Chad shows that you can add new rockers on the cheap by simply clearancing the baffles inside the stock valve covers. Chad wasn't sure where to clearance them, so Rick showed him an old set of valve covers he clearanced back in the day.
Of course, you can't add more airflow without adding some fuel to balance out the equation. Rick selected 31-lb/hr injectors to keep with the fuel demand at high rpm. At this power level, the stock rails aren't a problem, so you can hold off on those trick billet rails until you are ready to try out for King of the Street.
After cleaning out all the shavings, Chad drops the Professional Products upper into place. If you wanted to add more power at the top of the tach, you could select a larger, more aggressive intake-but it would be tough to do it for less than $400.
If you are going to rev to the moon, it helps to have an SFI-spec damper holding down the bottom end. This unit, as well as all the gear from Professional Products, does its job for an affordable price. The damper requires a spacer to adapt it to the 5.0 crank pulley.
Rick Anderson can't help but put a PMS on every car he gets near. While you could use a chip to add tuning and raise the rev limiter, Rick likes the flexibility offered by the PMS, as you can infinitely adjust your tune-up to reflect your latest combination without paying for a new tune. In addition to moving up the limiter, Rick took out some fuel and added timing throughout the rpm range.
To compensate for the larger FRPP 31-lb/hr injectors, Rick adjusted the injector flow rate in the software and downloaded the new settings to the load tuner to achieve a good, consistent air/fuel ratio for the PMS to work from.
Here's the finished product. Only having the Professional Products intake and AFM Power Pipe, this engine looks fairly stock. Our new combination gave up a little power and torque down low, but made up for it with triple-digit gains at the top of the tach. It certainly doesn't look as if it's cranking out 320 or more horsepower to the rear tires. The guy in the next lane would never suspect it.
