[Spit] Ideal PRM for cruise

[Paul-Ernest Lévesque]

Hello I am driving my Spitfire MK3 for the first time, and I have the 1296cc 
and no overdrive and was wandering what should be the ideal RPM for cruise. I 
remark that the engine was turning 3700 RPM at 90 Km, that seem to much for me, 
but I am no expert
Have a nice day
Paul-Ernest
