Stock LT5's should be peaking around 5900 rpm...maybe a couple of hundred rpm higher for the 405hp cars.

I would not get too carried away with wondering how the cams are timed etc until you check the fundamentals. You should be able to pull to 6000, especially with headers. Is your intake boot collapsing?

Looks like you have plenty of fuel up high..like too much, I would have expected 12.5 AFR from the factory VE table.

ON Edit: extrapolating that curve should put you at at least 350+ whp
