FWIW... I love Formals 74-78... factory low compression 440's in preparation for unleaded fuels and emissions devices. Big, heavy, beautiful, luxurious automobiles at the end of such a thing even existing on a showroom floor.
If I must be classified... C-body guy it is. Changing the carburetor or even a tiny cam/compression upgrade is no biggie. A slightly less restrictive exhaust with a low rumble is always nice, but I don't want to wake the neighbors and I don't need to hear it drone driving what was the epitome of style and luxury in it's day.
I dare you to compare the ride of a nice Formal to anything else... it is that good. Yes I admit there are comparable cruisers and lots with better power and speed/handling... but if that was what I wanted an SL55AMG would have fit into the garage easier and I don't think my investment would be that far off at this point.
Hell, I might even still call myself a Mopar guy if I bought it (they were still the same company for a minute back then)
. I don't personally relate to a lot of the stuff I see others do, but I usually don't feel bad about it if the car is preserved or easily reversed. I do somewhat hold with "it's your car"... but I would advise against radical modifications.
I like "classic" Mopars in general... I see some stuff that I don't love, some that I do. I still think that cherry original should do without disc brakes and that driver car is ok with having them (if done well). Minor internal engine mods would be very hard to detect and may pay off big in the feel of the car... too radical and you've possibly ruined it.
Thank you for asking my opinions on this. I don't know how you will receive my explanation of myself. Your car is yours, I hope it becomes what you want it to be. The one true sin IMO is to get so deep in that you can't get it together and enjoy it or destroy it so that no one else can ever love it.
