From Old to LS Power: 6.0 Swap in My 1977 Jeep J20 (Part 1)

What happens here

First, use a ratcheting wrench to bolt the transmission/transfer case cross member into the frame of the Jeep J20. Then, secure the first part of the LS swap conversion engine mounts to the frame. The narrator experiments with different bolt holes, aiming to position the engine as far forward as possible, believing the LS engine to be slightly smaller than the original. Insert the engine mount bushing into the bracket.

Goal: Mount cross member and engine mount brackets onto the frame

I don't know what I don't know what holes to use. I don't think it matters. I'm going to move it as far forward as I can. I think because the LS is a little bit smaller. I think it's smaller than the original engine. I need the backing on there. These uh these mounts are a little pricey. I think they're like 220 bucks or 250 bucks all said and done, but great quality mounts. I mean, BG always has great quality stuff. Really like I've never had a problem with them. Fast shipping, great customer service. I'm excited I'm excited to show you guys this this engine. I've been keeping it kind of a kind of a little secret for a while. I've I've had the engine for probably Oh, when did I go pick it up? December, maybe? And I haven't posted anywhere online yet. I'm excited for it. Um these are on. Now it's time to pull the engine out of the corner of the garage and get the flex plate bolted up. So,
