Yeah, there is a possibility that a PRU (prop reduction unit) may end up being the only way to make the high-revving V8 work but to be honest with you, such a requirement would kill this project. A PRU would add more weight forward of the firewall where it's not wanted and PRUs generally have failure rates higher than their engines.
I DO appreciate the points that you brought up in your subsequent post. I already plan to go with the dual ignition option regardless whether I install a V8 or the as-designed Model A engine. The oiling system of either engine would also have to be altered for the reasons that you pointed out as well.
Thanks for your insights!
