Q: Last year, I rebuilt my Ford 300 cubic-inch straight-six engine. The head was shaved .010”, the valve seats were reground, and the crank resized. The block was bored and cleaned also. The cam is a Competition Cams 260H grind with matched lifter, pushrods, and rocker arms. I also installed a new oil pump. The problem
I have a ’66 Chevelle with a small-block and a TKO five-speed that’s been recently upgraded with better synchros. With the trans back in the car, I’ve noticed a bad vibration in the driveline at speeds above 60 mph. What’s weird is that when I have someone else in the car, the vibration is reduced.
DECKED truck bed storage systems have become increasingly popular as a method of improving the utility of pickup trucks and vans. Equally useful for contractors storing tools and supplies as they are for outdoor sportsman storing hunting and fishing equipment, DECKED truck bed organizers are made in the USA, and built to last for as long
Q: I have a question about engine compression. What would the following compression ratios be in terms of pounds per square inch (psi) of cylinder pressure? 8:1 compression 9:1 compression 10:1 compression 11.1 compression The reference engine is a small block Chevy 350 bored .030 inches over. A: Cylinder compression and cylinder pressure are not directly related
It’s time to debunk some brake rotor myths. Myths that, on the surface, seem to make sense in many cases. But ultimately, believing these myths won’t resolve actual brake system problems. These myths can hurt an automotive technician’s ability to diagnose common brake problems and solve them effectively. This is why people complain about taking their
We’ve built and tuned so many supercharged engines over the years, we’ve lost count. And every time we build a Roots-blown engine, the thing we least look forward to is setting up the carburetor linkage. If the engine is running a single carb, it’s an easy job. Dual carbs mounted inline is almost as easy.
Q: I am in the process of building a 383 stroker engine for my 1989 Camaro. It should produce about 450 horsepower (the current engine’s a V6). Will the stock rear axle be able to handle that much power? If the axle is no good, which one would you recommend using? Will I need to install
Rust is the archenemy of any restoration project. Fortunately, the aftermarket has developed some very effective products for battling rust. In this post, we’ll inform you about of these rust-battling options and show you how well they work. We’ll do so primarily though the help of paint and body expert Kevin Tetz, creator of the Paintucation video
You’ve increased your Jeep’s tire size for improved ground clearance, and then you lowered its gear ratio to take advantage of the taller tires. But now, with the taller tires and lower gears, you feel a significant decline in stopping power. That’s because the heavier tires require better brakes to slow and stop them. Generally,
Volumetric efficiency is a term that’s tossed around quite a bit when talking about internal combustion engines. However, surprisingly few people understand what volumetric efficiency is and how it actually affects engine performance. In this post, we’ll discuss volumetric efficiency, provide the volumetric efficiency formula, and show some examples of how it applies to specific engine examples.
