I have used 4x4x4 blocks with a 4x4 between them to support blocks at the edges and clear the crank.
I usually position at a main so that I have more clearance to move the crank if need be.
Generally I use a bottle jack but I have used a floor jack on occasion.
For safely I will position a jack stand at the front of the engine with a piece of pink foam insulation on it...just in case.
I've used this many times outside the shop over the years on all sizes of engines. (in the shop I have made up the metal equivalent using 2x4 square metal tubing)
