well it depends on how you set up.  higher lift cams tend to not kick into power band as low.  i rely on my gears to get mine going then when the rpms come up i have all the power i need,  were the mopar springs doubles?  never saw the mopar kit
YJmech, you mentioned you dynoed your engine and got around 200HP - what rpm was that at?

Bigger injectors don't GIVE you more HP, they only provide the motor combo with the fuel quantity it needs.  If you go with too big of a cam, your stock injectors may/can get maxed out and the motor can run lean under WOT.

i'm not sure to which post you replied but your statement in itself is conflicting - if you run lean at wot due to the fact that your engine has the capability to ingest more air (by improving the VE) by giving it more fuel you are actually making more power (and i am not talking when you run too rich).

I'm running the Hesco unit and I like it its the RVOB04 ive posted about it elsewhere but eh mopar computer will hand a fair amount of cam. I also played with high ratio rockers but eh cam is too much for them.

If your engine does have the capability to take in more fuel, the fuel injectors will provide for that; conversely, simply putting bigger injectors on a stock motor will do nothing for you compared to a header or a CAI.  :)

hint: read the title of the thread and all the posts in it, you must be thinking of another thread.
