If you're keeping the engine stock, I'd suggest just dropping in a junkyard motor and be done with it. It will be the cheapest and easiest route.

If you want to put a lot of money into a rebuild or new motor, I would upgrade to something with a little more power.

There are a few good engine builders here in N.E. Ohio. The guy who did my machining is really good, knowledgeable, and fair.

What city are you in?
