Default f11 or f13 for me

f11 or f13 with 3k stall and 3.73 gear, i can always upgrade the stall later to a 3500 or more, but i cant beat futral motorsports gp they got going on..

im pretty sure i could get buy with the 3k stall, since i have teh 3.73's with the f13, but perhaps going a bit smaller with the f11 would be the right choice, i dont think they'd make 5hp or 5tq difference throughout the band tho do you?

Either way they are amazing cams. I have the F13, but its in an M6, so i can't comment on your situation.

Driveablility is awsome and i can't complain. If you had LTs you would gain more Hp an Tq, but your macs will do just fine. Check out the Dyno section, there are a few of us that get into detail about every characteristic of this cam and i can promise you either way you will be smiling!

great.. i will prolly just do the f13 then unless someone chimes in its to big. i know id get more hp and tq from lt's.. prolly 5-8rrwhp.. could be the diffference b/t 392 and 400 ya know.. but im not getting greeding.. i just would like to crack the 11's n/a and see 370 since i have ls6 intake... that and decent tq down low, i can always up the stall speed later as i can swap out to lt's.. i figure for the price of the cam i could add lontubes, but which is gonna make more power, lt's on stock motor, or cam, hehe, plus i got non rusted macs for 250 total with ory pipe, cant really beat that.

He is correct. Elijah had great results with the F13, I had great results with the F11, you can't go wrong. If you want an idea of the F11's idle (and they really both idle almost identically), here's my vid. As far as the power difference, Allan said there is a 5-8 peak rwhp difference between the cams in a cam only car.

so ya'll dont think i would be able to tell a difference b/t the two cams by "seat of pants"... i mean drivability wise i prolly wont be able to tell since there so close, so its prolly best to get the extra 5-8rwhp i wont be able to feel either lol

I have the 11 and kinda wish I went with the 13. Read the 13 is worth a few more ponies with very similar idle qualities. Like someone said above can't go wrong with either.
