1978 Jaguar XJS XJ-S

Small Block Chevy Conversion / TH-350 Transmission
107,168 miles on car / ~ 7,168 miles on engine - mileage may go up from personal use.
I truly enjoy this car and torn on selling but have a strong desire to build-up a Mazda Miata -OR- Nissan 350Z for fun & track use. Driving this XJ-S I constantly get comments; often from folks loving the style and then when they hear the engine the common question is “What do you have in there?” It’s definitely not a ‘purist’ Jaguar; however, the Chevy conversion offers much improved reliability and much cheaper parts replacement cost. Starts and runs strong; biggest issue is power-steering leak as mentioned below.

New Floor Mats (functional part of carpet)

Replaced wiper motor to a new XJS version (orig cable version was problematic)

John’s Cars conversion for the small-block engine.
Previous owner (2-owners ago) had the V12 replaced with a GM crate motor via a GM Mechanic in California – I replaced the crate engine with a built-up small-block I had pulled from my ’71 Camaro.
