Yeah, you don't have to pull the tranny with the engine but that is my preferred way to do it. That way I can take the tranny off and put it back on while it's on the workbench instead of me breaking my neck to get it off while oil is dripping on my nose. Sound familiar? JamesW has the preferred method to hook up the engine and tranny, but you can also get a plate that fits where the carb bolts onto the intake and pull it that way. There's more than one way to skin a cat.

 

I've seen those plates that bolt to the carb studs, but I've always been afraid of use one. Afraid it would strip out and fall (yeah..unfounder fear, I know). Plus it's hard to tilt the motor from that single point.

I like using the 4 corners, but you have to be very careful when rotating to not put the distributor (if installed) in a bind. It can easily be damaged.

The load leveler is a really nice option...just crank in the angle you want...no fighting it. I've removed and reinstalled several times by myself using this.

 

Like I said, your way is the preferred way, but it can be done several different ways. Either four corners or criss cross corners works too. My first engine pull many years ago was with a three legged puller. Needless to say, I learned from that dumb assed mistake.
