Crank pilot

Does anyone know what size crank pilot is on the steel 429 truck crank
, I'm hoping it is 1.375, but I haven't measured it.

mine is 1.850,sorry .i dont know about all them.what you got goen on?

I believe all of the early stuff has a 1.850" pilot size. IIRC, after 1972 is when they went to the smaller 1.375" pilot size.









Doug...

Then I'M screwed. ,...... does anybody know where I can get one of the shims, or whatever they are to use a 1.375, in a big pilot size?

If you have access to a Lathe, make one

Easy to make Harold,

I got a lathe we can GIT-R-DUN , gonna rain all damn weekend

I called Coan, one of the tech guys said to use it as is, just put it together, and tighten the flex plat to the convertor, and go with it, you guys agree, or should I pull it back apart.?

Get with Mike (BigDog466)....he can hook you up....all you need is enough room between the front of the converter and the crank to slide the sleeve in....don't have to pull it all out. He is right....gonna' rain all weekend.
P.S.-I have ran without one before for a while...prolly not a good idea though...lol.

Has he got a shop, or someplace to do it, I would tow it to his place?

I don't think you would need to take it there....just take some good measurements with a set of calipers and he should be able to fix you up....or at least get you close enough that a little polishing will make it slip in....he is pretty sharp.

you dont want to run it without the ring on it.the best thing that would happen is the bushing in the pump gets beat out,then the leaking starts,and you dont even want to know the rest.

Wonder why coan would tell me that, they piss me off.

I won the Bash 2 years in a row without one in my Mustang Harold . I used the one I had in the Tbird , i just started all 3 bolts in the convertor and flywheel without snugging them down and rotated it to try to center as best as possible .Then tightened them . I don't recommend it ,but it can be done.

i'm sure an sfi flexplate would help if you did run it like it is,less flex,but it's too easy to fix to not.i dont know why any trans company would tell you to run it,unless they would like to sell you some parts after you shit can your's.

I sent a message to big dog, Maybe he will make me one, then I am going to e-mail coan, and tell them what I think of their info.

Who did you talk to up there Harold?

Tree,
It wasn't Art, what do you get dealing with a bunch of chebby guys------- nutun

Harold's all set up just come and get it.

Be there tomorrow, you guys are grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrreat., be there at "sex"

I'm pretty sure he said his name was Craig, "Tree"

I've dealt with Craig quite a few times over the years...it kinda surprises me that he would tell you to run it like that. Sounds like Mikey has you fixed up...you better be sure to give him a big wet kiss.

I don't know about all of that, I will buy him a beer or ten though.

Harold, I have never ran a pilot spacer. Been running 598" BBF/PG combos since '96 and have never had an issue.
Although I have ran others, Coan has always been my converter of choice.
