I'm not a turbo nor S/C guy. But if you go to places like BTR, Cam Motion, and Lil John you can compare listed cams.

ok. good to know

Wants to run pump E85 but I cautioned against that. You may get E70. I would like to see him set it up for pump 93
Pump "ethanol" E85 will require a lot richer mixture but will also tolerate a lot more compression than pump "gasoline" 93.

What's the control system? Is this with a fully electronic programmable FI and ignition? Flex fuel sensor?
Programmable FI but no flex fuel sensors

.617/.595 lift

close enough Craig?

static compression come to 10.5:1. I think he will have to be conservative with the boost 10psi. Am I wrong?
Yes something in that vicinity is fine. Less comp if possible , 9:1 will make it less picky on fuel and tolerant of more boost, it will still drive nice off boost too.
But, what turbo/s if he using?
Ordered pistons to get us down to 9.5:1

Cool, that comp and cam will make a nice potent streeter
