I decided to tear her down today. I need to get the loose converter tightened and I have a new Magnaflow waiting to be installed.

Plus I am skeered after seeing the recent pics of driveshaft woes, so I am going to upgrade that while it is down also.

I took the converter out today and it is probably a good thing-I see scorching of the paint in the front where the clutches are. I think I know where the excessive flash I was seeing on the dyno was coming from now. I am hoping Yank can do something to make the clutch hold my power, otherwise I may go with a Precision like Parish did. I am sending it off on Monday, so I am anxious to see what they say.

I am hoping to have it together and ready to go for Super Chevy in Memphis in about 5 weeks.

 

Thats probably a good plan. Much better to dear it down for preventive maintenance than having to fix broken parts.

Take some pics of the Yank.

 

I will snap a couple pics tomorrow before I box it up. Has anybody on here installed a pinion yoke on their 8.6 rearend to accept a 1350 series u-joint? I was told that one for a 8.5 wouldn't work because of a seal issue. I researched the spec section of the rearend book at the parts store this morning and it looks like the OD of the pinion seal for a 8.5 is the same as the 8.6 but the ID is different. I think a 8.5 yoke would work if a 8.5 pinion seal is used. Anybody else run into this?

 

get a good driveshaft made.......may save you some trouble in the future

 

L-Eater,if you go with the Vigilante it works with the stock 4L60E flexplate,that's what my Tahoe is running now is a 10.5" 3 disk Vigilante.

 

I have been hearing afew people having troulb with the yank convert not holding up
like they say they will.

 

what was it flashing to?

I have a 1350 pinion yoke on my truck. no problems with leaking. i just called allen and got it from him if i remember correct or maybe he told me to call dennies. actualy i think i got the yoke from dennies.

 

BadZ-the order for the new shaft is going in tomorrow!

Whitt-so the precision only has 3 bolts? I already have a 6 bolt flexplate monkified to fit the Yank. But I can always get another 4l60 one if I hafta.

Sleeper-I could brake stall it to 4500 just sitting in the driveway-WAY too loose. I am hoping for so ET improvements when I get it dialed in. So you just put a 1350 series pinion yoke on without any issues? Cool thats what I wanted to hear.

 

Cool ill have to make the trip down there to get some spy photos of L-EATER's intercooled whipple .

 

yea it actualy came with a new pinion seal. the only thing that is remotley leaking now is the diff cover.
