I have come to the conclusion that no matter what I do to this god forsaken 5.3L it will never be as fast as the 6.0L with the same mods. I thought I could at least come close but the 6L just makes so much more TQ and HP that I can't compete..

I am running consistant 14.2-14.3@96mph and I still get left in the dust by this pesky 6.0L truck with similar mods. I thought I was doing decent the other day when I raced him a lil on the freeway but come to find out the arsehole was just toying with me to make me feel good!

So just a heads up to those who have plans to go crazy with their 5.3L wussy motors. Throw the plans in the trash and start over with a 6.0L motor. You'll be less frustrated in the end. Unless you live in my area. Then keep your 5.3L so I can be assured of winning at least a couple races.


I'm gonna go find my fuzzy handled ratchet, which I left in my rose colored plastic makup case I converted to a tool box specifically for my wussy *** truck and fix my exhaust leak.

 

dude.... RADIX!

 

are you just blowin off some steam, or are you really gonna swap?

 

Couldn't have said it better myself.

My 5.3 runs pretty damn strong. I will say though, obviously, with the sme mods, more cubes will always run harder.

 

Well hopefully that will be my intentions. All the stuff I am doing to the 5.3 or plan to do will happily convert to the 6.0 later down the road. Good luck though.

 

bang for the buck it is hard to beat a 6.0 swap. yeah GM says it is only 15hp or whatever the ratings are but thats just silly.

on most trucks i believe a 6.0 swap, stall and slicks would be 13's, if you do the work yourself that is about $2000 and your in the 13's, not too shabby.

 

I agree with Parish! Throw some boost on that 6.0, and LOOK OUT!

 

Yeah, I'm blowin off steam BUT I am defiantely gonna do the swap as soon as my Vette sells. I've got it listed in 4 places right now.

I'm gonna swap all the stuff on my 5.3L to the 6.0L. Add an LS1 intake, mill the heads and a mild port job. Depending on price I may do 4.56 gears too.

Of course the NX wetkit I am installing this Tue. will be swapped over also

The Radix would be nice but for the money spent I will be faster with the 6.0L, heads,cam and 150 shot. The Radix would cost me $5k + installed where the 6.0L is only about $1600 and head work is $700. I already have the juice, cam, intake, etc.

I'll be in the 13s with the 6.0 N/A and should have no problem hitting mid 12s on the bottle I would think.

 

Go get em!

 

Not meaning to hijack but if you already have a 4.8, is there anything else you would need to swap? Is the computer ready for it or do you have to bring in the 6's computer too?
