Richard only took a few of the exotic engines to the Euro due to limited space in the van he jumped in with.
The engine on his table that was at the far right was the GT300LC, the same as what's in my GP.
Some of my ride back which shows it taking it easy (rarely going above 6k rpm) down the M6. Peak power is 8300 rpm.
