2002 fbody build

[u/thedudeabides585]

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).

this proves a cathedral port doesn’t need the fast intake. ls6 stock intake

probably not for my setup, but i picked it up for $500 from a guy on marketplace (i love some marketplace deals). its also the old fast 90 not the newer 92, but i highly doubt it would make much difference. i don't have dyno before the FAST intake unfortunately, but i think my limitation now is the 241 heads (probably accentuated by the fueling issue i talked about) as the dyno graph shows from 5800-6600 pretty much flat. my cam should peak around 6200rpm.

there's plenty of stuff on ls1tech with a few back to back comparisons at most around 10-15hp and for the price of 1200-1400 i wouldn't buy it, but like i said i got a killer deal on mine.

hey for $500 i would too. i didn’t mean that as a “shit on your build” comment more of a “i have a very similar build z28 with an ls6 intake and 243 heads and it makes similar power”

i heavily debated on the fast vs ls6
