toolman Posted August 3, 2019 Author Share Posted August 3, 2019 (edited) Back in 1971, this 71 240Z was my First and Only Car. It was a Total Wreck- the owner ran it into a large Bulldozer parked on the side of the road. My father owned a automotive body shop which had 5 frame machines. We fixed often repaired totaled cars. So we put it on the frame machine and pulled it straight with multiple 10 ton hydraulic rams. Then the damaged pieces were replaced with OEM parts. I drove the car "stock" for about a year but decided it needed more power. I first checked into modifying the Nissan 6 cylinder motor by Weber carbs, turbocharging and 5 speed racing transmission). But those options were way too expensive. Being a Chevy drag racer, putting a Chevy 327 motor with Turbo 400 transmission seemed like a easy answer. So after gathering all of the needed parts, I pulled the old six engine out and put the 327 in. I had the car running in a week time because I had to use vacation time to do the conversion. At a later date, I put a more powerful 350 and T-5 five speed trans and put metal flares on. In 1988, I bought my second car 88 Chevrolet Astro Van for business. My 240z was basically sitting in the garage since that time. So I owe it to spent some time restoring it as the best that I can do. I hope this story explains my restoration. Back to the restoration: I put the Wheel Fitment Tool on the car to check the wheel alignment out. But first, had to remove the strut coil spring as it won't allow the body to drop as there was no engine weight and accessories. Took out spring Put the Wheel Fitment Tool to test it out. Wooden blocks were placed under the lower control arm to adjust ride height. The car is still on a dolly which lifts the vehicle about 1" higher than a stock Z. Using a Tool Aid Wheel Alignment gauge to check Camber readings. A carpenters square shoed the hub to be close to zero so I set the gauge to zero degrees, After checking the Square with the ground, I reversed it to better demonstrate camber. By tilting the straight edge top outward(away from the car) to stimulate Positive Camber. Positive Camber To stimulate Negative Camber, I titled the top of the straight edge inward( toward the engine compartment). Negative Camber I think there was a misunderstanding about what I trying to accomplish. In my particular case, I am trying to eliminate as much Negative Camber that I can. Lowering the car with shorter springs, lower ride height, extra wide wheels,etc will create a lot of Negative Camber. Shortening the lower control arms, upper camber plates, modified spindles,etc maybe utilized to provide Positive Camber to achieve alignment. My car will be basically a Street Car and not a Race Car requiring 3 degrees Negative Camber. Now, you can even change front and rear crossmembers to get the alignment that you want.
