This thread is great. FTW fuel is awesome just a little pricey for me. I am on E85 now. Most of the numbers above are claimed on FTW so how much can I subtract for E85 numbers?

Ftw adds around 10-20rwhp on top of e85 i believe.

The main differences between the posted numbers on these cams is lift and duration. Cobra jet cams run a much smaller intake duration and a slightly smaller exhaust duration. The centerlines are almost identical. Lift is of course higher on the CJ cams as pointed out in this thread. The unknown is ramp rate and I believe from posters on this board the stage 3 ramp more quickly. Makes sense when you hear the ford engineers say the CJ cams passed their full durability cycle of a regular street car requirement.
I went w boss springs because I'm staying under 7500 and I don't race much except quarter mile here and there. Don't need the extra force and contact stresses on pivots and such.
I would guess boss has more focus on the exhaust breathing for some reason, but I have no idea. My contacts told me "don't believe the fan boys" about the comps vs. their cj cams but I'm also taking that w a grain of salt too. These engines also have a hard limit below 14mm of lift from what I was told by inov8 who work on a v8 supercar coyote development thing.
Short answer I think the CJ has better power band but less peak.

The main problem i've seen with making NA power on this platform is not the coyote itself, but the transmission having a hard time keeping up... You need RPMS to make high NA power, and shifting over 7500 repeatedly seems to take its toll on the trans. Would love to have a 500+ whp coyote, but "at what cost" is always the kicker... Granted 475-480 with a 100 shot wouldnt be a bad gig either haha.
what you said is exactly what everyone knows already, im going to drive the shit out of my trans until it breaks and ill just fix it then.
