No, not at all. I just bolt 1 piece of chain, diagonally, & place the hook close to where the carb mounts. You can easily change the angle, by moving the hook along the chain. You can insert screwdrivers in the chain, on each side of the hook, to keep it from moving.
The pics show how I installed a 455/TH400 into my last 2nd gen Bird. Didn't even jack it up, for the initial install.
Because the nose stuck out so far, the arm wasn't long enuff. So, I grabbed up a handy piece of round pipe to make an arm extension. Actually made the arm longer than it had to be.
If a longer arm makes it too front heavy, there are lots of ways to add counter weight to the rear of the hoist. Obviously, the safest way to do that would be to get it weighted correctly, BEFORE actually putting the engine/trans over into the engine bay.
I'd pulled a 455 out of my '74 Ventura bracket car, with this same hoist, without needing an arm extension. But, the Ventura front bumper didn't stick out as far as on the 2nd gen Bird.
Back in the old days, I pulled/installed engines with my Dad's chain falls, hangin from an overhead beam in my old shop. But, the hook-up to the engine I used was the same.
