Default Doing cam only? TR224 or VRX3 on stock heads

I'm thinking that cam only might get me to my goal of HP on my street car. As close to 400 before heads as possable. Car will be pro tuned after install

Full bolt ons A4 99 corvette 342 rear

I been going back and forth between the 2 for a week now i just cant pull the trigger

With an auto, you prob wont get it, even with all supporting bolt ons, tune, and even a U/D pulley.

The VRX3 has hit 403 on a m6 car with stock rear. Check the dyno meter section.

That VRX3 "cam only" car that hit 400hp ...not so sure.

I have the VRX3 and my car only musters 363whp with headers. Installed and tuned by Vengeance themselves...

Personally, I am big on the G5X3 Cam, but that doesn't really help you. Good luck!

Stock 346 LS1 doesnt "need" supporting mods, but they dont hurt. Quit complaining about your miss-matched combo.

I've seen CC306 CAM ONLY LT1's running slower then stock at the track, just becuase the car gets a cam, doesnt mean it supposed to make the best power.

I'm not sure how my car is any more "mis-matched" than the car with the same mods that put down 400 at the wheels with the same setup...

What is mis matched? Can you elaborate more so I can understand what is wrong with my configuration?

Not all LS1's are created equal, when you work with enough of them you will know then. When Vengence tunes your car with their cam and says you need to put supporting mods on it, then you do it.

This is a Fbody vs a GTO, the air intakes are different, maybe its that, or the IRS is eating up some hp.

Your complaining about a "dip" which may or maynot be tuning related but your off 40 hp from this dyno graph. at the peak hp.

If you think its tuning, take it somewhere else, see if they can improve on it.

EDIT:

Oh and Ron did respond to your post.....

No doubt the IRS and intake are different. I will try to get the full bolt ons and see what happens.
