Tryin to make some ponies.

What would you do??? I have a 90 yj with the 4.2, mc2150 an the GM dizzy. Trying to get the best bang for the buck. Should I do the 4.0 head swap? Iv heard its awesome and that its not worth it. Get a mild cam and new timing chain or a 4.0cam? Both? I like the carb setup. Fuel injection might get more pricey than i wanna get, an what all do i need to do it? What do ya think?

Lots of info in the forums on this..... Do the head swap. It is good for 40-50hp which equates to best bang for your buck. You can also go with a more agressive cam and replace your timing set while you are in there.
A few FACTS:
Rectangle headlights ARE kinda cool.
YJ does NOT stand for "Yuppie Jeep".
Jeeps should only have TWO doors.
You should ALWAYS wave at other JEEP drivers.
