Radix would be the best based on your criteria.

 

I am located in Springfield Illinois.

 

After looking at both setups I will probley go with the radix with a 2.9 pulley. That ought to trash that 4l60 fast. I probley wont hit the 480-500, but I guess 450 is manageable maybe a little more, the mods I have are....

Edelbrock TES headers, 214/220 .600/.532 115 lobe cam, ported oil pump, JWIS timing chain, thunder racing pushrods, and 918 springs, KN FPIK, Borla exhaust.

I just want it fast enough to beat some chipped and pulleyed lightning, and a occasional SRT 10. Maybe some Mustangs or a Cobra.

 

Oh yeah it is a RCSB that weighs 4226, without me. I will need a new trans but that just gives me a reason to get a 3000 stall. I thinking about some 3.90's and a Auburn as well.

 

Those headers might give you problems.. I have never seen Edelbrock headers work well on the lS1 cars so I doubt they work well on the trucks in high HP projects.

 

That is good that you said that because I dont have them yet, it is going to be this years Christmas present. So any other suggestions? I really like the Thorley headers, but I dont know if they have the problem solved out with the driver side header hitting the stearing shaft. I know TOG's and ASM are the best but they are so damn expensive!

 

Please don't take my word as gospel but I know for a fact they suck on F-bodies, I would assume the same on a truck.

I really liked the AS&Ms

Decide what type of forced in duction you want then go from there. Because turbos wont use any of the headers used on a normal setup.
