Love your build by the way!!

Thanks,

Thanks!

Propane engines are good ones to get as they are CLEAN! If you ever rip it down the valves and pistons will look like brand new. If the engine came out of a Schwann’s truck all you need is a gasoline fuel rail and injectors and you’re ready for gasoline action. On the other hand, if this was a gen set or well pump engine it could need an entire intake. I’d find out what the engine came out of before I jumped on it.

As far as the harness goes, I am not in favor of reworking original harnesses. They just are not worth the hassle. The best money you can put towards one of these swaps is starting with a new, clean stand alone harness from Howell or one of the many other vendors that make harnesses.

This thread should help you along…
