Yeppers...I remember doing that on my brothers Camaro, too! At least we did it in the garage...on our backs...with jackstands.
He had a couple of problems with it...so we got really good at taking it out and putting it back in. The best thing we ever did was incorporate one of the "then current" HOT ROD magazine backyard mechanic tips...and screwed in some looooong bolts with the heads cut off...so we could just slide it in (Okay...that sounded weird

)
