Now, yes. Not 30 years ago when I redid the dash on my '57 1/2 ton.
Note the 270 degree oil pressure gauge. It was only on big trucks, as was the ammeter.
The tach is a Sun SuperTach II that originally had a 270 degree, 8000 RPM swing. I refaced it using a set of GMC dash decals and an Xacto knife. Making it run 4000 RPM at 270 degrees only involved switching it to 4 cylinder mode.
'57 GMC 102, Original 347 V8, HydraMatic, 3.08 rear gear, added A/C, disk front brakes, HEI, AFB carb, '98 Honda Black Currant paint. T-boned and totaled 10/12
'52 GMC 152 Stake Bed, Original 228, SM420, added A/C, HEI, disk front brakes, '67 Chev 3.55 rear gear. Gets used as a real truck.
