Low lift truck cam daily n/a 11 sec Z28
I did this back in October last year and I decided I wanted to get some feedback on my setup and officially join the club, So feel free to qritique it if you want, it's a super simple OEM reliable setup I can drive anywhere.
2002 Z28 all original onyx black with saddle tan leather chrome snowflake t-top 3 channel A4 3.23 car 107,xxx miles. I'm the 2nd owner, I purchased the car in 2004 from elco Chevy with 36k on it and it went 13.16@107 bone stock, the car then did 12.80's easily on regular H rated tires with free mods and the slp 2otl catback that I wish I had kept on the car.
Mod list today:
Cut bottom of airbox away
Throttle body coolant bypass
Whisper lid/ with fram air filter installed (I forget to pull out)
BTR stage III truck cam .5525 lift 218/224 duration @ 0.050 113+3 LSA
Blue GM LS6 springs that came with cam from BTR
Pacesetter 1-3/4 longtubes
TSP catted Y-pipe
3" intermediate pipe
Flowtech 3" cutout installed before the rear axle
Magnaflow 12267 muffler
Walker stock replacement tailpipes
Stock original black rectangle Z28 spouts
TCI 242932 SSF 10" (3500 2.5 str advertised) converter
Hays sfi heavy duty flexplate
Very mild mostly Original 4L60e lol
Stock aluminum d/s and u joints
Original 10 bolt housing with Summit girdle
GM 3.73 gears
Used LT1 style 3 series diff
Front Suspension is all original stock
Poly motor mounts
Rear has $20 Monroe shocks
Lakewood boxed lower control arms
Spohn non-adjustable tube panhard bar
Poly tourqe arm bushing on the stock arm
245/50/16 Nittos on a spare set of chrome flakes at 25psi
at least a half to three quarters full of gas in it too on these runs. Car weights 3500 with a 1/4 tank without me in it so I'd say around 3750-3800 race weight lol

I have a good friend who has hp tuners. The car was street tuned with a good wideband and then he just touched up the timing a bit on a local mustang dyno.
I'm going to see how far I can go on the stock wheels and stock size tires. I think I can push these nittos a bit quicker, plus I like that my car still looks completely stock. It's kinda my thing!

you can go on dragtimes.com and they have a DA adjustment calculator that you plug in the track location and date and then select the time that you ran and it'll give you what the DA is for that point in time.
edit-I agree on looking stock. I have a quiet factory catback with a cutout for when I want to get noticed lol.

I wish I still had the factory Z28 catback in one piece to go behind my cutout, it's pretty much impossible to get the tailpipes in perfectl alignment again once they are cut off the original muffler
Thanks for the info, I'll try and look at some of my earlier attempts and see what the weather was

I'll keep looking for one. In the meantime I bought a new cam to try with a little more intake duration and overlap to better take advantage of the converter and I want to try disconnecting the front sway bar as well. My car is black and still has it's Z28 badges on it no cosmetic mods at all

Thanks! Ill try to get some pictures of the car, it's still stock ride height and it has aged fairly gracefully. My setup is completely dd friendly and as reliable as a new suburban. (I forget to mention earlier the R/V sized transmission cooler I put on it) I really do get to have my cake and eat it too with this setup

I reinforced the stock exhaust outlets with 3/8" bar stock welded in, so in case it ever wheelies too hard, I just don't want it to mash them and restrict my exhaust flow

alright I'm going to swap BTR stage III truck cam in my Z28 for a another lower lift stick, the summit 8714. Then I'm going to get back to work on that Ferrari F40 I've been working on

How do you like the 706 heads on your 6.0L are they stock? I was thinking of putting a worked set on my LS1 with this summit 8714 if it's not enough of a jump for me over the BTR 3 truck I have now, I'm just about to start the cam swap.

Guys I've got the summit 8714 in the car and it is running great. I've been playing with the setscrew on the throttle body and got the car running pretty well, but I think if it becomes to inconsistent or doesn't want to start when hot or something I'll just drill a small hole in the blade so I can close it back some more for better tip in and to keep the idle from hanging. For now it Idles great at a commanded 800rpm swinging only about 50-60 rpm each way, it does sound pretty darn mean and it definitely feels noticably stronger than the other cam above 4k. I can't wait to get back to the track for a new best et!
