Thanks for the info. But, I can't make myself go forward with the whole new fangled engine idea. I hate computers, wires, and all the associated sensors and gadgets. I'm ordering a new L31.

I had to step back and think why I like the old stuff...it's simple. I ran the hardest trails in the US in a stretched wheelbase FJ40, from sea level to 12,000 ft with a simple SBC, HEI and quadrajet. Not the best mileage, not the best power over 8000 ft, but completely and totally reliable. I'm going back to that with a much better set of heads and a roller cam.
