With a touch of epoxy and a little work with a grinder, Trovato matched up an Edelbrock Victor intake to the heads. Chevy and Ford guys were visibly jealous of the long sweeping runners and four corner watering the intake featured. Long runners build torque down low, and torque is the name of the game in Engine Masters. Taking advantage of a loophole that none of the other competitors did, Bill used pre-drilled and tapped holes in the intake water passages to bring hot water from the rear of the engine to the front, reducing hot spots and increasing power. Bill's on-hand CNC genius, Steve Gerrard, whipped up a tapered carb spacer that was sandwiched between the Vic intake and a Barry Grant carb.

Once the BTR guys had the mechanicals assembled, Bill used an MSD 7531 programmable ignition box as his baton to conduct the movements. The unit has the advantage of allowing various custom ignition curves to be instantly installed based on what the engine wants. In the end though, Bill found just as much power with the timing locked, so that was how he ran it. For the contest, Shell V-Power 91-octane fuel would be lit off, and make the transition through the chamber and into a set of American Racing A-Body Cutlass headers, then blasted out the rear through a pair of Magnaflow mufflers.

With all the players in place and the stage set, the team from BTR Performance raised the curtain on this Engine Masters Top 10 performance. The depth and anger of the singing Olds made the ground shake. Cutlass owners would've thrown roses on the dyno room floor had they witnessed the performance, for Bill Trovato and his accompanists breathed life and song into a mass of inanimate objects. The opera was now complete. Encore!
