But did you ever wonder why the Willys became so popular starting back in the 60s with Gas class drag racers? When the popular Willys coupes were introduced in 1937 they were marketed as 40 MPG economy cars. With a 61 HP 4-cylinder engine capable of zero to 60 in 18 seconds, they didn’t get an MPG figure that was double what most on the road had through advanced engine technology. It was simply through light weight! And that’s what made them popular with gasser builders. With a curb weight only slightly less than a Model A of a decade earlier, the Willys also had better steering and brakes. More importantly, though, it was much more streamlined than a Model A or Deuce which had front fenders that were as streamlined as running into the wind with a sheet of plywood. Take a look at the stock Willy chassis above and note that the side frame rails use only C-channel construction with thin 7/64″ material! Today, though, even with a mild 350 HP engine you’ll be increasing your Willys’ horsepower by over 500% and it’s weight by over 25%. Get ready for some problems: not only in handling and potential failure, but also your body work getting torqued and paint cracked — to say nothing of keeping doors aligned and opening. Hey, even if you’re thinking additional crossmembers and reinforcement, just remember that it’s just an addition on a thin steel frame that’s 75 years old! After a few years of mishaps even the NHRA changed the rules to allow Willys Gasser owners to ditch the original flimsy frame. Our Willys gasser frame plans show you how to build a modern frame using strong, readily available and economic 1/8″ rectangular steel tubing! And our plans can be used to build a modern chassis for a 1937 to 1942 Willys coupe, sedan or pickup truck. If you’re shopping for a newly built Willys Gasser chassis, though, get ready to spend over $5000 for something that was designed only for the drag strip. But, there’s a better, much cheaper way.
