for anyone wondering how to move the stock 4.3 or want to install a sbc, and dont think you want to build the super simple engine mounts skymangs shows, I have recommended and just recently installed for the first time the universal weld in engine mount crossmember from speedway motors. It comes with two new motor mounts and is $75.
to keep the motor at the same height as stock, I ended up with the tube almost exactly 1/2 way over the frame then boxed in the open end. you can measure from the center of the original mount to the center of the new mount to get the right amount of move, mine is moved 10 inches because its a 41 going on the frame, measure your own to be sure. also, dont forget to offset about an inch to the passenger side for steering shaft clearance, and install the mount at a 4 degree down angle. you dont have to level the frame, just put an angle finder on the middle part of the frame and note the angle, then install the motor mount with 4 more degrees down to the rear

what about the trans? what if you dont want to section your original or dont have it?
speedway makes one of those too. get the one with the 4" drop, I got the 2" drop and it wasnt enough for exhaust.

you might need to cut the center of it out to fit a later trans mount.

it comes with two triangle mounts, but so does the engine crossmember, if you use them all on the trans mount you have a removable trans mount, easy peasy.

if you order them at the same time you get free shipping, and its under $130 for both WITH new engine mounts. you can build them like skymangs shows and its not very hard and is defintely cheaper, but I spent more time at homer derpo getting the parts to make my own on the last truck than I did installing BOTH of these
