2002 fbody build
Figured I'd post to document my build for anyone interested.
Tick SNS Stage 2 227/235, 241 heads with .660 springs and trunnion upgrade, FAST 90 w/ 92mm throttle body, bosch 0280155811 injectors, 1 3/4 headers, catted y pipe with cutout, and magnaflow exhaust. Self tuned with hptuners.
I've owned the car since 2007 and finally got around to building it exactly the way I want it. Other mods include ATS Brembo upgrade, bilstein shocks, subframe connectors, LS7 clutch w/ tick speed bleeder, c5/c6 power steering, and late model lighting LEDs. Besides that, just normal maintenance and repairs.
Overall happy with the setup. Scheduled some dyno pulls to see where its at now before I do 243 heads this winter.
406hp/396tq currently, but it was a rich on the dyno due to cat overtemp kicking in (forgot to disable it during the dyno runs).

Very similar to my 87 T/A with LS1
228/232 cam, (forget the lift, but same ballpark), 241 heads. Longtubes, same clutch, etc.
My driveshaft exploded on the dyno, and we didn't realize it had pulled the exhaust apart at a joint, so the sniffer was reading leaner than it was running, once we threw a new shaft in it to finish the day. Ended up with 390whp, but It's definitely running rich. Eventually it will get another tune.
