nice work Mark, I ve been wondering where you have been as well.
General uhp's should be a good tire for you.
Any comments on the afe vs vararam? I still haven't changed mine.

 

hey allgonoshow, how well does your 6.2/6l80e/3.73's work on the street. Sorry to hijack the thread a bit. a 3.42 seems like a pretty good choice, i would imagine the 3.23 gear would be similar to a 4 speed with 3.73's.

 

Mine has the max tow pack, so came with 3.73's.
My summer tires are yoko spec x, 285/50/20.
It will break em loose a bit, but not alot from a dig and chirps em on the 1-2 shift.
Sounds like Mark may have a better tune dialed into his.
3.73 should be better from a dig.
Where it shines is 2-3000 rpm kick downs, absolutely rips on a wot application 60 mph and up.
Tows well too.

 

The Vararam is nice when ur @ cruising speed but those 5'' scoops also soak in heat when you parked or idling. IAT's are lower with the AFE, especially coming out the hole...

 

36-38mph but i shift at 6500....im still in the tuning process. i need to see where i like my truck to be and such. i have 17s and DRs which onces you wanna borrow if i dont like the 4:10s imma go up to 3:73s.

i still want 1 7/8", i like the 3500+ punch

 

I see, that top end CAM extends your time between shifts...It's all about matching parts...If I had shorter intake runners like on a Camaro I would have gone 1 7/8' or if I wanted a top end CAM like you...

Hey, yall going to No Problem when they open back up?

 

Would be interesting to do a direct, back-to-back comparison on the same dyno.

Compared to your deal - I'm running larger tube headers, but no UD pulley, stock cat-back and stock thermostat. I'm also running LARGE, heavy tires - P305/50's on Yukon 20s.

I have been considering letting Pat G spec a VVT cam for me . . .

I too would LUV to run a 12.999 with stocker cam, but don't believe that will happen without a high-stall converter. I'd like to scale my truck - both times I've raced it the scales were closed. GUESSING 5800# with my fat butt in the seat.

I know it's a LONG trip from Lafayette, but I'm going to Nelson's truck race at San Antonio Raceway in February . . . any way you could make that?

EDIT: Mark - what have you set your WOT upshifts at?

 

Yes it would be nice to do a back to back comparison to see what these trucks like and share with everyone else. The only way to get this brick out the hole on stock stall is bottom end, that's what i'm playing around with now using the 1 3/4's and VVT. If I can nail some 1.8 60's it may be worth 12.999...We shall see if my finesse foot is up to the challenge...I'm gonna have to find a lighter, shorter, and sticker wheel/tire combo...

My 1-2 upshift is set for 6,100 rpm, 2-3 is 6k rpm. I finish the 1/4 at roughly 5,800rpm in 3rd. My 3-4 is also 6k rpm when i'm feeling brave... After each shift i'm landing 200 rpm b4 peak Tq approx 4,200rpm...

No can do on San Antone... I may be around Houston soon...

 

UGH, make me want a 6.2 SOOOO BADDD

 

Thanks for the WOT upshift info - I'll prolly have Pat G set mine at 6K as I worry too much about bent pushrods rocker needle bearings falling out, LOL!

Damn - 1.80 60s??? I wish, LOL! Admittedly before any tuning, my 60s at Nelson's deal last Feb were in the 2.2s - and back then I was running the stocker 275/55 tires!!! I suppose I need to borrow some 17s with decent tires for the track . . .

If'n I run it with my current 305 tennies, I'm hoping like he!! I can run a mid-13.
