"Both sets of headers have 3-inch collectors, and we've chosen MagnaFlow mufflers with 3-inch-diameter pipe in and out for the Challenge." Indy has also decided on some other parts calls: "The balancer is from ATI. It's a two-ring design with an aluminum shell. We'll use our own Indy Cylinder Head sheetmetal valve covers, Fel-Pro head gaskets, and all MSD ignition parts (7-AL2 box, PN 8251 HVC coil, PN 8534 billet distributor, and MSD Super Conductor wires)." Okay, competitors--you've been warned, and you've had a chance to peek at "Parkhurst's Pick" to win this deal. Opposing viewpoints are not only welcomed but are encouraged. Who do you think will win, and why? We'll be waiting to hear from you. We'll see you next month with coverage of another Engine Masters Challenge entry!
