Get a custom set of cams, wich will allow better flow in the upper rpms, and alot of head work; then you may be able to use rpms over 6000 to your advantage. Until the day that these parts are added to your motor, you're stuck with the 5500rpm or less power curves of our motors. That's why it just doesn't make sense to ever need to hit the rev limiter of our motors.

I suspect that without port work, dusty's bored out motor is going to be even more RPM limited...
Brent has had oversized valves made. So they are there, but not necessarily cheap. If you are going turbo, the exhaust valve needs to be upgraded much more so than the intake valve... In my opinion, if you had cash to do either intake or exhaust, but not both, I would recommend exhaust. Maybe a +2 or +3mm...

My stock head/cam motor was making all hits power above 5000 rpms. I think if you have a huge turbo it makes a big difference on the top end, regardless of the crappyness of the heads. This is why Im hoping that big cams, decent heads, and a big turbo will compliment each other for the higher RPM's. (also the short runner intake manifold)
I would love 270-300whp from 5psi boost but I might be smoking crack on that one because I dropped compression considerably.
Also there is no way I can do 270-300whp on a 6000 rpm limiter. Frank and I figured my peak power was comming around 5700 rpms to get about 245whp on 5 psi boost. Gaining 30whp on only 5 psi boost with cams and headwork is probably not close to possible unless I have peak power at 6500+ rpms on an aftermarket computer.

I agree w/ Brent regarding the top end. I did notice a considerable difference w/ my worked heads in the upper RPMS. It seems to pull better there now. It's far from stock, but far from seriously modded.

In my opinion Turbo is definatly the way to go if you run it on the street. if it is a track only car either would be a consideration but just the potential of the turbo as well as being able to cruise on the freeway under no boost (saving lots of $$ on fuel) really encourges the turbo. I've got about 40K miles on my turbo 3.0 and it still gets over 30 mpg on the freeway and around 25 mpg around town.

Most of us have all the pictures on our HD's already :P
There are some on robskorner.org
Probably most of them are on the 3.0 list though.

Not to mention the strangely stained hardcopies hidden away in odd places, eh?

Is that for real? Dodge actually built those? And theres real cars that are driveable with them? that is so cool, and one pic, its actually mated to a 4spd?  That is too bad they didn't build them, that would have been one sweet ride in whatever car/van they put those in,
