Need help pulling my 273

Not sure about the P/S, but...no, a slant won't bolt to your V8 automatic.

Good job on getting the engine out.

I'd also make a suggestion on the block: take all the freeze plugs out, take the drain plugs out (should be a pipe plug on each side of the block) and start flushing it out with a garden hose. A lot of times there's so much sediment in the block that you might need to "scoop" at it with a long pick or a bent coat hanger, but now would be the time to see if you can't get a lot of it out there. Drain the block of as much water as you can after you flush it so it's ready for a 50/50 mix of coolant.

If you're going to keep it out and rebuild it, then you don't need to worry about this. A good hot tank soak will take care if it for you.
