If anyone has any recommendations on wheels and tires that they know will fit, send em my way I looking for the lightest and widest. I've heard 305s will fit but if I can get 325s with no mods I'd rather have them.
Once I get tires on her, I'll be ready for the track and we can post time slips that reflect the dyno numbers.

Setups like this impress me more than my own stroker that's making 630 at the flywheel.
That cam is small and super driveable, and nothing on this buiild list is crazy expensive including the heads. AI does great work, and clearly Spartan know their s**t with valve events. The torque is stupendous. I have seen 450-460wtq and been impressed on cam-only setups. The extra compression and short intake duration is definitely helping this engine.
You don't even need the Fast 102. I have seen 15-19whp and healthy torque increases from a proper port-match of the LS3 intake mani, which is one of the best OE manifolds GM has produced to date.
Cliff's notes: if my 402 ever dies, I am swapping in an LS3 with these specs! Thanks for posting your results and doing a bad-*** job without overcamming stuff. :-)

Don't you have some more ticking time bombs to go sell? 
Vids will be up shortly after the FAST pulls, which will be Thursday morning.
Unfortunately due to my busy schedule we don't have a lot of time to do that much R&D. We're moving straight to a FAST 102 system with FAST fuel rails. Back to back results will be up Thursday afternoon.
