I bought it for the has mileage... Now I want to have the power side. I'm looking to do a V8 swap. I know a guy selling a 5.2L V8 out of a 1994 Jeep Grand Cherokee. I did some looking around & come up with on average 14-16 MPG highway & 11-13 city. I drive 20 miles a day just to go to school. 65 for 3/4 of the way. I have the automatic 4 speed, & won't change that. Last time I checked with my inline 6 I got 18 mpg. My YJ is a lot lighter than a Grand Cherokee though, & only has p235/75/R15 on it. You guys think it's worth it? Will the motor bolt right in, or will I have to get different mounts? I've only done motor swaps from S-10's to other S-10's.... Thanks a ton
BTW: With 3" dual exhaust, no cat's, would it help on gas mileage for the V8?
