IM installing a stock bronze pilot bushing in my steel crank 383. Its very tight going in..I was going to heat the crank a little bit and then freeze the bushing,but then i got to thinking.

Are all factory steel crank 383's drilled to fit pilot bushings? And if they werent drilled would the hole even be close to the size that you think you would be able to drive a bushing into?

Can I just remove some material from the outside of it?
