Just started today. Got really noticeable this evening. When the clutch is disengaged it rattles quite loudly. Can feel the vibration in the pedal. Engagement hasn't changed, shifting hasn't changed. Thoughts? It's a 3600 DD sprung hub I believe. It's the new "quiet" style. Has about 50,000km on...

Well I picked up a 91 GMC CCSB 4x4 with a 1992 12v in it. Was the a518 the only auto available in '92? Discussing with a friend of mine it appears to be a 727. There is no connector on the case for the o/d. Here is a pic of the tail housing to help identify it. Also this trans has a really...

Picked it up yesterday. 91 GMC ccsb. 92 12v with A518. Leather seats out of a ford. 6" lift 3" body. Sitting on 35's with 20's. Without overdrive averaged 17.8mpg at 70mph on the way home. More pics to follow.

So I've been running zach's pushrods and springs for about two years now. A few weeks ago, I was puttin my injectors in and one of the pushrods must have popped out of the tappet. Fired the truck up and it had a terrible tick and rough idle. Pulled it apart and found this on number one. Called...

So today I was putting my 90hp nozzles on my brand new injectors. Got through 4 of them and then noticed a small little metal disc. Took another nozzle off and this disc(shim?) fell out as well. It fits into a bore in the pressure pin between the nozzle. What is it? Also if one fell out what...

So it's happened a few times before, but really became apparent tonight. If I do a 1/2-3/4 throttle pull in 3rd or 4th an then step on the clutch, after a few seconds of coasting the truck dies. Watching the rail pressure gauge it drops off to about 4-5000 and then the truck dies. Fuel pressure...

So I had my injectors out awhile back, and when we were putting them in my buddy noticed something. When I started the truck the upper rad hose became pressurized fairly quick. If you try go open the cap it bubbles out. He just did a headgasket and studs on a 05 dodge and when he fired it up it...

I'm looking into running some 33x12.50x17 tires on my dually. How do you determine what size of spacer to use between the duals? Currently running 265/70/R17's without a spacer.

Well since it my injectors back from testing, and having my stock tips puts back on ive had an rpm issue. I used two good used injectors from a friend to replace my two bad ones. With my smarty loaded in the lower revs my rpm's seem to hang. Slow to drop and then truck idles at 8-900rpm instead...

Curious if anyone has seen a truck melt 5 out of 6 pistons in one shot. We dyno'd a friends truck yesterday and went we pulled it apart, thats what we found.

So today I go to put my injectors in after getting them tested. Two of mine have bad delivery and return rates. So a friend has two good(tested) used ones. We get them all installed, get the connector tubes in. All the lines. Start putting in the solenoid wires and we notice that ine solenoid is...

So someone told me that the settings for TNT-R are different from the other smarty software. Is this true? Can someone tell me the difference? I.e. timing(1-4) and so on........ Or am I just wack and it's all the same?

So I've had this problem before where if I accelerate hard at low rpm my truck starts popping and I get white smoke, it hasn't done it for a long time, but I recently lowered my smarty setting to sw-4 from sw-6 to try to get better mileage. While on sw-6 I never had this issue. I've got some...

So i recently installed some used ddp 90 horse nozzles on my 04.5 cr. I'm running an arson III and smarty beta 4.2 programming. This thing has mad injector rattle now and it is super annoying. You can't even hear the truck over the rattle when accelerating. It goes away around 2200rpm or more...

So i'm needing a new clutch for my truck the single thats in it is starting to fade out. My truck is going to be right around 600hp (twins, 90's, arson III, smarty) so i'm wondering if a southbend 3250 will be enough or should i go with the 3600? i mostly use my truck for daily driving and...
