Gene also claims his head will flow a maximum of 400 cfm at 0. While impressive, these heads would be overkill for your 350 or even a mild 403 street engine. Can you tell me a few companies that make aluminum cylinder heads besides Edelbrock? Check also our 1989 Chevrolet C1500 Pickup manual transmission catalog. You also asked about aluminum heads other than the Edelbrock castings. With its 25-gallon tank, the four-wheel-drive truck got 16 miles per gallon in the city and 20 miles per gallon on the highway. Mount the new regulator and bump the pressure to 13 psi. Rebuild it if it needs it and learn how to tune it because it will offer outstanding part-throttle response.
The length of this trim is 194. We sell only high quality used Chevrolet C1500 Pickup automatic transmissions, with 1-3 years warranty and free shipping. Before we get to the electronic side of things, it sounds like you have a new engine ready to go into the truck. Chevelle articles help, but the Monte is a whole other animal in itself. At wide-open throttle, the computer switches to its base fuel map and the additional fuel pressure will increase fuel flow and assuming the engine needs the additional fuel will increase power. The best approach would be to go with a stock camshaft and a set of Vortec iron heads. Another point worth considering is that buying a camshaft or cylinder heads for a smaller engine like the 350 costs the same as for a 403, but the potential to make more power will always be with the larger engine.
I am flexible with going to a carb setup but would still like to use the stock heads. Stock cams produce relatively low lift, so the back cut will improve flow in that area. Transmission applications fall under the same situation. The approach is to first measure the existing fuel pressure. The length of the truck ranged from 194. The idle quality should still be close to stock.
Can you point me in a good direction for building a naturally aspirated engine that makes 400 to maybe 500 lb-ft that may be pushing it without a longer stroke? The actual throttle plate diameters for the 4. Each one comes with a standard four-speed, automatic transmission with overdrive. You just have to learn to read between the lines. Since 1918, Chevrolet has been an industry leader in its production of popular pickup trucks. Generally, a 1-psi change in fuel pressure from 11 to 12 psi, for example, can be worth roughly an additional 4 percent fuel flow.
To keep the price down, have your machine shop perform a 30-degree back cut to the intake and exhaust valves. The highway rating is 25 mpg for the two-wheel drive and 22 mpg for the four-wheel drive. The engine had an output power of 160 horsepower and 235 foot-pounds of torque. This is a good step, as porting the heads may be more than you can afford, but that can wait as long as the short-block is in good shape. I have been reading Car Craft for almost three years, and I love every issue. In fact, all that room in front of the radiator just begs for a centrifugal supercharger that can be easily mounted on the front of the engine. Stock small-block throttle bodies only flow around 500 cfm compared with a stock Q-jet that flows 750 cfm.
The two-wheel-drive truck had only slightly better fuel efficiency with 17 miles per gallon in the city and 22 miles per gallon on the highway. The difference is the injector flow rates. We would suggest sticking with the stock 5. Jeff Smith: I particularly enjoy receiving tech letters from younger readers. Adding a longer-duration camshaft with more lift will drastically improve airflow and increase power at a higher engine speed. However, the diesel engine, which is a 6. The 403 sports a massive 4.
The Chevrolet 1500 with an extended cab has two doors and seats up to six adult passengers. A 403 Olds will bolt right in to that Cutlass, and even the brackets for the alternator and power steering are the same. As we said, the body panels are completely different, but the many different sheetmetal companies such as Year One, Goodmark, Original Parts Group, and many others offer tons of good stuff like hoods, quarter-panels, floorpans, rocker panels, bumpers, and just about anything else you might need. Do you know how far I could bore it out and how great a stroke I could get? Since you asked about the 350, Dick also gave us some specs on one of his engines that made 431 hp at 5,700 rpm and 434 lb-ft at 4,900 rpm. One of the easiest ways to increase fuel flow is with an adjustable fuel pressure regulator. Buy a recycled 1989 Chevrolet C1500 Pickup transmission and save thousands of dollars. But if you want to get going, you can always buy bolt-on parts for the Olds 350 like headers, an intake, a cam, and even cylinder heads, and then if you find a 403 at a later date, you can use those parts on the new 403.
I have a good standard-bore, two-bolt-main 350 to start with that is assembled with a factory lower end and cam. The four-wheel drive is rated at 16 mpg in the city and 20 mpg on the highway. Keep in mind that raising the fuel pressure increases fuel delivery across the entire engine operating range. This is a bunch more than the Edelbrock head, which Dick says flows around 240 cfm on the intake. The bore and stroke was 4.
