'67 Firebird - Getting It Done
|
The top end of the 455 contains Holley's 1050 Dominator with No. 82/82 jets, which mixes air with fuel delivered by an Aeromotive pump and regulator and sends it to a port-matched Victor intake. A set of 310-cfm KRE-ported E-heads with 2.11/1.77 Ferrea valves, Comp springs and 1.6:1 Scorpion roller rockers are also featured. The 72cc chambers aid in producing an 11:1 compression ratio. A complete MSD ignition system provides the spark at 36 degress total all in by 2,000 rpm. Powerhouse Automotive, of Girard, Pennsylvania, installed the exhaust system featuring a set of Dawson headers, a 3-inch x-type pipe and twin mufflers to dispense with the combustion remains. If that doesn't make enough power, there's always the NOS Pro Fogger Nitrous system. View Related Article
