A month ago i picked up a set of used stock heads with Comp Stage II blower cams, comp springs and retainers, and livernois phaser limiters. They were installed over the last week at Ramsey's Performance in Lutz, FL and tuned up today. First impressions: HOLY FUCKING SHIT. After 5 pulls, it went from 420hp to 509hp (at 6300rpm)!!!! a/f is around 11.7 throughout and considering that before the cams, it made 420hp at 6500rpm, this is a huge improvement.
Boost was at 9.5psi at 6300rpm, previously it would be around 11psi with stock cams. Sure we coud have revved it out some more but none of was thought it would a good idea. We pretty much knew there was still a lot more power up higher in the rpm range :)
Also this is through a PI converter, alum. driveshaft, and 4.10 gears.

I'll post the graph and a video later. The idle is sick i f'ing love it. Big thanks to the crew at Ramsey's Performance!!!!!

The shortblock is stock with 51,500 miles (!), dyno sheet will be up shortly although it may be difficult to read.

where can you feel the gains the most

Hard to say because any kind of aggressive throttle past 3000rpms or so starts to spin the tires. but man, coming out of the roundabout near the gate at the air base i would always pop it in third and then nail it, the car would steadily go faster. I did it today with the cams and as soon as i stepped on it, the tires broke loose. in third. it seriously got faster everywhere
