Mog 615 .... Thanks for that ..... Turner was a talented engine designer (he also did the Speed Twin and Bonneville motorcycle engines for Triumph) .... I have heard that there are alternative designs of sump pan that can make the installation easier ..... would be good to see how the engine could be fitted with modern solutions for the steering column or using a wider +8 chassis.... not surprised it struggled on the track .... with the engine being slightly portly the last thing you need is it high up or uncentred. Still an intriguing 'what if' smile
