lowering a 383 into A-body

Honestly,
I'd just take the time to figure out a dolley system and use the engine hoist to raise the front of the car. It seems so much easier to put the motor in from underneath. That's what I plan on doing in the next month or so.

You be it is! I still remember my first motor installed in this manner,440 into a 68 Dart. Went in like butter.

That's the way the factory did it,and I totally get it. Sooooooooo much easier!!!! You can assemble your entire drive train,and headers,then just lower the car onto the motor /K frame. Quite a bit safer this way as well.
