Not built for racing, but built for off road. She is going into my F250 4X4.

While we are talking about this, I have been wondering about the engine drop. They sell those plates that bolt onto the intake where the carb goes, to allow for easy pick and drop into engine compartment. Is it safe to pick up my 460 by an aluminum intake? I am afraid she won't stand the weight. Ever used one of these gadgets on a HEAVY engine?
