Well, the engines are in a pair of New Idea combines, so I think governors come standard. The weight doesn't bother me much, as it would power a backhoe: the more, the merrier. The parts is really my main problem, though some forums have stated that Autozone carries parts for these. The truck idea only comes on the tail of my Viking, which will have an OD installed, by way of shifting the engine forward. I can't do that with the Apache, unless I get a shorter block. What size engine would you recommend for a 1 ton truck? I expect to carry lots of tools, but pull a trailer irregularly.
