Restored 1956 Jaguar XK140 Coupe Swaps Chevy Power for a 1964 E-Type Six

A 1956 Jaguar XK140 fixed-head coupe that once carried a small-block Chevrolet V8 under its bonnet has been brought back to Jaguar power. The car’s engine bay is now home to a 3.8-liter twin-cam straight-six sourced from a 1964 E-Type, giving the vintage coupe a meaningful performance upgrade over its original specification.

The transformation was completed in 2023 as part of an extensive restoration, according to the classified listing. The seller notes that the Chevrolet engine was removed and the body brought back to a proper Jaguar-engined configuration, with the E-Type six installed in its place.

For collectors, the combination is an appealing one: classic XK140 styling and chassis with the larger, more powerful twin-cam six that Jaguar later used in the E-Type. Such restorations are relatively common in the classic Jaguar world, where period-correct powerplants can be scarce or expensive to rebuild.

No asking price or further mechanical details were included in the summary of the listing. Interested buyers can find the full classified on the Barn Finds marketplace, where the car is being offered following its 2023 restoration.
