Britishv8.org has published an article about a 1954 Austin-Healey owned by Martin Jansen with a Jaguar V8 swap. The car has a 5.3L Jaguar V12 engine which is balanced and blueprinted. No reason to keep it naturally aspirated so a Vortec V2 supercharger was added. The power is handled by a Tremec 3550 TKO 5 speed transmission and Ford 9″ differential. The suspension was kept pretty much stock except for minor modifications to help with the drive system. For more details please check the BritishV8 article.
