pm Gizmo, he is a living encyclopedia of information.

The hp isn't the problem, its the stock heads not being able to allow enough air to pass through the valves at the rpm that the cams good for. You want a 400whp cam only setup, swap to a LS engine.

Not tryin to rain on your parade...but you seem awfully confident that you'll be able to hit 400rwhp cam-only with a cc306. Don't you think if it were easily done with off the shelf parts, it would be the hot set-up?
If it were that easy, you would have heard of a whole lot of 400rwhp cam-only LT1s by now. I mean LT1 guys have been running the old cc306 since the mid 90s...I would think someone would have figured out this formula well before late 2009.
Best of luck meeting your goals
Honestly though, if you are dead set on your cam-only 400rwhp goal, I see a solid-roller valvetrain in your future...

I think that it may be achievable; i just think that most guys would rather throw some heads on it becuase that is easier and conventional. i appreciate the luck and we will see what happens.

guys i know this seems far out but hey, what if? If i can not hit 400 rwhp nothing will be hurt only more power gained from what i have now. lets just hold on and see what happens. All of this work will be executed in the next couple of months so we will all see the results soon.
P.S. I am not saying that stock castings suck for porting. Lets not turn this thread into a debate. I simply am just not going to go that route when i do get heads.

what do you plan on doing differently from what guys have been doing for the past 15 years?
i think your main concern should be finding the "right" dyno with with an operator who knows how to help you acheive your goal.
after that, you should post up some timeslips.

I will be doing whatever it takes to try to reach this goal. If it soon becomes obvious that its not going to happen, so be it and i will quit.
What i will be doing is: 30 or 36 lb. injectors, racetronix fuel pump and harness kit, finish bolt ons (throttle body, ewp, roller timing chain, etc.), cut outs, and a dyno tune.
If that will not put me there i will stop.
My car is making pretty good power now: http://www.youtube.com/watch?v=vT5L6JxR7K8

The only problem Is Im doing this with some of the best ported stockers you can get.
The heads will limit the cam not the other way around. You could put a top fuel dragster cam in your car and the heads will limit the power it makes. I think you may get close but 400rwhp will be really really hard to do. I would suggest calling Lloyd Elliott and speak with him about your goals!
