Chrysler HEMI and WEDGE Engine Based Blocks

  • A356T5 Aluminium is superior to other alloys. It has proven to be easily repaired, and has a high thermal transfer rate which offers superior cooling to cast iron.
  • Low-pressure casting process produces a superior product. This allows for tighter tolerances and improved quality. No core shift maximizes casting stability.
  • Higher densification does not require HIP or other processes, as casting quality is already unmatched in market place.
  • Vital internal threads, both heads and mains, are machined to Class S3 spec. Both blind tapped w/ ball end studs which provides even load distribution. No other block has this feature.
  • Long service life, threads will not pull from block, a common issue with other block manufacturers.
  • Both external and internal ribbing with robust cam and main bearing bulkheads.
  • Only block strong enough to offer a 65mm Babbit or 60mm needle bearing option with a raised cam. KB offers massive material support for camshaft.

Keith Black (1926 – 1991)

The name Keith Black is synonymous with drag racing engines. He was so successful that his name, and even his initials, have become part of the racing language.

Born in Huntington Park, California, 1926, Keith Black lived and worked in the Golden State all of his life. From an early age, he was a hands-on kid: “I always liked to get involved with mechanical things. When I was about 14,I talked my mother into letting me take the old family car apart. I put rings and bearings in it, and when my dad came home, he about croaked when he saw his car al apart in the driveway, and his kid working on it.” His apprenticeship in the world of high performance included stints with Clay Smith, Art Sparks and Cliff Collins.

Black made his name, first in the world of boat racing in the mid- 1940s. He was a fast learner, setting a world record the second time out on the Salton Sea. “I raced boats for a bit myself, then someone said, “Come build an engine for me”,  and I built an engine (a flathead Ford) for him. And then somebody else would say, ‘Well, that ran good, so build me one,’ and someone else would want one, and so on. My engine business started in my backyard.

In 1959, he opened Keith Black Racing Engines. By 1961, his boat racing exploits included nearly 50 national and international records. As his reputation grew, drag racers began to solicit his expertise. Tommy Greer, a longtime friend, then approached Keith with the idea of running a car together. It took more than a little convincing, but the final result was the famed Greer-Black-Prudhomme Top Fueler. During the 1962 and 1963 seasons, it won over 250 eliminator rounds and lost fewer than 25! Prudhomme was succinct in his assessment of Black’s abilities: “It was unbelievable how smart Keith Black was.”

Part of what made Keith Black so smart was his ability to take advice from the right people. “I accept what people say, if they are the authorities on what they are taking about. If what they say makes logical sense, then why not buy?” This information exchange was very much a two-way street. Many racers can remember long phone conversations with Black, picking his brain for insights, which he readily shared. “We provide an ongoing service center for information,” he said of his organization. “There is no limit. We’ve always tried to take the attitude that, if the customer does well, then we do well, so anything we can do, that will enhance his capabilities to do better; ultimately we gain from.”

After stints with Roland Leong’s Hawaiian Top Fuel dragsters in the late 1960s and the Plymouth Barracuda Funny Car campaigned by “Big John” Mazmanian in the early 1970s, Black abandoned hands-on drag racing. He limited, if you can call it that, his activities to that of an engine manufacturer.

Keith Black’s development skills were not only known among racers, they were highly regarded by the Big Three as well. In 1965 Chrysler contracted with Black to develop their marine racing program. Keith loved this type of R&D work because of the challenge it presented, and the fact that it made good business sense.

In 1971, Ed Donovan introduced the first aftermarket aluminum engine. Before long, a half-dozen engine building businesses were battling for the lion’s share of the aluminum aftermarket block/engine combo market. In less than a decade, Keith Black Racing Engines would come to dominate the market.

Virtually every top-name racer who has competed in Top Fuel or Funny Car has, at one time, used Keith Black equipment. His customers included legends “Big Daddy” Don Garlits, Don Prudhomme, Shirley Muldowney, Kenny Bernstein, Joe Amato, John Force and “T.V.” Tommy Ivo, to name a few.

Affectionately known as “Uncle Keith” to many friends in the drag racing community, his passing in 1991 to cancer was a sad day for all high-performance enthusiasts. The legend of Keith Black Racing is worldwide, and his name will live on, in the annals of motorsports forever.
