I'm trying to get ready to order my QB8 Finishing kit. I do not have an engine choice finalized yet. The plan, is to put an FlyEFII system on it.
So when they get to the question of Horizontal vs. Vertical induction, I have a choice to make between an XIO-360-M1B (horizontal) or an XO-360-A1A (vertical).
Based on my limited knowledge, I will be removing anything fuel or ignition related, so Carb or Injectors, throttle body, magnetos, etc. from the engine. Since I haven't located a used engine, I might be buying new. If I strip it down like that, am I just removing all the differences between those two engines?
I saw a post here, (dummy me, didn't bookmark it) and cannot re-locate it, titled something like "The same engine", where it linked to an article explaining all of the internal differences between different engines. Because the only difference between the two listed above, is not just Carb vs. Fuel Injection. If anyone can point me to that, I'll owe you a beer.
My understanding is that vertical induction is much more prevalent that horizontal. I am NOT worried about getting every last HP out of the engine. But I would like to know about other details like a counter weighted cam shaft, roller lifters, etc. That might give an engine a better life span.
Because of my building situation, I am doing some of this a bit backwards. Once I hang the engine, it has to go to a hangar due to space, and that will run me $500/month, plus driving time (an hour if I want power in the hangar, and 10 minutes if I don't). I am hoping to do as much as possible before that happens. And I don't want an engine just setting here getting old as I finish the build. I would love to run all the controls and wiring through the firewall before hanging the engine, but given this is my first build, that may not be possible.
How would you guys get past this decision point? I feel like I am stuck.
