Oh great mighty one. I need to ask your sure fire opinion. I am driving an 89 Honda Wagon, stock manual transmission. I have a trailer hitch attached. I need to put in a new engine. My choices are a Z1, HF transmission with the lean burn controller, or a vtec engine with an HF transmission, or just a vtec engine and controller.

My question is power trade off's vs. mileage. From your conversion, it appears the lean burn/HF route has some substantial mileage potential. In your opinion, how is the low speed pulling power? If I were pulling a 4*6 trailer, up a steep grade, how would it fare?

Just an aside, I admire your willingness to try things out, just to see, what if.
