chevy 350 swap

I am planning on dropping a 350 v8 into my 87 RAM 50 and was wondering how far it will make the front end drop I have a 3 inch drop on rear and about to do a 2.5 inch drop on front. just wondering how much more it will drop

i read on a different site someone used a 360 and it dropped 1 inch compared to stock. gatta be similar in weight(360/350)
