This is the original OEM gauge panel and all are still working. Note that the max MPH number is 115 and is as conservative as the RPM redline of 5500 RPM. Remember, these cars were sold with a 305ci or the optional 350ci and both were smog engines. Power ratings were so anemic that the 6,024 buyers of these in 1987 really had to strain their imaginations to think they were getting cars like those going around Daytona and Talladega at +200 MPH. The Temperature gauge shows they were to run at 220 degrees (emissions) and average oil pressure was to be 30 psi. I can tell you that Ben’s engine, or mine for that matter, don’t go over 180 degrees and oil pressure does not go below 35-40   PSI hot and idling. 


To get the shifting right, Ben is using a “Cheetah” shifter, but with a reverse shift pastern for the HD TH400. This is an outstanding shifter and one I would love to have in my G-body.

A mix of stock and Autometer instruments, deliver sensory Information to Ben’s neural-net so he never feels deprived. The still working like new stock instrument cluster resides where the factory placed it; Speedometer, Tach, Fuel level, Water Temp and Oil Pressure and Volts. Mounted into the dash from the middle of the car to the right side are the direct reading Autometer gauges; Water Temp, Trans Oil Temp plus Fuel Pressure thanks to a remote pressure transducer keeping dangerous gasoline out of the inside of the car. An Autometer Elite 8,000 RPM tachometer is the gauge mounted closest to the driver.

The exterior of the car had been treated to a lot of block sanding before it left Fisher Body (GM bodies are made by Fisher Body in a factory that dumps into the staging area of the car / truck assembly plant.) Bodies come one-by-one through a single car garage door opening to be lined up in sequence to all the rest of the components of the car that Chevrolet or another GM brand runs.  Fisher makes the sides as smooth as a beautiful young woman’s skin and just as straight as an age-old mirror. The body is the stock GM Silver; only the roof has been repainted because of sun-damage. Nothing else has negatively happened to Ben’s G-body since he purchased it in 2012. The $14,500 he invested since then improved an already fabulous car.

Note: When it comes to tuning your collectors to the correct length, paint a black stripe with a Sharpie pen and let it dry. Then fire up your engine and run it for at least five minutes at different RPM’s. After the car cools off and you can touch the header pipes get back under the car and look at your black stripe. Somewhere along the stripe you will see the pen mark burned off. It should be after the header collector. If you are going to use 2.5 pipes I recommend you extend the collector by adding another length of 3” pipe to where the stripe burns off. If you have 3.5 collectors and plan on using 3” pipes, extend your 3.5 collectors to where the paint burned off. This will maximize the torque and power from your engine and your headers.
