"Dick's 500HP 427 V8 Engine"
"GULDSTRAND SIGNATURE EDITION 500HP 427 V8 ENGINE ON SALE"
Dick Guldstrand announces his Signature Edition 427 V8 Now Available For Chevy V8
Cars and Trucks.
Hearkening back to the glory days of pavement melting big-block horsepower and torque, Corvette racing great Dick Guldstrand, Chairman of Guldstrand Motor Productions, LLC., says that the New Generation 500 horsepower 427 V8 from his Signature Edition Anniversary Corvette is now available for all Chevrolet V8 passenger cars built after 1997, and with a special adapter, back to 1955.
Using SEMA, the world's largest automotive aftermarket show as a backdrop, Guldstrand unveiled the powerplant saying: "For a major industry event like this, you need to make a powerful statement. We believe that by offering one of the great performance icons from Chevrolet's past, the 427 cubic inch V8, it is consistent with the fantastic array of power accessories on display at this show. Seeing all this great Chevrolet hardware in one place makes you appreciate what the brand has meant to American performance industry. In conceiving the Signature Edition 427," continued Guldstrand, "our goal was to connect to the engine's rich heritage with a thoroughly modern application. Using the 427 configuration based on the Gen III engine allows us to do exactly that."
The New Generation Signature Edition 427 is built by Katech, Inc., from unique specifications developed by Guldstrand. Among its many accomplishments, Katech also produces the engines for the Corvette C5-R race cars that won at LeMans in 2001 and 2002 as well as the American LeMans Series Championship in 2003.
Beginning with the LS1 5.7-liter V8 block that comes in the basic Z06 Corvette used for the Guldstrand Signature Edition car, Katech bores out the factory cylinder sleeves and installs sleeves of its own manufacture which result in a 4.12-inch bore and a 4.0-inch stroke. The stock LS1 has a bore/stroke of 3.898/3.622 inches. The entire block is remachined using billet steel for main caps and both head and main bearing studs. Katech pistons are inserted in the enlarged bores, and rings are file-fitted to exactly match the bore dimensions of each cylinder. Carillo rods connect the pistons to a 4340 forged crankshaft.
To maximize air flow through the stock Z06 cylinder heads, Katech ports and cc's the combustion chambers to emulate their Stage III cylinder heads. While the rocker arms and lifters remain factory stock, titaniam retainers and stainless steel valves are employed with an adjustable timing sprocket and a stronger high performance timing chain from the C5-R race car. The camshaft has a high performance profile with higher lift and longer duration, but remains totally streetable. The compression ratio is 10.8:1. Inlet air flows to the heads through a Katech ported throttle body.
All of this adds up to a 427 cubic inch engine producing 500 horsepower at 5,600 RPM and 520 ft-lbs. of torque at 4,700 RPM. Yet, it remains totally suited to everyday street
driving with its attendant use of air conditioning and long periods spent at idle speeds in heavy traffic.
"The beauty of our Signature 427-powered cars," Guldstrand said, "is that the engine virtually drops right into all 1997 and newer General Motor product vehicles that use this basic block; Corvettes, Camaros, Chevy pickups, Firebirds, what have you. Plus, our special adapter kit makes it fair game for an even wider range of GM drive train vehicles." Retail price for a complete ready-to-run Guldstrand Signature 427 is $19,950, plus shipping and core.
"Like the original big-block 427 engine, we wanted the Signature Edition 427 engine to deliver true high performance," says Guldstrand. "But it also had to have the civilized road manners expected by today's drivers.
"After driving Guldstrand Signature Edition 427 powered cars to Corvette events all over America this past summer," Guldstrand smiles, "I think we accomplished that."
