Hi all,

I'm having a hard time sliding the trans back into place. I was told by Amber @ Six Speed Inc. to replace my pilot bearing with a pilot bushing from a 69 Camaro with a 4spd Muncie trans. Problem is, when I try to look it up through the local parts stores they want me to specifiy the engine. Now I understand that the Muncie was offered with a variety of different motors, both SBC and BBC.

Which one is going to work for me? Obviously not the BBC BUT I can't find what I need when using the 350 and 302...

Please help, anyone who has replaced their pilot bearing for a bushing, which part number did you use and which parts store? Nappa/vatozone/checker?

Thanks!

That pilot bushing fits all SBC engines with a GM input shaft .

And the same bushing fits all Mark IV big blocks.

I thought so but was not 100% sure on that so I didn't say it but thanks .

This is the number I use if a customer requests a bushing instead of a bearing. I get them from Car Quest.

The only real advantage I've ever seen from using a bronze bushing over a roller bearing is the bushing tends to wear before the tip of the input shaft does . In a roller bearing application , the input usually goes down when the bearing does . Typically a roller bearing will last 3-4 times longer than a bronze one will .

Thank you, I did not respond because I was busy at work. Didn't really have a lot of time to mess around.

No sir, I appreciate what you said. Thanks for the info. Now if only I can get a part number.


I can't say if I agree or disagree? This will be my first pilot bushing as I've replaced 3 or 4 roller bearings so far.

Not only that but the fact that I always seem to have
trouble getting the input shaft to slide in.

I can get it lined up no problem but it always sticks a little. There is enough room to get some bolts started but thats a big no no IMHO.

So I was told by Amber @ Six Speed Inc. that it would help the input shaft slide in easier AND offer superior longevity.

Well the roller bearing will last longer in your application if you go with an OEM version . These China made bearings you get at Vato Zone are crap . The reason GM and others went away from the bronze bushing is because they do not last as long . Back in the 60-70's most vehicles did not make it to 100K on factory parts . Now days cars are designed to go longer before they need to be worked on (in most cases) . The roller bearing offers a longer life span but causes more damage when it goes down . As for the trans going in easier with a bronze bearing , thats mainly because its a softer metal and even if its not spot on , you can drag the input shaft through it and slightly dig out some material on your way in . Is that a good thing ??? You tell me .....
