Level explained, “The World of Outlaws always tell you that they need more power.

But there comes a point where the car set-up and the driver are more important.” 360 Sprint Engines One step below the top-gun 410s are the more-numerous 360 engines which use steel blocks and aluminum heads.

Although it might seem that there wouldn’t be much difference between the three sprint engine sizes, that would be an erroneous assumption.

Following are the hows and whys of these killer engines from the builders themselves.

Griffith points to the fact that the 410 non-wing cars actually need less raw torque.

“The winged cars need it because the wing has the cars locked down to the track.” Level pointed out that, “We work a lot on the low-end torque which has to be smooth in the powerband.” There is general agreement on the practical compression ratio limits for the all-aluminum 410 engines. Kistler explains, “I once had it up to about 18:1, but decided to back off to the lower figure.” All the builders agree that it’s possible to build up more power, but is it really needed?

In addition, there are a number of tracks that provide venues for them to race.

They include Attica, Fremont, Millstream, Waynesfield and Limaland dirt tracks, along with the paved Sandusky track.

410 Sprint Engines Of course, the 410 cid all-aluminum engines are called upon to provide the greatest power, sometimes approaching 900 hp.

The stress on these engines, when mounted in winged sprinters (on either dirt or pavement) is a huge drag.

Not too far to the south is Tony Stewart’s famous Eldora Speedway dirt track and the legendary paved Winchester (IN) Speedway.

Some of these tracks support weekly sprint series with cars using two of the three engine displacements.

“Speaking of the valve train problem, the great acceleration of the engine tends to make the valve train unstable causing failures.” The 410s in wing cars usually have to be torn down after a specified number of races, Dennis Level of Level Performance explains, “It’s not unusual to find a bent crank, burned bearings and often the need for new pistons and rods.
