Or move the shifter to the floor, or maybe a push button shifter?
As far as mounts...TransDapt makes some inexpensive plates for use w/mounting an LSx when using sbc motor mounts. Since you have a 3sp. you'll need to acquire an inexpensive stock automatic cross member or buy aftermarket. I got one like this from CPP for like $65 I think, along with a poly mount:

Its possible you'll have to get your drive shaft cut/remade? and for a 4L80e a new end put on? Drive shaft should currently have a 27 spline slip yoke? 4L60e is 30 spline?
