293 / 305 on my old 99 z71.

2nd gear pull
204/218 .525 116 cam (2001 LS6)
Borla muffler
Hamm mid length headers
Hypertech
LT1 fans
Home depot intake tube

 

sounds like what I might do on my 05 Silverado

I'm thinking 01LS6 cam and springs, Pacesetters w/ y-pipe, Corsa Catback, pulley, K&N FIPK air intake, and a Nelson tune

hopefully hit 300rwhp

 

With, fresh cam install and ZERO tuning!

226/.535/112 cam, AS&M headers, no cats, stock exhaust with magnaflow, TR55 plugs at .050, TT3000, Volant intake, electric fans, stock 54lb wheels/tires.

With this combo and more tuning I ran a best of 14.29@97mph 2.0 60' and a raceweight of 4900lbs.

 

266rwhp
300rwtq

mods in sig

 

14.415@93.51mph in the 1/4 mile
mods are..
E-fans
K&N FIPK
TCI sf 3000
shift kit
HP tuners
Magnecor spark plug wires.

And a good track

 

How much rwhp are you putting down with your setup?

 

the first set was 318 hp @ 6700 tq was 324 don't rember rpm that was race ready.When got dyno tune it was street ready I had put headers and 4.56 gears.That was the only change. went 338 @ 6700 rpm tq was in the 340 range don't rember I should be getting a print out on all my pulls this week.

 

Dang Randy, you are still making power @ 6700rpm... what cam was this?

I'd like to see those dyno's.

 

mods in sig with the 224-228-581-588-114+4 cam. this was on a superflow dyno thru a 4l80e--301hp and 296tq.

 

looks like Im not that far off the mark then

Im at 277 and 296 hp/tq now and thats with stock manifolds, cats and flowmaster, hopefully open exhaust and long tubes will get me over 300. 350 seems so far away.
