I've seen at the GMC dealer i used to work at, a 2004 Sierra 1500 swd with a 345 horsepower 6.0L.... I also went to the Houston Auto Show where they had 2 Silverados "Performance Editions" with the same option. I cannot find any info on the internet about these...... Does anyone have any info on these???

Got any performance mods on your 4.3? Ive got a 99' Blazer 4x4 with a little list and some spray.

 

yeah i have a few bolt ons, havent put spray on it tho....

 

Thanks for the info guys...

 

I have a 2600 stall, K&N intake, TB, 3" Flowmaster Exhaust, E-Fan, 160* stat, descreened MAF, and a 75 shot to yank it out of the hole.

Have you ever found any good performance sites for S10s/Blazers? Im trying to get a section added here just for 4.3L performance. Recently ive found alot of big cams, and engine components to get alot of power out of my Blazer, just wish there was a good site to share and list info.

 

i tries a long time ago to get one added here too, but that didnt turn out so well.... so i'm at www.s10forum.com theres some good knowlege there.... performance sites as far as advice or parts? the satall you have out of the trailblazer/envoy? what times you running in your 4.3? 15.39 is my best.... mods include...cai, gibson catback, hpp3, march pullies, 1.6 rockers, t-bady spacer, and descreened maf.... not sure what i want to do next tho...

 

Its a TCI 2600 stall. Whats cai? How high can you up the rev limiter and how much firmer does you truck shift w/HPP3?

15.39 is pretty good for a Sanoma, is it Ext.Cab?

Throw a 75 shot on and you might hit high 13s with traction.

 

Cold Air Intake

 

Makes sence.
