What engine? If it's a V8, doesn't matter what brand, you'll need intake manifold gaskets as well. If it's a Dodge 5.2 or 5.9 Magnum, I have a serious recommendation for you, since you'll be in that far. If it's a Ford V6, it's a pain in the Arsehole. If it's a Jeep 4.0L engine, that thing is a piece of cake. What you're in for depends on what you're messing with, brother. Some can be a serious nightmare, when done in the driveway.
