The pointsgiven by FP and Boiler up make perfect sense. But remember, we are talking about a car that doesn't make sense. The Crossie is already a narrow market that sorta fits to a genre of buyers that like weird stuff. The V/8conversion makes it weider.
As for resale, again guys who want this, would seldom consider resale as part ofthe equation. There aren'tmany who will throw that kinda money at a few years of street fun.
Yet your end product would be more sensible than the original factory NA with the V6.
I'm sure the V/8 is where the Crossie model mighthave gone had Chrylse/Diamler continued.
So, I guess what I am saying is this is a fairly empty rabbit hole. I would advise you chase it for fun, not profit, as well.
BTW s a stick guy, I have a great interest but no funds. I am sure I am not alone there.
