i have a 350 going into my RS. i bought a pilot bearing today. but it doesnt fit my crank . i called Advance Auto Parts (where i got it)and told them i needed another. They said that GM made the same bearing for all vehicles/engines from 1949 to 1989!!!!!! i looked at all the other cranks laying around my garage (350, 305, and 327) and it fits all of those!!!!
Turns out my crank is missing the small beveled edge around the hole where the bearing will normally go. Was this crank only made for automatics????should i use a dremel to make an edge? And even if I make the edge, what guarantee do i have that the bearing will even fit? It seems that the bearing is VERY slightly bigger than the hole, so even if i make the edge, why would the bearing even fit? Ive had so many delays from this thing, it better work when i turn the key. (just venting steam again)

 

Yes it will fit.

Yes that is correct, they are the same from past eternity into the future and beyond, except for certain 265 & 283 cranks for cast iron Powerglides. I doubt you have one of those, they're pretty hard to mistake for anything else.

It is an interference fit, about .003" - .005" IIRC.

Just put it in, don't worry about it.
