im swapping cams already and my previous set up i was running a comp 266hr-14 wich is 210 220 duration 500 510 lift 114 lsa on the dyno i made 277rwhp and 339tq. im looking to get at the 300+rwhp mark and im thinking about running a cc306 or cc503. im just looking for some input from you guys who are running them or have before like how it idled, and what power ui guys made

i might just go custom grind

honestly the cc503 will get you to your goals and be easiest to source and be cheap but a custom grind for some reason just brings more pride to the build imo

Was the car tuned ? Those are stock numbers. you should be atleast 340 rwhp with the ported heads and that cam. Something is wrong. Changing cams won't fix it.

Excellent Idea!

the guy who tuned my car said stock lt1 make around 230rwhp on his dyno. my head work wasnt the greatest and they werent flowed. the dyno sheet showed the car hp curving off at 4800 rpm and the cam i have is 1000-5000rpm. he showed me a dyno of a trans am cam only that put down 310rwhp so honestly i was expecting to be 320-340rwhp. he said if i put in a bigger cam ill be over 300.

Something is wrong - the heads are probably no better than stock. The cam is also a bit on the small side, and the dyno used resulted in relative information anyway.

A 503 will wake the car up, and without knowing a lot of information about the head flow, getting a custom will likely result in no better results that the 503. I'd assume the heads are stock for the purpose of selecting a grind at this point.

yea we narrowed it down the reason it wasnt making the power i wanted was because the heads where basically just "cleaned up" and the cam i have is small thats why he said if i do a bigger cam i should be over 300.

Just a reminder, I have the stock heads and cam and put down 309 rwhp. I would check into the head work. I do believe that cam should pull to 6k before dropping off. Alittle more info would also be helpful. You may have a dished piston or something.

Any cammed lt1 should be over 300. Bolt on cars should be too. 300 is weak.

What an ignorant statement - it presumes all dyno's are the same.

Something diff wrong for only 270 rwhp. I dynoed 270 thru a stalled a4 with botlons. Do u have any track numbers? Do u have 1.6rr and whats ur compression? Your car should make power beyond 4800 thats for sure. Im wantin to say my bolton motor peaked at like 5800.

Wat he said. Mayb valve float

lt1-xjs

We know they are not. Track times tell the story. A 300+ rwhp F-body should run 12.5x or better.

Sure.

Pick one in your statement for it to make sense;

Broken dyno
Broken dyno operator
Broken lt1
Broken lt1 owner brain.

You are such a piece of ****. I hope to we get the chance to meet someday.

An a4 car with LTs should bea near 285. The cam should get him to 300whp at least. There is something wrong. That's all I'm saying. You heroes need to calm down.

Pull the plugs if you haven't already
