I have an all-steel ’41 Willys with an all-aluminum 498ci Keith Black HEMI with a Don Hampton 8-71 supercharger and an EFI system using electronic fuel injectors located under the hat. The engine makes killer power and it has a TH-400 trans behind it with a 9-inch rear and a spool. The car cruises down
I recently read a story in a national publication that struck me as interesting and worth dissecting. The story tested the addition of a tall, long runner EFI intake manifold versus a production LS1 intake. I’ve recreated the curve in the charts and graphs included here. The test showed that the baseline combination using the
I have a small, 12-ounce bottle of DOT 4 brake fluid that’s been on the shelf for at least a couple of years. I was going to use it but two things got my attention. First, the plastic bottle had collapsed–almost like it was sucked in. That made me wonder if the fluid inside
[portfolio_slideshow id=32476] Drum brakes have their place—just not on any kind of performance car that’s driven with enthusiasm. In our experience, drum brakes are good for one and perhaps two aggressive stomps on the brake pedal from speed and then, like Douglas MacArthur’s old soldier, they just fade away. That’s why Summit Racing offers an
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. It’s interesting how the number of
I’m thinking of upgrading the front disc brakes on my ’69 Chevelle with better pads. The car is a 454 with a Turbo 400 and stock front disc rotors and calipers and runs in the low 12’s at 110 mph. I want to get it stopped quicker but I can’t afford those expensive 14-inch rotor
[portfolio_slideshow id=31013] Axles aren’t usually a topic of great discussion—until one fails or otherwise needs replacing. 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
