Adding a big block engine to a ponycar calls for certain well-known measures, as well as some that have to be taken on the fly. In addition to the monster subframe connectors, a six-point roll cage was added to keep the body straight under all conditions. Custom headers had to be made up and these were ceramic coated after verifying the desired fit and performance. The distributor was also re-curved for improved performance. That's how you did it in the old days ... none of this computerstuff need apply. A Holley Blue 280 lph fuel pump was needed to keep the carb bowls full and a Griffin four-core radiator was put into service. An MSD Ignition 6AL controller is used to keep the home fires burning and Auto Meter gauges in an A-pillar pod report continuously on critical functions.
Now, serious power needs equal measures to get that power where it's needed.A Ford C-6 automatic tranny does thejob here, feeding Ford's 4.10 rear axle gears mounted on a Ford limited slip differential,that is helped out by an SVO axle girdle.The final link in that chain is the ROH17 x 9-inch rims, covered with Fuzion rubber - 245/45R17 up front and in the 275/40R17 size out back. An Anthony Jones Engineering front K-member replaced the original, helping the Koni-based suspension keep thoseFuzions on the road.
During its time with Scott, the car has gone through some other changes. At one time,it had a 1050-cfm carb on it. In that trim, Scott ran the quarter mile in 11.9 seconds on street tires and with a leisurely launch.There are still a couple of issues to sort out with carbs and tuning, but once handled,Scott is confident that his reward will be breaking into the nines. Proving that this car's fit and finish arejust as good as its get up and go, Scott brouught home both the Best in Class and Best Mustang awards form last year's Fun Ford get-together in Commerce, GA. Not too bad for a fellow that may have grown up riding around in a Chevy Vega. Without a doubt, the Fox Mustang platform is among the most suitable for modifications. After all, show and go in the same package is never out of style.
