I've read all the threads. Seems a GT2-3 is the **** for a 5.3L. Well, I just bought one for my 6L/Radix. I got it mostly to eliminate the overlap in my current cam. I'm running a 2.75" pulley and only seeing 7psi. I want to get the boost back plus it seems that this cam makes good power on a 5.3 so I figured it would be pretty good on a 6L even thought it will "feel" a little smaller. The stock idle is actually a down side for me but I will sacrifice the lope for more hp/tq. Anybody running this in their 6L/radix combo already? How do you like it?

 

There are many guys running that cam with Radixs' over on SilveradoSS.com. They love it, it seems to work extremely well with boost in the 5.3 and 6.0s.

 

i just bought one for my 6.0, can't wait to get the new motor and cam in the truck. All the research i did came up with nothing but good info about it.

 

You'll like the gt2-3,it doesn't really sound like a stock cam,it just has great street manners and it will pull cleanly to 6600rpm or more.You will find some of your lost boost too.

 

I bet you'll be 8-9psi boost with the cam.

 

Anybody have a sound clip of GT2-3 in a 6L?

 

what about the exhaust clip in your sig

 

Try #2. Cuppycake.

 

LOL

 

Are you running on stock Piston? if you go over 6000 rpm. You really have to think about piston not get toasted for big A@$ hole right in the middle.
