is anyone running comp cams with the stock head? roughly is 280's too big for the stock engine management/head? or is 272's a better choice? please pm me with answer if u can

There's good power to be extracted out of the stock head no doubt, but this certainly is relevant information. Kind of puts a new perspective on cars that are mostly stock running monster "big duration number" cams. Thanks.

I think he means installing them like mine, with the stock cam gears.
I'd really like some shop input/dyno on this as far as what's left on the table without adjustable cam gears.

I think a step up from these would be jun 264's with springs... reason being is they should have the same top end power, while having more under the peak, better all around torque, and better idle.
That actually was my first choice. However, I decided in order to do everything I wanted to the car, I needed to comprimise.
I figure I'll just make up for it later on by bolting on a 50 trim kit lol

One member here retarded the Comp Cams 280 intake to -4 as per my recommendation, and picked up ~20whp. A 400whp car should probably pick up around ~15whp with the same adjustment.
As for the lift (~11.0mm/10.4mm), it's ok. I just wanted to point out that a suitably ported head will be needed to take advantage of that.
Finally, if this cam set is ok for use with the stock valvetrain, this indicates the ramps are probably too mild for what I'd consider for a race application.
Just my thoughts, FWIW.

There's nothing wrong with the Comp Cams 280s, but the 104/112 LCs are relatively advanced, and favor midrange torque as opposed to best power. Installing them straight up would be similar to installing a set of HKS cams at +3/+1.

According to comp cams, the upgraded springs are recommended for high boost applications?!
Are they afraid 35 psi will keep the valve from closing?20 whp seems like alot for the price of cam gears, wonder how it would do on mine

As for what cam gears and different settings would do, that depends on the application. If I were using these cams and wanted best possible drag racing settings, I wouldn't hesitate in investing in a set of cam gears and doing something with that 104 deg Intake LC.

I would be more concerned that using the factory springs would cause valvetrain deflection and fatigue, neither of which do anything for power and longevity.

Currently on my ~500 AWHP 50 trim set up my gears are set at +2 Int, 0 exhaust.
