I agree with this gentleman.

LMFAO! i think we need another video of that one.

 

Well....I like the thought that the Radix wouldnt be a waste. If I ended up unhappy I could go with a larger block then. (budget blown) If I could somehow get 400rwhp or so out of that little 4.8L with a radix and some mods I would be happy I am sure.

Thanks for all of you input...keep it coming.

 

I'll throw my vote in for turbo-ing the 4.8

My 408 on 8psi is about equal to kbracing96's 4.8 on 14 psi.

 

i ran a turbo'd 4.8 in my truck for awhile. it ran great. i am 99% sure it would have busted out a high 10 if i had taken it to the track.

sure a 6.0 swap will cost 1/2 what a radix will but it will also give you 1/2 the gain.

my vote is for the radix for more power. or a turbo if you really want to go fast

 

I vote for FI on the 4.8! Mine won't die! It actually runs quite well for some reason.

 

Its the short stroke. The 4.8 is similar to an F1 engine. Anyway, I vote for boost the 4.8, you will break 400rwhp.

 

4.8s love abuse but I'd either cam the **** out of it (Im workin on it with mine) and a stall or FI. Then u can always move up: 6.0.. 7.0.. 8.1. Then boost or cam the hell outta those. Always ways to move up, start out small

 

Boost. I'm on my second FI truck. It's hard to drive NA after having any type of FI.
