AFAIK the only differences between car and plane engines are that plane engines don't have as good bearings on the crankshaft as there's no sideways forces exerted on a plane crank and plane engines don't normally have big heatsink heads as they operate in a continual cooling flow of air
There may be other differences but other than those I don't know

plane motors dont produce near the power or rpm of car ones. you can expect a good 2 hp at 30,000 rpm and a top rpm of close to 50,000 out of your normal .25 truck engine.. as where a .25 plane motor might hit about .8 hp at 16,000 rpm wiht a top rpm of about 23,000 rpm.

plane motors also arent built to hand the constant throttle up and downs that car and truck motos do.. they wil get very hot very fast. stick wiht a motor thats built for the purpose you want.

I have found that a plane motor just doesn't hold up in a truck. I never had the power that I thought it would, and it was terrible to try to cool.
