Indianapolis, Ind., April 20--- What the future will see in pae- senger car design, the present may observe in the special speed pren tions now being prepared for the Sixteenth Annual International 500-mile race at the Indianapolis Motor Speedway on May 30,

It is on these models of to- morrow's stock cars that engineers are testing their advanced theories for the improvement of the auto- mobile of to-day To make this posible, the racers have to be bull with different parts and with more individual attention than' those built for daily use.

There is a difference in the

INDIAN- MOTORCYCLES shape of valves, the shape of the intake and exhaust ports, the motor heads and the manifolds. The metals are of different cant and differently heat treated and there is an experimental air of uncertainty in the race car against the practiced efficiency of the stock cur.

The stock car is a problem solved; the race car a problem of future transportation being solved.

Big Race Tests Ideas.. "We don't want to learn any thing about the ear of to-day." anys Earl Cooper, veteran driver for the Marmon Specials in the coming race. "We know about it. It is the car of to-morrow in which we are interested,

"We have Home engineering ideas we believe are sound. So we are incorporating them in the race cars. If the cars go through the gruelling 600-mile contest, which is the equivalent to a year's ordinary driving, the ideas are all right. If they don't we will learn why."
