I have put a 292 into two different '64 Chevelles.
I used the Chevelle oil pan, oil pump pickup, and dipstick.
(Can't speak to other model pans fitting)
The clearance between crank and pan, and between crank and oil pump pickup need checked. Be sure to properly tighten the clamp to the main cap bearing bolt.
