Default 408 put down 475/475

Just had my 408 tuned over the weekend. 6.0 iron block, PRC Ported/polished LS3 heads, 235/242 .635/.615 112+2 LSA, LS3 Intake and she put down 475/475 with 100% humidity. hoping on a nicer day and removing my crappy ChokeMaster exhaust with an LM1 i'll get closer/break the 500HP mark!

I also had 444TQ coming off of idle which i was really impressed with!

Jimbo- I couldnt be happier with my motor! It was a lot of money and a **** ton of work building/swapping my motor but in the end when i saw it on the dyno, it made it all worth it

I'm not trying to be a dick but 475rwhp doesn't sound right for the build. The torque sounds good though but I'd have expected it to make more hp

I agree. The torque numbers are awesome, but with those torque numbers, I'd expect it to be in the 490/500 hp range. I would love to see a graph.
