Here is a post on my LT1 from the summer.
I went to the dyno today .. The car has an untouched from the factory stock bottom end.. I have Lingenfelter ported heads and Joe Overton did a custom grind cam. Eric Bradley ported the intake, throttle body. This setup has been in my car for almost 4years . I converted the car from an auto to a 6-speed and added a strange 12 bolt... The car dynoed N/A 416.4rwhp and 398.7rwtq after it was tuned a little.. Then i made one run with the spray and made 608.9rwhp and 657.4rwtq.. I am very happy with this setup .. This is a full weight convertible with a/c and everything that came on it from the factory.
The tune was on the mild side because the bottom end is stock 12.8 a/f. n/a. I sprayed 175 shot.

Car's been running for 3 whole days with the new setup so not yet but soon. 
And you're one to be talking trapping a whoping 114 mph with a heads/cam LT1 
And I did dyno 405rwhp with my old setup... I also trapped 118mph out of heads that flowed a whoping 240cfm.
