77 grand prix engine swap.
 
hey, i have a 77 grand prix with a dead 400. wondering if a 350 out of a 72 buick lesabre will drop right in. well as far as the motor mounts, exhaust, etc. any direction or help would be greatly appreciated.

ok. went to do the swap. the tranny bolts up, but the rear trans cross member needs to come forward about 6 inches to the front set of holes in the frame. it also looks the oil pan is going to hit the front cross member. i was told that a skylark oil pan and sump are needed. does anyone have any info on this?
