As I've got this on the list to do I had a quick look.
The rear chassis will need to be notched, engine support bar to be modified, and the engine bay metalwork and rear valance reshaped to seal the engine properly.
Haven't had an in-depth investigation yet, so there may be gearbox coupling issues as well.
I'd certainly have a word with Ben Lewis before starting though.
Hasn't Spence done any engine raises at the Old Dub Shop?
