| By placing a cam phasing system on the camshaft, a pushrod engine can be tuned to take much higher levels of exhaust gas recirculation. |
| The F400 uses a pushrod design and all the wishbones are aerodynamically shaped. |
| Metallurgical testing of the pushrod showed that it met material specifications. |
| This is done by providing pushrod length adjustment or by the use of hydraulic lifters. |
| The outer housing is guided in the cylinder head between the camshaft and pushrod. |
| A new cylinder head design employs the transfer arm and pushrod to locate the exhaust valve across the head from the dual intake valves. |
