Not sure about totally stock or not. I know in the video from texas-speed, the engine dyno that they were on was hooked up to LT's. Whether or not they used the LT's to dyno with the stock cam or not, I don't know.

yeah i looked closer at the video and supporting mods=fast intake. haha. yeah dont have 700 bucks for that thing. plus that would be at the fly with no accessories.
my goal is 400hp to the wheels with minor mods, like cam lt headers and ls6 intake. no head work, just upgrade the vavletrain. possible? so far i have ported tb, long tube headers, ls6, and thats about it.

My ms3 gained 70 rwhp with long tubes, true duals, ported tb, pulley and tune. I do have the ls6 intake since I have an 01. The car put down 413 rwhp 380 tq through a 12 bolt moser and 4.10 gears.

The FAST Intake wasn't used for cam-only pulls, it only added later on that day after we did a head swap and a few other cam swaps, so thats the wrong video for "cam-only" (That particular dyno video was 551hp at the flywheel with the MS4, PRC LS6 stage 1 heads and the out of the box FAST intake!). The before/after engine dyno testing for the MS4 was using stock 853 casting heads and a LS6 intake with stock unported TB/MAF. The headers used are purpose-built dyno headers from Kooks for engine dyno testing.
We'll be doing more engine dyno stuff in the future.
