Advice small block K frame with Schumacher conversion mounts for a big block

I did a 383 in My '69 Cuda convertible, great upgrade from the 360, more torque. I added a Schumacher torque strap to the front of the motor as well. I definitely wish I had taken the cross member out and installed from the bottom. If you go to put it in and it doesn't fit, like I had to do a few times just to re-size everything, then its a pain. Do it the easy way. It might seem like a bit more stuffing about but I guarantee you won't regret it.
