I've been a member of the Classic Jaguar Assn. since 1963(#613). I own a 1948 Jaguar 3.5 Liter Saloon(630027) since 1961. At present, the car is waiting to be re-assembled after a body-off restoration by me and several friends over the years. Even the wire wheels have been re-wired. It has every option from the factory, including fitted luggage and Ace Rimbellishers and every original piece of paper from the dealer. In fact, Jaguar USA copied the greasing chart from me because they didn't have one. Hopefully, the car will be assembled for concours this year. I did modify the engine internally to modernize and improve it. It has steel con rods and the water-pump seal has been converted to the XK-120 type. It also has new 4-ring pistons and teflon valve seals(there were no valve seals at all). The crankshaft is balanced to 8000rpm. and the pistons and rods are exactly the same weight.
