mark2bw.gif (7383 bytes) The ancestors of the XJ Sedan, these classics suffer from many of the same motor and transmission woes of its descendants.  The Mark came in several variations, including the Mark I, II, IX, X, 420 and S-types.
GM V6 Conversion GM power for a Jaguar classic, this conversion places a Chevrolet 90 V6 in your Jaguar Mark I or II Sedan. The S-types and 420 (not 420G) also benefit from this V6 conversion.   The required motor is a 90 Chevy V6 (200-229-262) with the distributor in the rear – beware, not all Chevy V6s with rear distributors are 90! Suitable transmissions include the GM 4 or 5-speed manual, T350 automatic or T700 overdrive transmission. The kit is for left hand drive cars only.  The mounts in this kit will not work with a V8. We reviewed V8 motors for this conversion and do not recommended them due to the small engine compartment and limited radiator area.
Mark Quarterbreed Stuck in 3rd gear with the old Borg Warner DG (Detroit Gear)?  Overdrive into the 21st century with a T700 overdrive behind your 6-cyl motor.  This is the latest of our retrofits and the best one you can choose if you want to keep your 6-cylinder.  A modern transmission with overdrive will amaze you.
Mark Parts We carry a limited range of spares for your Mark - generally any parts that are common with the the later XJ Sedans (brakes and suspension mostly).  We definitely don't have any body, trim or interior parts for the Mark. Check out our parts and products pages.
