i bought it for my last truck. i now have an 03 scsb with a 4.8. i'm looking to get mid 13's out of the truck. i'm thinking of buying an ls1, installing the cam and stall i have along with a locker and 3.73's. will this get me 13's? will this be more reliable and easier on the tranny? i don't mind the work of an engine swap. will the stock injectors support it?

 

bottom line....anything more than stock (and sometimes stock) is hard on the trans.....

 

sell it to me but really, i would think you could do a 6.0l and keep the radix and install it on the 6.0l if i am not mistaken

 

I like your idea best

 

On the trans thing I blew mine with just intake exhaust and tune

Radix and 6L would be more civilized for a DD app IMO. Plus the instant torque will help out the wimpy 4.8. If you dont mind me asking why did you get rid of the Denali?

 

i got transferred to Houston at work. its alot more expensive for me to live there so i wanted something paid for.

 

Having a regular cab that ways less is also easier than a crew cab, probably like a 1000 pound difference.

I would install the radix on the 4.8 for now. That would give it more torque and horsepower than a mild bolt on 6.0. I would think just the radix with stock pulley would be good for 13's. My 5.3 ECSB weighing in at 5250 with me in went 14.09 with just the radix. I dont see why you couldnt get in the 13's with slicks.

 

6.0 and a radix, I'll have to try that out.
Since you have the radix I would put it to use. If you want to do the work of a swap, cam etc...go for it and sell the radix to fund it. A RC truck with a Radix/6L would be fun for a DD.

 

there's a couple of guys here running 13's with a n/a 4.8

 

Either will get you 13's - Vicred has a cammed ls1 in his RCSB and runs mid 13s on street tires I believe.
