I would guess the engine weighs 400 lbs. The valve cover bolts will work. Or you could take off the head and have it that much lighter. I just installed a WD engine without the head, using short 2s2" angles bolted to the holes for two head studs, studs removed. You don't have to move the pedestal forward, you do have to move the steering shaft out of the way. Take off the universal joint from the pedestal shaft and maybe the steering shaft from the steering wheel and get the steering shaft out of the way and the engine will come forward enough to tip the front up and clear everything. Oh, got to take the support for the crank off of the pedstal and pull the cranking shaft forward too, to get room to pull the engien forward. Check your copy of an AC manual, but this is basically how it is done.
