V8 swap

I posted this in the Jeep forums as well. Just trying to get all the feedback I can. I was initially comparing the good and bad between a V8 swap and stroking the factory 4.0. Then I got to thinking, does anyone throw a regular carburated 350 in jeeps anymore. It seems like it would take a lot of the wiring and ecm headaches and expense out of the swap.... Just a thought....

ya its a lot cheaper and easier to use a carb than injection. but carbs suck especially off road. carbs can't handle the extreme angle, and nothing looks dumber than a jeep stalling out on a hill and can't get going.

and actually if you already have a 4.0 jeep, stroking it is probably the cheapest and easiest way to go, and it puts out better numbers than a normal injected 350.

im with doc, stroking the 4.0 is the way when the options are a fuelie stroked 6cyl or a carb v8. if you look at the numbers a basic chevy v8 will have about the same as a stock 4.0 anyways

It's really not worth the money to buy a fuel injected crate motor for the swap, either do a stroker kit or buy a totaled donor truck and strip it's drive train.

If you find a nice Chevy with a full motor/trans with all the pulleys, brackets, and computers for real cheap you can't go wrong. Keep the truck around until you have the motor running in the Jeep, your going to end up needing O2 sensors, harnesses, and small parts you never knew existed.

If your going to do it, make sure it's worth your while. Don't put a 350 in unless your going to have 300+ hp, don't forget the added weight of a 350 over a 4.0 If you can find a used 4.0 out of another jeep you can buy that cheap and still drive your Jeep while your doing the stroker build on the new motor, then if you have problems down the road you will still have your original motor as a backup.

Either way, your adding more power to a drivetrain, your going to need to beef everything up, axles, U joints, brakes, you name it.

If you build the stroker with lower compression pistons you can always throw a supercharger on it later. Then you have a 4.6L supercharged stroked 4.0

If you are looking to improve you MPG on 33's, have you considered re-gearing to 4.56? It's a lot cheaper than a crate motor or stroking the 4.0L. Out the door, your're looking at approx. $1200.
