Work yes, but most likely would not be optimal. I'd look into a PD cam if you want to go in that direction in the future.

So what else that's not included is needed to install this kit and have a true 100,000 mile setup?

Aftermarket DOD/AFM delete kit?
Katech valley cover?
Comp Cams phase limiter?
Comp Cams trunion upgrade kit?
C5R timing chain?
oil pump?

I'm sure some gaskets and what not, kit just seems a little imcomplete.

mine did not come with a cam phaser limiter or an aftermarket delete kit but a tap and plugs. and there were no different timing chain or oil pump because mine only had 800 miles on it. and yes there were a lot of gaskets and shop supplys.

Will I be able to keep e85 if I go this route? Currently FBO 450rwhp. Looking into cam/heads and want to go with the gm set up, but I'm not sure if ill need a fuel lobe increase that would prevent me.

If I'm at e85 fueling limits with the cam, can I do injector and zl1 fuel pump, or does the bigger fuel lobe still need to be present?

Did you end up using the stock converter for this or did you have to swap out? Also, either way, how is the street driving characteristics of the cam?

I don't see why you'd be out of fuel with those mods on E85. Yes, if you cam it, I'd go for at least +32 fuel lobe.

You can go higher than 5ms. Try to stay under 6ms. Pulsewidth will vary depending on where your tuner runs your A/F at. You should not run out of fuel with a FBO setup
