It's not often that things go the way they're supposed to these days when it comes to building cars. There's more than enough variables to keep you up at night hoping for some kind of magical dream to show you the answers to cars, the universe, life, and the sock gnome.
We're not sure about most of those, but luckily there are a few solutions to the car thing. Even with all the different avenues to take, you'll still need to build the car to transfer your engine's power to the ground, as well as be able to hold it together out on the road instead of having all those ponies go out the window. One thing that'll help both of these aspects is to stiffen up the chassis of any car and especially on a unibody car like the Nova and Camaro. The only substantial sections of frame these early cars have are the front subframe, which bolts to the floor of the car and doesn't really extend beyond the doors, as opposed to a full perimeter frame like a Chevelle. Redirecting the power from the sheetmetal in the body to staying in the chassis will really wake up your ride. Subframe connectors are one of the easiest ways to do this; just ask anyone at the strip or even on the street.
Global West Suspension Systems knows this better than just about anyone, coming from over 25 years of experience building suspension parts that don't just look pretty but actually work. They do all their own R&D and manufacturing in-house at their facility in San Bernardino, California. It's filled with parts, machine tools, welding jigs, and anything else that a state-of-the-art shop should have. Not only do they have subframe connectors, but trick A-arms and many other things that your musclecar might need. Follow along and call them up with your needs to get the ball rolling on a car that works for you!
