It’s not everyday you drive up on the street next to a modified Cobra, but we can assure you that you if happen upon this monster at a stoplight, you’d better think twice before passing it off as slow. With a subtle stock looking exterior, you’d never know there were 800 ponies at the edge of the driver’s right foot.
This was a complete overhaul project that started with a perfectly good low mileage ’03 Cobra. We swapped out the stock Cobra engine for a custom spec Shrader 323 ci 4v monster. This features our 800XX shortblock which is a Ford Racing Boss big bore block, and a stroker crankshaft from Kellogg to get 323 cubes. We topped it off with 4v “C” Heads (unported) and some Comp Cams to help move the airflow through this air-hungry engine. The 3.4L Whipple supercharger was setup to produce a mild 23 psi on pump gas for now although it is capable of much more on race fuel or E85. Other items that finish off this combo are a set of Kooks longtube headers, JBA cat-back exhaust, Metco 4# lower pulley, and a custom Fore Innovations return-style fuel system.
In addition to the engine, we had to make some big upgrades in the rear suspension to be able to get this power to the ground. We started with wider 10.5″ Cobra wheels and Nitto rubber, and then completely rebuilt the IRS with all new bushings, braces, and hardware from Steeda. We also welded in some subframe connectors for stability, swapped in a Steeda K-member, and used Steeda springs with new Koni shocks/struts all the way around.
