This clean 1969 Chevrolet Corvette Roadster is currently powered by an anemic small block Chevy and shifted with a factory 4 speed manual transmission. The combo is cool, but the owner wants to add more zip to this machine so he elected to go with a GM Performance Parts LS3 crate engine with Holley EFI and a Tremec T56 6-speed manual. Follow along as the V8 Speed & Resto Shop crew complete this transformation and add some additional upgrades from Detroit Speed, Wilwood brakes, and YearOne wheels.

From Engine Builder Magazine

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.”

Edelbrock is excited to begin shipping the highly anticipated E-Force Supercharger system for the C7 Corvette Stingray. The all-new design increases the stock 6.2L LT1 (Gen 5) engine up to an impressive 624 flywheel horsepower and 600 ft-lbs. of torque.

This supercharger incorporates the Eaton® Gen VI 2300 Twin Vortices Series (TVS) rotor assembly, as well as an air to water twin intercooler system and dual core heat exchanger. Performance has been optimized through a unique runner design and an integrated bypass valve that helps reduce parasitic loss under light throttle, which improves gas mileage potential. All of this technology fits under the stock hood without modification to the hood, hood liner or cowl.
