Holly crap those are great numbers. Did you dyno in 3rd or 2nd? Congrats. Are you running an U/D pulley?

 

Dynoed in 2nd and yes I have a powerbond udp

 

Nice numbers! When I was N/A my set up was so close to the same as yours. I had 4.10s. I had 394/365 to the wheels! Congrats

 

Wow. Wish my numbers were any where near that. Great combo. Looks like I need to get this ported TBSS/LS3 TB on there with a UD pulley and get my fuel sorted out. At least I know it can be done. Goal was 400/350rw.

 

What trans does your truck have? 4l60e? If so I just got dynoedand they told me to pull in 3rd... Does that sound correct for the 4l60e

 

I wouldnt chance the stock driveshaft on a 3rd gear pull. Since your a RCSB it shouldn't be as bad because the ds is shorter, but you'll be seeing about 150mph+ on a 3rd gear pull

 

Yes that's what most ppl do is Dyno in 3rd

 

great numbers never dynoed mine wish i had though

 

I need a 5.3 lol...
