Reply to "motor lifting plate"

Carb bolts are 5/16 thread- sometimes coarse, sometimes fine thread depending on what intake manifold you have. Fully tightened, the lift plate with four bolts should hold OK. A fully assembled 351-C weighs 550 lbs without the carb, flywheel & clutch or A/C compressor which can be laid in the passenger compartment without disconnecting anything, and the rear AC condenser laid over on the right rear fender on a blanket- also without disconnecting.

Add 30 lbs for a stock flywheel, 20 lbs for a clutch, 15 lbs for a bellhousing, 12 for a Holley 4bbl and 155 lbs more for a complete ZF, making the assembly as lifted around 780 lbs. It's a really good idea to NOT get any human body parts anywhere near the thing as its coming out or going into a truck bed, if things go wrong....

Some guys pull at least the distributor cap or the whole distributor, as the powertrain assembly often tilts while being extracted and a common occurence is a distributor cracking the rear window. Good luck.
