I wouldn't change a thing except octane and oiling system to rpm another 1000+. Fantastic numbers, low to mid 700s at the tire on 91 octane at only 6000rpm! Should touch near 1000hp if it like timing and keeps pulling upstairs!
That's Josh at JMB, he is really good at all that stuff (website, videos, logos, etc.). Now we are working on getting better quality video itself (stabilizing, multi angles, etc.) This is a start, but I think we can do much better with more experience.
Thanks!
With a ported intake (with Gen3 TB), valve covers, fuel rails, headers, tune, camshaft, gaskets, install, etc. You are around $13k. Should make an easy 600+ WHP, likely 625+ on 93 octane, depending on camshaft selection.

James' came in for a simple but very effective mods list:
M+M Headers
JMB 3" catless exhaust
BBK TB
JMB NA63X Cam and Valvetrain package
K+N air intake
SCT Tune by JMB/Torrie
3.55 gears
Made 544whp and 553WTQ SAE (560/570 uncorrected!), with gains everywhere, no loss of torque down...
