s10 2.8 to 4.3 swap

i have a 85 s10 with a 2.8 that i want to put the 4.3 into. a buddy of mine just rolled his 91 blazer with the 4.3 tbi and is gonna give me the thing if i want it. so im takin it, but i need to know whats gonna be needed to get it going. i dont want to deal with makin the TBI work anymore, i am thinkin about gettin the edelbrock intake and a carb and just run it that way. but im not sure what to do about the motor mounts and the tranny mounts and driveshafts. i already swapped the 2.8 out for another 2.8 so it was veeerry easy. any help with what to do for the mounts and stuff would be very helpful. thanks in advance
