Thanks for all your input, guys. I appreciate it, and pretty much agree with all of it. This ZZ4 may end up being wrapped and stored until I find something else to install it in or get tired of looking at it and pay somebody to get rid of it

It's in the car now so for a short time longer I can demo it running, take it for a drive, measure compression and leakdown, etc. and that's why I hope to find a local buyer. I have a couple live inquiries but I'm not counting my chickens yet. But the replacement displacement will be here soon and then it'll be removed.
