I will do a motor when this one blows, there are plenty of 400+ and 450+ cube motors at my shop but i think its cooler to have the fastest 4.8, its already the fastest n/a 4.8 i have seen on the internet and also has the highest dyno numbers for cam only, I shift at 6800rpm and its a custom grind that we cut for 4.8 experimentals... seems to do the job, The tfs heads im trying have never been used and they are supposed to be bad ***!! Ill have results up about them when they go on but if they net me say 40-50 at the wheels that puts the truck making 380 to 390 to the wheels on motor then i can hit it with gas and make close to 450, but i like to stay away from the gas when possible

 

maybe its the sound of the converter locking up?

 

no its the gto next to me i never lock the converter

 

I get what you're saying... but the reason there's not many modded 4.8s around is that for most people's money it's better spent with a 6.0 swap. Spend the same on a H/C/I 4.8 as a cammed 6.0 with equal or greater results and more potential.

Regardless, nice results!

 

Oh it will get a motor i just dont see why i shouldnt blow this one up first lol I wanna see how much i can squeeze out of it and also do developmental research on how much it will take... Who holds the record for n/a 4.8

 

LOL, good point!

Not sure who has it? I'll check the FTL.

 

it goes
13.0 >> you
13.2 >> 01thunder a couple years back
13.3 >> me

im pretty sure thats how it stands now, unless there are other crazies putting a ridiculous amount of time and money into making a 4.8l "fast"

 

what size/stall speed verter you runnin?
nice times, truck sounds great.

 

 

Gator ran a 13.35 as well.
