Default F11 to F12 or F13?

Would i see any significant gains going from an f11 to an f12 or f13? Car is a 98 TA auto w/ all the bolt-ons, vig 3200, stock rear but adding 3.73s - basically im putting everything in it that i had in my z28 before i totalled it and just wanted some opinions on the cam before i get it put in. z28 Made 388rwhp w/ those mods and f11 cam. thanks guys.

From what I've seen when I was researching cams for months (before I decided to go the blower route) the f11 only has a few HP less than the F13 and a bit less under the curve. However, if it isn't on the car yet maybe you could sell it and then get the F13. After all it isn't like you have to take it out and throw a new one in which should cut down on some of the costs. BTW, the F13 was my cam of choice too, followed by the G5X2.

If i stick with the f11 i will have to pull it out of the old motor. Well not really but that motor has 108k miles while the motor in the ta i just got only has 77k on it, maybe i will be better off by just buying a new cam/valvetrain and just selling the old motor. i dunno, anyone know much bout the f14 cam?

Allan told me there is only about a 6-8 rwhp increase from the F11 to the F13.

What RPMs would you be shifting at in the F11-F13?

Might want to look at the F14.. It just made some very impressive #'s in the dyno section that are almost too good to believe.

Peace,
Josh
