Re: Triumph 6 cylinder into 1500
doesn't sound like anyone has done this before. I would think space is going to be the problem, a lot more space in a spitfire to fit the 6. If you can get it work, it would be an interesting project.
Not sure how the weight of the 6 cyl engine goes, it felt pretty heavy when I shifted one out of a TR6! You would not want any more weight on the front wheels.
