If a standard crank (and a 3 bearing will be) a pity to stress, but my RP with standard valve springs bounced at over 40 mph in 3rd, or equivalent. You can work out the equivalnts from the ratio of the gear ratios. In the gears the car should accelerate continuously. It is difficult to find a really flat road with no wind and degree of warm up, temp, engine oil, makes a difference. Most cars are now oversize which also raise cr; the later slightly rounded car should certainly exceed a true 50 mph. (I think RRs car above is not pure RP engine) 30 in 3rd, a prudent limit, same revs as 50 in top.
