Work is underway on the Summit Racing/Factory Five Racing Mk4–both at Summit Racing Equipment and SKJ Customs.

The crew at SKJ Customs in St. George, UT is hard at work assembling the actual Mk4, and the folks at Summit Racing continue to put the final assembly on its new Mk4 Pro Pack combos, which will allow anyone to duplicate the build.

Check out our original Factory Five Mk4 post for more details, look for the Pro Pack part numbers to be shared via OnAllCylinders soon, and view the in-progress “spy photos” below.

The 427 cubic inch 351W engine is just about finished. Based on a Ford Racing 427 short block assembly, the engine features a bunch of Trick Flow parts including Twisted Wedge 185 cylinder heads, a Track Max camshaft, roller rockers, and pushrods. Other parts include a 770 cfm Holley Street Avenger carburetor on a Summit Racing Stage 2 intake manifold, MSD ignition, and other bits from Aeromotive, Milodon, Edlebrock, and March.
