For engine builders, and enthusiasts with ambitions in hot rod engine assembly, Jon Kaase has introduced the Boss Nine in a new kit form.
Among the kit’s more prominent components, Kaase includes his noted semi-hemi cylinder heads with accompanying pistons, pins and rings as well as pushrods, shaft-mounted rockers and induction system. Everything to complete the full assembly is supplied.
Though power production may vary from 500 to 1,000hp in naturally aspirated form and up to 1,500hp under forced induction, it is the engine’s evocative appearance and heritage that heightens its universal appeal. Predictably, options abound and powder-coated cast valve covers are available in silver, red and black. Indeed, in any color that can be indentified by a paint code. In addition fabricated sheet metal covers are offered in natural aluminum finish.
In performance the Boss Nine’s magic is ignited by increasing its stroke length from the original late-nineteen-sixties specification of 3.590in. “Those big-port heads,” contends Kaase, “don’t like stroke lengths shorter than 4in., and respond enthusiastically to 4.150in, 4.300in or 4.500in, all of which we use.”
Because the longer 4.500in stroke causes the piston to protrude from the cylinder at bottom dead center, Kaase recommends a Race block or a “79” block, which has a 0.250in longer cylinder wall. Produced from 1979 to the mid-‘90s these can be identified by the nomenclature D9 on the block’s external surface. “They’re robust,” declares Kaase, “and we have one at the shop. It is 0.030in over-bored with 2-bolt main bearing caps and has taken the abuses of fourteen years of dyno testing. It usually generates between 900 to 1,000hp and we’ve used it on all Boss Nine and P-51 tests—it’s still going strong.”
The Car Craft Summer Nationals is all about variety, and we took some time away from our display in the Pro Builders Shootout to grab some snap shots of cool cars and trucks at the event. Car Craft claimed over 6000 cars and 40,000 people attended the event, and we believe it!
There were many V8 Speed & Resto Shop customers and cars our crew had worked on at the 2014 Car Craft Street Machine Nationals in DuQuoin, IL over the past weekend. Shown is the House of Kolor TruBlue '66 Chevelle, a car that spent some time in our shop getting some mechanical maintenance, a new hood, and some other paint work. Overall, there were at least 6 cars in the show that we've helped restore or maintain. It was a fun event!
New Rocket Racing Wheels for the '69 Chevelle! The Hyper Shot finish should look sweet against the metallic black color of the car. We're running 17x7s in front and 17x8s in the rear, and the BFG tires offer a slight tire rake for an agressive look. Cool stuff.
More than three decades after taping a full-page ad ripped from a 1965 car magazine above his bunk on an Alaskan crab boat, Mark Hovander is touring the country this year with the same Ford Shelby GT350 Mustang pictured on that page.
Hovander and his crosstown friend John Atzbach are big fans of the first-generation Shelby Mustang, and between them they own two of the three original prototypes. As Mustang enthusiasts across the country and around the world celebrate 50 years of their favorite pony car, Hovander and Atzbach are bringing their cars to nine different events in 2014, including this weekend’s 40th annual Mid America Ford and Shelby Nationals in Tulsa, Oklahoma.
Hovander’s car bears Shelby serial number SFM5S003, while Atzbach owns SFM5R002. Those numbers identify the cars as two of the three original prototypes used by Shelby American to develop the road-going and racing versions of the GT350.
“In 1980, I went up to Alaska to work on a crab fishing boat to earn some money in order to buy a 1965 GT350,” said Hovander. “Since space was limited, we were only allowed one duffel bag. I was a huge Shelby Mustang fan, so in addition to my clothes, I brought an ad for the GT350 that I had ripped out of an old Shelby American magazine.
We perform lots of metal repairs on Muscle Cars, and today, fabricator Adam Schulte gives us a tour of a '67 Camaro RS he is working on in the shop. Tasks included installing Detroit Speed Mini Tubs, Classic Industries quarter panels and roof skin, and other sheet metal repairs. Contact the shop today to discuss your restoration project!
