L31 crank

[imiceman44]

Is it the same as an 86 up 350 crank?
I have a 97 that was run with low oil and now has bearing noise and I am thinking new crank from summit and bearings will be faster and cheaper than machining the crank.
Opinions?

Never mind.
I finally got my answer 86-2002 same crank.

Well I thought it was but had no confirmation

So are all 1 piece seal 350 cranks the same?

That's pretty much what I found out.
Corroborated by multiple websites and it makes sense, the change in the vortec was heads and cam.
Bottom end should be same

Yep.

The vortec used a crank sensor, but it read off a reluctor wheel under the timing cover. No changes were made to the crank itself.
