It is applied to all types of chemical compounds, but most syntheses are of organic molecules. Pneumatic injection pumps, electric chemical injection pumps and solar metering injections pumps are used for, but not limited to, methanol injection, corrosion inhibitors, biocides, scavenger injection (H2S, Oxygen etc), asphaltine and other hydrocarbon treatment applications. The fine vertical bar treatment used in 1976 was replaced with five thick bars on each side. Most small rodents can be adequately socialized with at least five minutes of handling per day. Powerplant offerings for 1974 included the standard 400-cubic-inch V-8, which dropped five horsepower from the year before to 225. The 455 V-8, which held its 250 horses, and was again standard in the SJ. The 1975 model year saw some significant changes in emission control devices and a subsequent reduction in horsepower. While the horsepower rating would only rank as mediocre for the current crop of four-cylinders, the power level of the 301 was similar to other 5.0-liter V-8 engines of the period and had the advantage of being lighter in weight. Base price was reduced by $500 and the standard equipment level was lowered somewhat. The total for model-year 1975, a generally tough year industrywide, was 86,582 Grand Prixs, 64,581 of which were standard J models.

Anniversary models could be considered a good bet for future collectibility, as few are ever seen at car shows. The 200-horse, 455-cube four-barrel was now an option for all models. Next up the option ladder was the “5.7 liter” V-8 engine. The top GP engine option for 1977 was the “6.6-liter” V-8, which was standard in the SJ. The 455 V-8 with four-barrel carburetion was down to just 200 horsepower; it remained standard in the SJ. The 350 V-8 was the smallest engine ever offered in the Grand Prix up to that time. For those areas, the division substituted the Oldsmobile-designed 350. Since the Olds engines were cleaner running than the other GM V-8s, there was a great demand for them. The resulting shortage of Olds 350s meant that not even Oldsmobile had enough of them for its Cutlasses. ­Since even the best economy is unreliable, it’s a good idea to have a­ contingency plan. Already fairly rare when new, they are even more so today.

The overall effect made the front of the car more massive looking than before. Depending on the time and plant in which a car was built and the zone to which it was delivered, the buyer might receive a 350-cubic-inch Pontiac, Olds, or Chevy engine. Depending on the state to which a car was to be delivered, there might be a Pontiac-, Chevrolet-, or Oldsmobile-built V-8 under the hood, as there was a 49-state engine lineup and a California and high-altitude lineup. The 1975 engine lineup was as follows: The base engine was a four-barrel 400, now rated at a rather lethargic 185 horsepower, a loss of a full 40 horses. On the next page, find out how Pontiac updated the 1976 Grand Prix lineup. The taillamps were also updated slightly. The new styling effectively updated the look and significantly broke with tradition. The 1975 Grand Prix was essentially a carryover from 1974 in terms of styling changes. The 1974 model year saw little more than some minor cosmetic changes. Of course, if a more upscale version was desired, the SJ and LJ were still both available, each returned with similar levels of trim as in 1975. Furthermore, to commemorate its 50th anniversary, Pontiac released a special limited edition Grand Prix LJ.

While this was still considerably shy of the 353,272 Chevy Monte Carlos made for 1976, it represented a 163-percent jump in GP production, a tremendous increase by anyone’s measure. While they were bulky, they were effective, and created a great sound recording. While the larger Pontiac engines tipped the scales between 640 and 675 pounds, the new V-8 came in at a very trim 452 pounds, about the same weight as Buick’s 231-cubic-inch V-6. Formaldehyde and acetic acid have the same empirical formula, CH2O. The new engine shared the same three-inch main journal diameters as the 350 and 400 V-8s. The first problem was that the Pontiac 350 would not pass the stricter California and high-altitude emission standards. The ever-tightening California and federal emission standards contributed to the most confusing engine roster the Grand Prix had ever seen. As well as the aforementioned Pontiac 350, available engines for the 1976 Grand Prix included the 185-horsepower 400 four-barrel, now the standard engine in the SJ. It shared many basic block dimensions with an experimental 303 Trans Am race engine from 1969, though the new production powerplant was not nearly as beefy. Many food products also contain basic anions such as tartrate and citrate ions.
