2226 is a HXL lobe that is just a few degrees smaller than the lobe I used. Your 4134 exhaust lobe is a different family. That is an RT lobe with 266 duration.

If you replaced your cam with my cam I doubt you would see much difference. Maybe pick up a little power but I don't think it would be worth the hassle.

800 hp with the Trick Flow 270 heads will take some work. With E85 you can run more compression so you'll want to run as much as possible. If it is a race only deal you'll probably want to throw more cam at it than I'm using. Especially if you have more compression. Don't forget to get the intake ported, that is the key to unlocking some power.
