Tony’s 512 Wedge On the Dyno

Bill Amsdill’s 10 Second Street Strip 73 Oldsmobile Cutlass

Tuesday, July 19th, 2011

Bill is a pretty typical Olds guy. He likes his cars to be fast and look good, but he also likes to be comfy when he takes his wife Cathy out cruisin’. Their 73 Cutlass does all of that and more. Bill picked up the current engine from a guy in Ohio that had difficulty keeping the combo running. Bill and the previous owned agreed on a price and Bill brought the engine to us in milk crates, which we freshened and tuned up.  It consists of a stock block with the Mondello bottom end girdle and matching oil pan. The crank is an Eagle 4.250 stroke cast unit, with their ESP H beam rods attached. The pistons are Probe pieces, with Total Seal conventional rings sealing them up. The heads are Edelbrock Performer RPMs that have been CNC Ported and had 2.19/1.68 Stainless valves in them. The valve springs are dual from PAC, and with lightweight tool steel retainers, Scorpion Roller Rockers, and a Jomar Stud Girdle.  The Cam is a street roller from Scott Brown at Competition Components with 268 @ .050 and .700 lift. The Intake is a port matched Edelbrock Victor, with a  Holley Dominator converted to run on E85.  A TCI Converter is plugged into the TH400, connected to a 4.10 gear.  Bill runs Warren Gear in Michigan, so you only get one guess as to where the 12 Bolt was assembled. The car is raced in the same trim as it is driven, full 3″ Exhaust to the bumper,  9″ Hoosier radial slicks. and weighs in at a portly 3985lbs. The car has run a best of 10.85, and has been in the 10.90’s regularly. With some more ironing out and testing, as well as a few smaller mods, we are looking to see Bill and Cathy’s Olds in the 10.70’s

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.
