WOW!!! Sounds like a sick *** GN.

 

Nice times Yellow. We should meet up sometime since you aren't too far from here. I'd love to see how your truck runs. You still gonna be going out to Commerce in February?

 

Yeah I'll be there you should come by. I think my new tune will be in this week from allen so that should take off a few tenths but yeah I cant wait. Maybe we could line up your Yellow sierra vs. My Yellow sierra. J/K .

 

LOL, you'd hand me my butt. But yeah, I'll line it up with ya. Nothing like some good ol' racing fun. I mean I lined it up against my dad when he drove my Formula, and I knew it was no contest. It's still fun though none the less.

 

Right on man! I like the my EC but everytime I see a RC I cringe at the thought of how fast I would eb with the sam mods in that truck! LOL! It makes the challenge of going fast a little harder with the EC and I kind of like that now that I have on! What made you go with a Whipple on the LS1? Did you buy the 5.7 new or what? What cam are you running?

 

I like the whipple because of its instant boost and I just like the twin screw design. I bought the LS1 used and built it with diamond pistons and callies H-beam rods. It should be good for 15psi of boost. I'm running a lunati cam with 558/558 lift and 221/221 dur. it sounds really sweat but I'm going to have to get some quiter mufflers. I like it wihen people think its just a regular GMC truck so I think I'm going to put some quiter mufflers on it.

 

Sweet- Go with a single Magnaflow that my plans! Thats a pretty streetabel cam with the LS1 huh?

 

Yeah its not to big but I bought it when I had my 4.8 so I guess it will do. I think it has a nice power range.
