Buick 225ci 90' V6-Power Potential????

I have a 1967 Jeepster Commando with a Buick 225 V6 Odd Fire. She appears to be a good runner, so far. A dose of liquid mechanic in the tank and oil helped her fire up. After 10 minutes of sputtering and smoking she smoothed out and ran easy.

What I want to know is this, what power upgrades are available for the 225? What is the potential output of this little engine and what are its limits? From what I am able to gather it is Buicks answer to the Dodge slant 6. It seems to be the indestructo motor. I love the sound of the loping engine but I'd love to pump some juice into her. Ideas?

There are quite a few upgrades still out there. The thing to remember is the 225 oddfire is an inherently unbalanced motor. In order to smooth it out, Buick used a much heavier flywheel. This gives it an incredable amount of torque, but limits acceleration. The engine can be built to compensate(Smokey Unick and Ken Bell were building race versions of this engine in the late 60's and early 70's). Places to look for performance parts...Ken bell,Offenhouser, Also do a serch under Buick V6. HP books printed a "how to build your Buick V6" book that was VERY informative. A good place to take your questions is to "early Cj5.com". They specialize in the Buick oddfire.
