Thanks for the input Will what about the SBC DD 3850 Street Comp
6 CB???? anybody running it???

I really dont think I will do much sled pulling if any...I would rather Drag race....I am kinda thinking the SBC 3850 street comp 6 button will be sweet?!?!?!?!? it requires a hydro upgrade and the haisley does not..this makes me think the SBC has a little more holding power?????

thoughts????

I have the 3850 sprung hub 12cb now but had the 3850 solid hub. If i were you I would ask SB about shifting differences between the 6 and the 12. The 3850 is a very strong clutch and will take lots of abuse. If your just drag racing than a 3600 would suit you better. I will advise you that the bigger plate load pressure you go the stiffer the clutch pedal gets. The fastest shifting 6-speeds often do not use the clutch while shifting so also keep that in mind

Thanks for the info.....I was kinda thinking the 3600 would be too small HP rating....I am shooting for around 700hp... and the 3600 is rated for 650hp and the SBC DD 3850 Street Comp 6 CB is rated for 750 hp. Might as well go a little overkill right???

Ive driven a FE and it would only shift when it wanted to, had to wait 2 seconds between shifts. All my stockers on my nv5600 shift plenty fast except the 4th-5th shift. I always have to let off and make sure it doesnt grind.

Dont get a DD that cant hold the abuse of sevral 20psi 3rd gear launches followed by wot shifts.

Honestly I dont think the clutch your looking for exists. One or another has drawbacks. A 3850 DD will hold the launch but how quick is it going to shift. A Hasiley oe 3200 dd might shift quick but can is slip ubtil 20psi in 3rd and then engauge???

The only perfect clutch for us is an

Well we all wish our heavy duty tranny's will perform like a sports car tranny but they wont. If they made a clutch that I could bang every gear at WOT, shift in the middle of a wheel spinning drift at 50mph, be able to stage at 20psi in 3rd gear and then launch it to a 1.8 60foot and then perfectly grab every gear at WOT down the track with zero issues I as well as 99% of all manual owners would buy it!!!

But that will NEVER happen

Its just the nature of the beast

This is why alot of manual owners swap out or trade in to an auto once the've been bitten by the bombing bug, and are tired of being held back by their tranny. Yeah its a great all around truck and has 500hp but its difficult to get good times at the track when compared to an auto, and its difficult to to other type of fun stuff like donuts, burnouts, off the line races. Not to mention drive train/line shock, and lost boost during the shifts.

The only time my truck can really shine is on the freeway after I'm done rowing the gears through 6th. Only then am I able to compete...70-110 in a blink of an eye

I will never own another auto
but I will make my standard as fast as I can for a standard

personally when i upgrade my DD in the spring i am going with a spec....drove a truck with the spec DD in it and all i can say is wow, pedal feels the same as my sbc, but it is way quicker for shifting.

is your SB 12 or 6 button???

IMO the 3600 would be plenty of clutch if you are not gonna hook to a sled, but I am with you, overkill is just about right. I kinda wish I had the 3850, not that I need it, just for the insurance.

Mine has held 3rd gear burnouts with the 4 34x12s so its pretty stought, zero slip to date. If you have any questions Mark feel free to pm or call me and I will tell ya what I know.

ramtd02

my sb is the 12 button..

53 willys

Will, thanks for the offer I know you do your homework on mods so it's nice to know I can call you and get some more opinionhow many buttons did you get?? 6 or 12??





I called Peter today and told him what I was going to do he told me to get the SBC DD 3600 Street Comp 6 CB...when I asked him about the 3850 6 button he said it would have to much flex...and would not shift as fast.
he said I should have no problem with a 3rd gear launch even if I was pushing 750hp Peter said I could hook to a sled (limited number of times) with this clutch but I would NOT want to slip it the whole way down the track or it wont last


still really tough decisions
Banshee kinda has me liking the HMR but his is on a NV and my truck is a G56..so they could shift totally different anyway...

it's too hard of a choice...and I just want to make the best choice the first time

thanks for everyones input

Mark, no problem, I know there are guys on here know a lot more about this stuff than I do but I am more than happy to help if I can, and the offer stands, anytime.

I got the 12 button as my truck tows a fair amount and it is a DD more than a drag machine. It seems the 12s just have a little better manors than the 6s BUT I have NOT driven a 6 so this just from what I have been told, the only first hand expierence I have with these clutches is with the 12s.

Also one G56 may shift differant then the other too, and FWIW I ALMOST went with the HMR, Curt (sp?) was really helpful but like I said the springs are what did if for me on the SBC and I cant say enough good things about there service,

Well I pmed some more guys with questions and it kinda sounds like I should try the 6 button 3600......Peter told me the 3850 has to much "flex"...and another member confirmed it. He told me he had the 3850 and it was messed up or something..so Peter sent him the 3600 12 button and he seems to really like it...I just wish some more guys where running the 6 button so I can hear about that..
