When RPO U14 was ordered (SS or not), the round pod dash was used. The three large pods (from left to right) included the tachometer (with oil pressure warning lamp), the speedometer/odometer (and automatic transmission indicator if column-shifted), and either a blank pod or a clock. An amp gauge occupied the top left small pod; water temperature and fuel level gauges occupied the two right-side small pods.
The tachometer was located in the former fuel gauge pod and had an oil pressure warning lamp built in. No oil pressure gauge was offered, which seems rather odd. Many enthusiasts were more concerned with oil pressure than with ammeter readings. RPO U14 could be ordered in any V-8 Malibu sport coupe, convertible, sedan pickup, or Monte Carlo, whether SS Equipment or not.
The tachometer code in box 72 is 938 on this LS5 Chevelle. It should be 985. This computer programming error was unique to the Atlanta assembly plant. The Atlanta, Georgia, plant was the only one to use the “MALIBU COUPE H/TOP” words on sport coupes.
Arlington, Texas; Baltimore, Maryland; Kansas City, Missouri; and Van Nuys, California, assembly plants coded the L34/LS5 tachometer in box 72 correctly as code 985. The Flint, Michigan, assembly plant did not use this form of broadcast sheet.
There is a lot of misconception about the optional gauges offered. Even SS Equipment Chevelles only came with a fuel gauge standard; gauges and a clock were optional. There is no such thing as “SS gauges.” There was one gauge option in 1970, RPO U14 Instrument Panel Gauges, and it came with an appropriate redline tachometer, an ammeter, and water temperature gauge. The 307- and 350-ci engines received a tachometer with a red-line at 5,000 rpm, both the base 396 and 454 engines received a tachometer with a redline at 5,500 rpm, and the optional 396 (L78) and optional 454 (LS6) received a tachometer with a redline at 6,500 rpm.
As a result, all documented Atlanta SS454 Chevelles with the base engine received the lower, 5,000 rpm redline tachometer. When RPO U14 was ordered there was a three-digit code on the build sheet indicating which tachometer the car should receive. These three-digit codes are 938 for the 307 and both 350-ci engines, 985 for the base 396/454-ci engines (L34/LS5), and 983 for the optional 396/454-ci engines (L78/LS6). Unfortunately, Atlanta had programmed its computers in error, so when an LS5 SS454 was ordered with RPO U14 it received the 307/350-ci engine 5,000-rpm redline tachometer, code 938, instead of the 5,500-rpm redline tachometer it should have received.
This July 1, 1970, Atlanta, Georgia, build sheet shows RPO U14 IP GAUGES but not the RPO U35 clock. The clock was only standard on the Monte Carlo with or without RPO U14 IP GAUGES optional gauges.
