I've put 3 in from the bottom. The first in a 70 B body, the 2nd in a 69 A body and the 3rd in a 72 E body. I use the same engine dolly for all 3 engine installs. Pics are from the A Body. I made a piece of 2x2 box tube that lays on the bottom of the frame rails ahead of where the K frame bolts in. The chain does up to the engine crane behind the radiator support. No need to ever remove the hood. Do yourself a favor and make everything as complete as possible. Install the headers, starter with wires and all of the small items that you don't want to lean over the fenders to complete.
My dolly is made that I can install the transmission mount and cross member on the transmission. As the car comes down that is the first thing I hook up with the 4 bolts through the transmission cross member. Then align the K frame and install those four bolts. From there it's just bolting everything else back up.
