Can you get to 400 without turbo or super-charger

Anyways i also am a member on my350 and guys with VQDE's and Revups all manage somewhere around 250-270whp on average with full bolt ons and their respective tunes. I have seen guys with 270-290 range with cams and head work and the only 300whp + NA ive seen is Adam's from Z1 but he has a fully built 3.5. Now the HR has been showing that it responds better to bolt ons because guys with 07-08 Z's are getting 300whp with a I/E setup. There is a guy with an auto 07 making 320whp with full bolt ons and TS reflash. Now the 3.7 also seems to respond well to bolt ons and im gonna go ahead and guestimate around 300-315whp with I/H/E setups and 320-330 with I/H/E/TP/pullies/tune setups. Now to go higher than that we are gonna need cams but someone needs to crack the VVEL on the intake side first. This is all speculation tho. We are just gonna have to wait and see until more parts come out and more people mod their cars. But i cant wait for that and cant wait to see what GTM, Technosqare, Top Secret, Amuse, and all the other compaines come up with. I hope that the 3.7 gets the same aftermarket support like the VQ35 did but seeing how compaines are going bankrupt and the value of the american dollar dropping, parts are gonna be harder to come by and more expensive...
