About 20 yrs ago the first engine I pulled here was out of my Datsun PU. think it weighs 475# plus the weight of the 5-spd. I didn`t have an engine hoist, but do have a chain hoist.
I ran a 4X6 beam across the celing joists of the old barn. one end I placed a 4X4 under the joist/beam, and secured it so it couldn`t move. the other end sits on a wall that divides the 2 halves of the barn. it is very secure and solid, I used it 2 times before I acquired the engine hoist that I use for the MB`s.
I have always pulled the engine and transmission as a unit.
This is not exactly the safest way to pull an engine.
