f-cam from stock?

tossing around the idea of an f-cam as I still run a stock one.
What idle rpm are you guys running with the F-cam with out the car shaking?
what kind of rpm range are you guys running in an f-cammed street car?
currently I'm not going over 5500 to keep the stock block intact.

At around 900 RPM the car has a slight rumble to it...perhaps a tad more than stock. 850 RPM was quite a bit more pronounce...but still docile. Under 800 and you could really feel the shake...and it sounds great to boot!

Your car would be a good before and after test for the F cam. Well documented before the swap-numbers would be meaningful.

rpms kill way more than power.

My idle was set at about 850. I liked it, fairly smoothe. Shifted at 6500 to 7000. Yes stock block, yes 142 mph, crossed the traps at around 6300 to 6500.

how long have you been running those numbers and keeping the rpms down?

I run a dual stage boost controller that activates the Meth at the higher boost level. so in everyday driving I only have like 425-450rwhp but if I flip the switch I get the bigger #'s.
2 summers now, aprox 7-10K miles.
I do find myself flipping the switch alot more now though.
This summer I think I'm going to try some chip tunning in hopes of leaning it out a little below 4700rpm as currently it's super rich. I don't know if the hp # will go up but I'm hoping for 700rwtq.
