Sounds cool UT.
So 139 is in transit as we type ....
Engine sounds a good assembly, and I think you should get 320 to the ground. #42 was laying 337 to the ground and it was a thrill to drive. Maybe next time I'll get to go fast enough to need the brakes. Last time I was more concerned at keeping all the gears and spinning bits inside the box while keeping all the tyres on the track.
Those Miaita's made an interesting whine as they went by .....
