Swapping A GM 4.8L V8 Into A 1987 Jeep Wrangler - Four Wheeler Network
You’re looking for more power out of your Jeep and your buddy suggests the tried- and-true engine swap to transplant V-8 power. So, you pull your trusty, but tired, inline-six engine out and bolt that V-8 in over a weekend. But six weeks later, you’re still riding the bus and bumming rides from friends as your Jeep sits idle under your carport. Truth be told, proper engine swaps require good planning, plus more time and money than almost everyone expects. 8L V-8 is the smaller cousin of the very popular 5. 3L engine found in so many GM pickups and SUVs. So, many details of this YJ swap can also apply if you’re dropping in a 5. 3L or 6. 0L Generation III truck engine. The Vortec LR4 engine is a small-block engine used from ’99 to ’06. It’s the smallest Generation III truck engine and runs a slightly shorter stroke than the very common 5. 3L engine. For this swap, only the complete engine was purchased because the Jeep already had an AX15 manual transmission that was going to be retained. Advance Adapters offers a fairly comprehensive set of swap parts to do this conversion, and many of those parts were used for this. Source: www.fourwheeler.com
