In the early 1970's Nascar went to 355 cubic inches ? Ross became the first Canadian driver to win a NASCAR Winston Cup Grand National race. The 335-series 351-ci engine introduced for 1970 quickly became known as the "Cleveland" for identification purposes because there was also the raiseddeck 289/302 engine displacing 351 ci known as the "Windsor" introduced a year earlier in 1969, which made things confusing for Ford dealer service technicians and shop mechanics everywhere. The Tunnel Port 302 cylinder heads feature 2.12" intake and 1.54" exhaust valves. Pearson lead entering the final lap, but pulled down to the low groove to allow Petty to pass. in. The shape of the spacer helps a car funnel more air smoothly into the manifold, increasing fuel performance, while ensuring airflow is still restricted. The Automobile Racing Club of America also enforced restrictor plates at their events at the two tracks. Isaac ran about half the races in 1971, winning four times. So that gives you an idea of how much aluminum is sitting on the floor when we are done.. FastestLaps.com 2023 Its a unique way to develop engines essentially eight one-cylinder engines that happen to share the same crankshaft but ECR has been able to make engines light and optimized for specific tracks quite successfully. by CamKing Wed Feb 27, 2013 3:51 pm, Post He held off a late rally by Cale Yarborough to win by only 67.15 points. A single four-barrel Holley carburetor delivers the engine's fuel. NASCAR used three different size plates in 1971, issuing more restrictive plates to teams running bigger engines. -Heavy-duty rear axle required to keep cars from flipping during the race. [47] The transition was not complete until 1974 and coincided with American manufacturers ending factory support of racing and the 1973 oil crisis. These performance enhancements that ECR creates is all part of the teams engine development philosophy, which is not to develop the engine as an 8-cylinder engine, but rather as eight one-cylinder engines. The cars are currently powered by EFI V8 engines, since 2012, after 62 years using carburetion as engine fuel feed with compacted graphite iron blocks and pushrod valvetrains actuating two-valves per cylinder, and are limited to a 358 cubic inch (5.9-liter) displacement. Intake (lb-ft/rpm) If you really must look at the statistics for all 102 events (and nine out of ten doctors are dead-set against it), you'll find them here.

The NASCAR version was much more powerful, as the NASCAR version had a 12.5:1 compression ratio, compared with the 10.25:1 ratio in the street version.

Even with behind-the-scenes friction, the 1970 NASCAR tour produced many great moments. The restrictions are in the interest of driver and fan safety because speeds higher than the 190mph range used for Daytona and Talladega risk cars turning over through sheer aerodynamic forces alone. The introduction of V-8s, made the two series' cars increasingly similar. The change occurred in the middle of the production year so some early Cobra Jet cars had 428's, later cars were 429's . The goal was to stay period correct, so I had the cam ground close to stuff advertised in old Hot Rod magazines and build it like a guy made a few trips to the local speed shop back in the day, Jason says. Check it out! 1994 was the final year that V6 engines were used in the Busch Series, as many short track series had abandoned six-cylinder engines.

These heads were fitted with sizable intake and exhaust valves (2.02" intake, 1.60" exhaust). By 1972, NASCAR phased in a rule to lower the maximum engine displacement from 429 cubic inches (7.0 liters) to its present 358 cubic inches (5.8 liters). in area at the intake manifold face. On large tracks such as New Hampshire Motor Speedway, the engines must have a restrictor plate between the carburetor and intake manifold, reducing engine power and car speed for safety reasons.

A 0.922-inch spacer will be used at all oval tracks 1.33 miles and above, which will decrease engine horsepower to about 550. The severity of crashes at higher speeds is also much greater, shown by telemetry readings of wrecks such as Elliott Sadler at Pocono Raceway and Michael McDowell at Texas Motor Speedway that were far higher than registered on restrictor-plate tracks. Following testing and input from drivers such as David Pearson, Bobby Isaac, and Bobby Allison, NASCAR mandated the use of a restrictor plate for the big-block seven-liter engines.
