i welded a comealong to my hoist near the back and run a pulley by the main chain point, i can chain the engine loose on the back and tight on the front and use the comealong to take up the slack on the back chain, if i need to drop the back end like to get a engine/transmission combo out i let out some cable till the back end drops to whatever angle i need, and when it's out i can suck it back in and level it back up, ill try to take a picture if i can remember, been using this for years and wouldn't have it any other way, tried one of those leveling bars and hated it so i came up with this, maybe it works better on v8s as it didn't work worth a crap on bmw I6s and volvo I4s, been hanging on the wall for atleast 7 years
