| -4- free from vibration on the pick-up as the Chrysler. The 90° engines appeared smoother when accelerating than the Lincoln, but the latter was clearly running with a higher compression ratio and higher M.E.P. than the other two which were hopelessly woolly. They all showed up very well on the over-run. One would say that no critical speed would ever be reached with a normal car power range on the Lincoln if a heavy crank was used. We did not appear to approach it on the existing car. The 2" dia. pins and journals looked very small compared with modern practice. The Lincoln pistons however, seemed as light as anything we have seen. As the Lincoln is a reasonably good motor car we suggest that if it is desired to study the characteristics of this type of power unit it would be the best car to buy, unless a 90° engine is essential. We do not think that the Cadillac and La{L. A. Archer} Salle have been developed far enough to be of any use to us. An engine stripped after 30,000 miles appeared to be in excellent condition. We understand the purchase prices would be :- (1) Second hand four seater frabric saloon we tried after 15,000 mls...£1150 (2) New coach built car of the same type but this years model (now obsolete)...................£1150 (3) Replica of (1) but having rubber engine mounting and various other new modifications............£1300 (4) New coach built car as (3).........£1500 Net trade price Hs{Lord Ernest Hives - Chair}/Wm | ||
