Lets build a CHEAP(!!!!!!!) bracket motor!

So all those guys that say in other threads (some may be on this thread as well)

"no substitute for displacement"

...might be wrong?

Not necessarily. Here’s the thing. A 360 vs a 340 build with the same exact equipment, the 360 will make peak HP at an earlier rpm. Conversely, the 340 will make more top end HP at a higher rpm and hold on to that power longer where as the longer stroke engine starts to fall off.

As I stated above, you can ether rev the heck out of it in a short stroke engine to provide more working cycles per second or use a longer stroke engine to provide more torque to have the engine pull the car harder with more torque.

In order for the longer stroke engine to be more competitive, you have to start playing with gearing (trans and rear end) converter and tire size to maximize the power plants output for the 1/4 mile. This will show differently between the two cars when the engines are done the same way other than there actual displacement.

Bigger is better but it has to be utilized differently when bigger is in the stroke.
