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!

that torque isn't "off idle." the chart is in run time rather than RPM....0 seconds represents 2800 RPMs....still nice numbers but you should try and get a print out with RPMs at the bottom.

Looks like his RPMS are on the right side of the graph. Looks like 446 TQ is coming in at around 6200 rpms.

I like the power curve. I don't mean to be that "guy," but aren't hp and tq numbers supposed to cross around the 5250 rpm range? It looks like it crosses at the 6300 range. Maybe I'm reading it wrong.

It's just the way the graph is set up, would be better to have the rpms at the bottom. Top of the graph does say horsepower and torque vs time. Maybe the rpms on the right side of the graph are moot.

Actually, look at the green line (rpms) and follow where HP and Torque cross, it's right at 5250.
