Dyno Test: 464 CID Buick with Edelbrock heads on E85

Sunday, October 18th, 2009

The purpose behind this engine was to build a max effort street strip Buick 455 combo, using the new Edelbrock heads. The heads are fully ported and will be available from Competition Components. The car is regularly street driven, weighs 3900+ lbs and is cruised regularly, so race fuel was not an option.

Buildup:

  • Stock 455 Buick Block (+.038)
  • Finishline Halo Girdle
  • Stock 455 Buick Crank
  • 4340 Pontiac I Beam rods (modified to fit Buick journal)
  • Custom CP Pistons
  • ARP Main Studs
  • ARP Head Studs
  • Edelbrock 455 Performer Heads (Fully Ported)
  • Comp Pro Magnum Roller Rockers (1.6)
  • Custom Mechanical Cam (260 @ .050, .600 net lift)
  • Beehive Springs
  • Titanium Retainers
  • Cometic Head Gaskets
  • SCE gaskets for the rest
  • All Block Work by Finishline Motorsports   (Thanks Bobb and Geof!)
  • Romac Balancer
  • JW Flexplate
  • Proform 455 Buick Timing Cover
  • 4500 Carb (Modified for E85 use)
  • E85 purchased at local Meijer gas station for $2.22/gallon
 
Results:  703 HP at 6000 RPM – 653 @ 5200 RPM. 600+ lb/ft of torque from 4200-6000 RPM.
 
These heads are available through a group purchase in feb 2011. Details
