Hi list! On every 'list' and in every club there is this dichotomy of opinions on whether certain mods are 'upgrades' or the'butchering' of a period production historical vehicle, which certainly our Imperials are. Be that as it may, Jay Leno's 55 Buick is certainly not stock with Vetter front 7 rear subframes and the 650hp crate engine. It is a beautiful car but not stock. The body & interior are 'period'- looks stock. As a Jaguar Concours Judge, I can appreciate both approaches, but the Jensen Community is always seeking 'improvemnets' for these fine Road Touring vehicles-the British 'equivalent' of our Imperials with their Chrysler drivetrains and mass so simlar to Imperials, not to mention Rolls Royce crafted interiors.. Laurence and I intend to really drive our Imperial, using it as it was intended, as a fine distance cruiser. Our first adventure,'collecting it' up will be this weekend! As for the Safety issue of Park in a GM tranny swap in a 57 (59?) Imperial, all of the early Jensen Interceptors used Chrysler 383/727 Torqueflites as STOCK from the 1960's- thru 1972 when 440's were used with the 727 thru the 1976 end of production. My Interceptor has a console mounted Shifter with a park position. Since the basic Torqueflite in 50's/60's Imperials is probably (help me out here) the same gear ratios as the later units with the park- why not consider at least a later Chrysler Torqueflite mod? They are the most bulletproof reliable tranny ever made!! Thius is where Chrysler excelled, even in the 50's and 60's, when body quality was 'an issue'. Chrysler had Drivetrain Engineering reliablity. I'm sure a 2ndary cable for the park position could be engineered, keeping the unique pushbuttons functional. On the other hand, I know that modern Land Rovers STILL use a drum parking brake on the drivetrain, so the Imperial legacy of Emergency /parking brakes is NOT DEFUNCT! As collector car owners surely keeping that brake properly adjusted for safety should not be an insurmountable maintenance item. It is my first issue on the '56 Dodge (enjoyable 'Magic Touch' pushbutton Drive thank you). Now since the drivers door key lock doesn't work, I often wonder about if 'someone' played with the brake-with the car on an incline. So I make sure I don't park it on an incline... Also, I use Marine Chrome polish on my Vintage Cars. The Marine formula (available in Marine stores everywhere) contains a good cleaner that gets those rust pits AND some petro oil film, that provides more protection from the elements-especially those tint pits. In fact most of those tiny pitscan't even be seen until your only 2" away For what its worth. My 2c plain....
