NEW DIAMOND FORGINGS FOR ALL 454-502 CHEVROLET ENGINES

The Chevrolet 454 and GM Performance Parts 502 cubic inch engines are mainstays of the street machine, drag race, dirt track, marine, street rodder aftermarket.

With the original 454 and 502 forgings no longer available, Diamond has not only introduced replacement pistons in a variety of bore sizes for both engines but also increased the compression ratios from the original 8.75:1.

Developed from 4032 alloy, the top ring land on both forgings is 0.300 inch down from the piston deck. However, the ring packs differ; the 454 manages 5/64-inch widths for the top and second rings, and a 3/16-inch oil control ring. The 502 uses 1/16, 1/16, and a 3/16-inch oil control ring. The depth of the inlet valve pocket for the 454 is 0.270 inch and 0.280 inch for the 502. No pocket is necessary for exhaust valve clearance.

Piston pins are Trend premium 8620 chrome-moly (case-hardened alloy steel); H-13 and 9310 endurance alloy pins are optional.

THE NEW HURRICANE+PLUS INTAKE MANIFOLD FROM PROFESSIONAL PRODUCTS

The new Hurricane+Plus is a major refinement to the extremely popular Hurricane. The existing Hurricane has long been recognized as the best performing single plane manifold for SB Chevy’s with 23-degree heads. Now the Hurricane+Plus offers improvements that will produce from 12 to over 20 horsepower (depending on the exact engine combination) over the standard Hurricane.

According to Steve Hart, with Team Z Racing, a long time circle track racecar owner who has won many championships with the Hurricane, the switch to the Hurricane+Plus produced so much extra top end power he had to switch gear ratios. "Awesome, very responsive," wrote Steve, "send two more Hurricane+Plus manifolds."

Various dyno tests on engines ranging from 350 to 400-CID have shown anywhere from 7, to as much as 20 more horsepower, over the standard Hurricane on 23-degree head engines. Hurricane+Plus is available in satin finish and polished finish. Visit www.professional-products.com for more information.
