    PROTOTYPE ENGINES: OLDSMOBILE ‘ROCKET’ SCIENCE!

    These lightweight multi-carb, four-cam and even Hemi engines were being developed for future production engine research and, in some cases racing projects.

    PROTOTYPE ENGINES: OLDSMOBILE ‘ROCKET’ SCIENCE!PROTOTYPE ENGINES: OLDSMOBILE ‘ROCKET’ SCIENCE!Between 1969 and 1970, Oldsmobile Engineering was responsible for creating powerful ultra-efficient 350 to 455 cubic-inch V-8 engines rated up to 700 horsepower! Some were naturally aspirated and fitted with single Quadrajet four-barrel or Weber carburetors; others were fuel-injected and turbocharged. Most had aluminum blocks and heads. It was hard to imagine that these engines were anything other than veiled attempts at building pure racing engines, but they actually were. Oldsmobile engineering used these engines as prototypes for developing lighter, more fuel-efficient and “cleaner” production engines.

     Olds engineers were responsible for the radical OW-43, above, a racing-only, four-cam 455 tested with four Weber carburetors and fuel injection with three-inch ram stacks. The OW-43 was developed at the same time Chevrolet Engineering was working on the ZL1 for Corvette and Camaro applications and Can-Am racing. The OW-43 was tested in a Can-Am racecar, but never used in competition.

    Based on the same bore-stroke configuration of a production 455, the OW-43 had heads and block with steel cylinder liners cast from Reynolds 356-T-6 heat-treated aluminum. With a redline of just under 8,500 rpm, it produced 600 horsepower at 6,000 rpm with Webers and 700 horsepower at 6,800 rpm with Lucas direct-port fuel-injection. The DOHC prototype had Forged-True 12.20-to-1 pistons, Carillo billet steel rods and a forged steel crank. It weighed 50 pounds less than a production cast-iron 455.

    The mildest of the group was an all-aluminum 350 small-block, displacing 389 cubic inches and utilizing dual-throat Weber 48IDA carburetors, above, right. The alloy 389-inch engine ended up in a Cutlass that was driven to the C/Production record at the Bonneville Salt Flats in 1968. A friend and editor at Hot Rod, Lee Kelley, drove a factory-supplied Cutlass 169.133 mph to set the record. Apparently during impound, SCTA officials never detected that the engine was an all-aluminum prototype.The engine in Lee Kelley’s record-setter was a one-off, rated at close to 500 horsepower and built in Lansing by Dave Maurer, a special projects engineer. At Bonneville, the Cutlass was crewed by Maurer along with racing legends, Ak Miller, Jack Lufkin and Ed Iskenderian.

    PROTOTYPE ENGINES: OLDSMOBILE ‘ROCKET’ SCIENCE!One of the most interesting engines was the 455-inch W-43 Hemi. There were cast-iron and aluminum iterations with four-valve, Hemi-chamber heads. The W-43 engine was designed to be easily converted to chain or gear-driven overhead camshafts. Fitted with a single Quadrajet, it produced in excess of 500 horsepower at 6,500 rpm. The aluminum version weighed 75 pounds less than the then current production 455 engine. This engine found its way into Mule cars tested at the Milford Proving Ground.

    PROTOTYPE ENGINES: OLDSMOBILE ‘ROCKET’ SCIENCE!Oldsmobile engines displacing 389 to 455 cubic inches had powered Can-Am Series cars, like Bob McKee-built Cro-Sal racers in 1967. The highest output Can-Am Olds was an all-aluminum, single-cam 455 with injection and twin turbochargers. It generated 659 horsepower at 6,250 rpm and 554 pound-feet of torque at 6,200 rpm.

  • Win Free Insurance With Approved Used Triumphs in July

    Buying secondhand motorcycles is a lot of fun. But it can also be a bit stressful, which is why manufacturers have introduced approved, pre-owned schemes. It means you get a bit more peace of mind when you’re buying a bike previously ridden by someone else. And as a bonus, you can currently win free insurance with approved used Triumphs in July, 2018.

    Buy an approved pre-owned Triumph from the Adventure, Roadsters and Modern Classics before the end of the month and you’ll automatically be entered into a prize draw. And three winners picked at random will be offered Triumph Insurance for 12 months, up to a value of £500. And if you’ve already got cover sorted, the offer will be valid for two years.

    Win Free Insurance With Approved Used Triumphs - Like the 2016 Triumph Bonneville T120 and T120 Black

    You can buy from the Approved Pre-Owned Triumph stock either online or through participating dealers. And there’s a list of checks which are carried about before a motorcycle is available.

    All the Triumph motorcycles available as an approved used example will be under five years old from their first registration. And they’ll also have done no more than 25,000 miles.

    To be included in the stock list, the bikes will also have received any service required within 1,000 miles or 3 months. And they’ll undergo a multi-point inspection and any rectification work required. So you get the benefit of a vehicle history and mileage check, a certified vehicle quality check, and full service history. The checks include the frame, suspension, steering, final drive, wheels and tyres. And a full engine diagnosis, exhaust system examination and electrical inspection.

    Other benefits to the Approved Pre-Owned scheme include a one year MOT. Plus a one year unlimited mileage warranty, and a full year of Roadside Assistance just in case.

    As a final incentive, Triumph TriStar Finance is also offering a 7.9% APR deal on the Pre-Owned range until the 31st July, 2018 as well.

    Paul Lilly, general manager of Triumph Motorcycles UK and Ireland, commented: “With a comprehensive multi-point inspection and a quality & safety check by a qualified technician, we’re confident that each Approved Pre-owned motorcycle will perform like a factory fresh bike for its new owner for complete peace of mind.

    So full checks, a finance offer, and the chance to win free insurance with approved used Triumphs in July. Not a bad way to celebrate summer, really?
