Check out the accompanying photos and dyno numbers. Moly rings boast superior seating time which guarantees a quick break in for the customer. Toward the end of 1969 engineers dyno tested the DOHC W43, built with a very racy12.2:1 compression ratio, and recorded a very flat (and fat) torque curve. To start, John made sure all the critical thicknesses of the block were stout enough to handle extreme conditions, regardless of bore or stroke used. % It will run forever too. endobj This allowed timing to vary no more than 0.6250 degrees from the ideal. When you think of performance cars, Oldsmobile is not the first thing that pops into your mind. Chrysler had been playing cat and mouse with NASCAR for a number of years regarding the legality of the Hemi engine, which had as of yet not actually been delivered to a paying customer in a passenger car. Output ranged from 295 to 394 horsepower. No Core charge, Sold Outright So when Oldsmobile engineers began development of a super-high performance V8, it was only logical that it too would receive the W treatment, in this case W43. The engine is a torque monster, though, and if you build it to compliment its virtues, you'll have some kind of fun- just be sure you're on friendly terms w . With our more advanced engine setups we use the roller rocker to further decrease valve friction. The oiling system will incorporate a new Melling hi-volume oil pump with extended bolt on pick up to properly fit the 7 quart Moroso deep oil pan we will be using.

Development began in 1968 for a 1972 debut, but GMs decision to lower compression for all its motors for the 1971 model year due to emissions concerns ensured that the W43 would not see fruition. Edelbrock part #2058 Performer RPM Top End Kit is designed for 1965-76 Big-Block Oldsmobile 400-500 c.i.d. With their 4.250 or 4.500-inch billet cranks and 4.40-inch pistons on the shelf, you can easily get between 517- 548 cubic inches out of their block. Why were they burgeoning? Heads show semi-hemi combustion chamber with central spark. This was done to solve the problem of excessive wear on the rockers based on the angle of the pushrods. Home . To eek out more HP you can go with higher compression, which will prevent pump gas usage (highest stock 455 comp. And your definition of streetable would be? To get great performance out of any engine, all of the components must work together. stream Edelbrock techs are a phone call away to answer questions or help place orders. While it's important that other parts play a major role in producing power the heads are key. OW43 James Jordan has been a writer and photographer since 1980. Most testing was done with a ratio of 10.2:1 on 104 octane fuel. AIRFLOW TESTING Holley Sniper electronic Fuel injection add $1,975.00 As hydraulic camshafts, these are self-adjusting to eliminate valvetrain noise. Oldsmobile's version was part of the Rocket series of V-8 engines that powered its cars.

We use performance cylinder heads with 2.02/1.60 stainless valves, bronze guides, multi-angle valve job, new valve springs, retainers, locks & seals, screw in studs and guide plates, are all used for maximum horsepower. The bottom of the cylinders come clearanced from Rocket Racing for a 4.5-inch stroke with an aluminum connecting rod. Though rated at 430hp gross, the ZL-1 made 376 hp in its net configuration, not inconsistent with the output Chrysler was pulling from the Hemi. Let the HP fall where ever it wants to- the engine's forte is torque, not HP. Latter versions saved 75 lbs. One version of the engine featured camshafts driven off the front of the engine, another design had the cams driven by gears off the back of the engine.

At Eddies we found through all our years of building engines that the Melling high volume oil pump, pickup, and drive rod setup work best to ensure proper lubrication to engine. The chamber required no more than 29-30 degrees of spark advance. W43 By 1966 Chrysler had no choice and offered the Hemi in a number of different models, and not just performance cars. Forgedtrue developed 12.2:1 pistons for the DOHC. ), he set us up with all the parts necessary to keep the motor from seizing. So really, thats our standard for use in a years time. CGI is supposedly 75-percent stronger, given all the same thicknesses and design specs as agrey iron counterpart. With the redesigned priority-main oiling system in the block, redesigned Rocket Racing solid-roller lifters need to be used. Huge torque and power wth very little tweaking. Since the previous owner lunched it at one time (have receipts for reconditioned rods and a welded crank), my guess is that the crank is just toast and the rods probably aren't far behind.

In fact, Art Pollard drove the Plymouth-Westlake engine to victory at the 200-mile Indy car race at Dover, Delaware on August 24, 1969. Recall that the engineers of the 1960s could predict airflow through CFD (computational fluid dynamics), deliver fuel via a direct injection system that pulsed the output to assure the best possible mixture, computers that consistently monitored all engine functions that allowed maximum performance under the available condition, or any of the other tools and gizmos available to engines today. The cylinder wall thickness is at least 0.200-inch even with a 4.400-inch bore (the stock 455 bore is 4.125-inch, for comparison).
