We measure speed in miles per hour and torque in pounds for every foot of leverage, but what the heck is a “horsepower” and how is it quantified? Is it really the power of a horse? What would that horse be doing and for how long? I’m having a problem with this for years and
I have a ’67 Chevelle that I have decided to swap in a faster ratio steering box. All the stories I’ve read suggest that an ’88 Monte Carlo steering box is the way to go, but I think they are probably all gone as I can’t find one anywhere. Any ideas on a good alternative?
I’ve noticed that Chrysler is using a new eight-speed automatic transmission for rear wheel drive cars and trucks. I don’t understand how this is more efficient than a more typical four-speed automatic. Plus, with twice as many gears, this transmission has to be really heavy. Care to comment? R.V.

If you think about these overlooked components, they are often severely abused and then blamed when they fail. Using a big-block Chevelle with a Turbo 400 transmission and 4.10 gears as an example, let’s look at the amount of torque applied
I want to install an electric fan in my ‘67 Mustang and I’ve been told that I have to use a relay to wire it properly. I hate to admit this, but I really don’t understand how relays work and why I need one. I know that I can’t just hook the fans to a
I am thinking of using a big block Chevy rectangle port intake manifold on a set of aluminum Edelbrock heads that have big oval ports. Will that be okay or will there be a big horsepower loss? I’ve read that you shouldn’t do this because the engine will suffer a big power loss. I was
