Choice of cylinder heads was definitely where the Lofgren team gained an advantage. By utilizing a set of cracked, factory '68 casting heads (that a customer refused to repair for his engine), costs were kept down, while substantial power was provided. The factory head is no slouch, and Chuck realized with some porting and proper valvetrain selection, this head would easily support the 485-inch motor at our 7,000-rpm limit. Port work was performed in-house, and Mopar Performance rockers, shafts, and stands were utilized to actuate the valves. Competition Cams provided the springs (PN 929), along with their valve locks and titanium retainers. Keeping in mind the budget factor of the contest, Chuck went with Mopar Performance 1.94-inch exhaust valves, but decided to show off another trick when it came to intake valve selection. Chuck claims to have gained a substantial amount of flow on the intake side by using custom Ferrea intake valves. These valves are a nailhead design, without the flow restricting material under the valve face that is found in the more conventional tulip-shape counterparts. Atop the heads, the Lofgren team chose Indy's 426-3 single-plane intake, which was match ported to the cylinder heads. A 1090-cfm Barry Grant King Demon took care of the fuel metering and performed flawlessly during the dyno pulls.
In addition to bringing a potent Hemi to our challenge, the Lofgren team impressed us with their professionalism. These guys were a fine-tuned machine making well thought out tuning decisions before applying them in the dyno cell. They were also the only team to bring a weather station and to run an air cleaner base on their engine, noticing the turbulence the dyno cells fans created. what more can we say, except congratulations.
