’66 Mustang Convertible

 

Owner Kristian Holmen.

 


First upgrade – season ’04-’05

 

The heart of a vintage restoration.  Prepared by Stig Hroar Marthinsen and dressed like a ’66 K-code 289.  A ’68 302 block and ’66 289 cylinder heads makes 10:1 High Compression SB Windsor.  Featuring Mallory Unilite electronic ignition, Edelbrock Performer Plus cam shaft and intake manifold, Comp Cams Magnum roller-tip rockers and Shelby type Tri-Y headers.  Topped with a Holley 4010 600CFM manual choke carburettor and a HiPo air cleaner this package delivers almost 250hp – a good 60+hp on top of the 302-2V it replaced.  An Autolite 4100 HiPo manual choke (modified to 480CFM spreadbore) restored by Pony Carburettors was due for a later installation, but was sold during second upgrade.

 

 

The floor looked like the car had rested directly on the ground for decades before receiving a shop-shine in Ohio in 1998 covering everything in body-repair and a layer of fresh paint.  Most metal below your ancles had to be replaced.

 

 

A mix of sand blasted remains and fresh metal work.

 

 

Engine bay is almost ready.

 

 

Almost everything from the ancles and down ............

 

 

 

 

 

Chassis is typically sanded a second time after painting in order to achieve a professional result and a smooth panel surface.

First upgrade round is complete.

 

 

Almost a K-code.

 

 

Second upgrade – season ’06-’07

 

 

Ford Racing stage3 (B303 camshaft) 302 roller cam engine with 40-anniversary Paxton centrifugical blower – a tribute to the ’66 Shelby GT350S.  Inside the pressure box is installed a Barry Grant Speed Demon 650 CFM carburettor w. mechanical secondaries – blueprinted and blower prepared by Craig Conley at Paradise Wheels inc.

 

In order to make the complete assembly fit some CNC milling had to be performed – courtesy of Lars Bech and Jan Rype.  The Ford GT40X cylinder heads require a high-rise intake manifold like Edelbrock RPM (in this case the Air-gap version).  The Paxton pressure box is designed for installation on a standard intake manifold and will not fit under the hood combined with anything taller than a medium-rise design.  Hence was the top of the manifold grinded 0.22”, the bottom of the box 0.08”, top of the box 0.12”, bottom of the lid 0.10” and the flange on the lid 0.20” – total of 0.51” plus the flange.  The Weiand Action Plus 8124 intake manifold is said to fit (0.39” lower than the RPM Air-gap), but require meticulous gasket work and the runners are restricted compared to a high-rise design.

 

 

Front suspension is MacPearson from Revelation Racing (RRS) with Phase1 disc brakes.
