Need a little feedback/help

So... I plan to put a 360 into my 1985 d150 factory /6 truck

I also have an all original 1982 W150 318 truck The drivers side frame mount on the 85 /6 truck seems to be quite a bit forward than than the 82 V8 truck
Anyone ever perform this swap? What is needed for motor mount brackets? if anything

Thank you
