Auto to Manual trans question

I'm putting a Tremec 5 speed in my 68 Bird and was wondering if there is anything special I need to do to get the pilot bearing into the crank. The car originally came with a power glide.

PLEASE don't tell me that I have to pull the crank and have it drilled!!!!

Nice choice!  This trans has overdrive as well.  I actually ordered one for my rebuild as well, but because of an extraordinary leadtime and the fact I already paid the bucks to have my TH400 rebuilt, I stayed with automatice.  I hope I don't kick myself for it.  Unfortunately, I don't know for sure since I didn't do it, but regardless it will be worth it IMO.  Good luck.

I went with a nicely used 3550. It was a really good deal that I couldn't pass up. If I ever exceed the torque rating I will have to step up to the newer TKO600, but with street tires I think I'll be fine.

It is listed as a constant 450ftlb torque rating. The new TKO600 is listed at 600ftlb. I'm sure it's plenty strong for my street car.

Is it weird that my pilot bearing slides right into my eagle crank with no resistance??

I have read that some cranks were not machined for pilot bearings.  Frown

BOP has the correct size bearing.
