Do what ever blows your skirt up...LOL
don't worry about what others think, especially the purists, I certainly won't & don't
Please don't take what I say as a insult, it's not meant to be at all...
If it's done with quality parts,
I doubt it will be worth much less "if any" {possibly more $$$}
mainly because a 318ci base or lessor model engine equipped car...
IMO IT isn't really what most collectors, that are going to pay a premium price for,
or are really looking for anyway, such a small market clientele, to appease...
IF it's done right, with quality workmanship & quality parts,
then the slightly modified, even era correct looking or even the resto-mods &
updated BB clones, can be worth more today, again that's IMO...
It's yours, build what you want, especially if it's not for resale...
"Build it how you want it, use what ever parts you want/need to, drive it like you stole it
& damn the rest, who cares what others think"
