When I swapped in the 5.3L, I wanted a nice tachometer, so I found an early Sun 7k tach. I had it reworked with new electronics, specifying that it needed to read a 4 cyl. engine signal from the PCM. After spending lots of money to refurbish the gauge, I installed it
and guess what! It was rebuilt to read an 8 cyl. signal. Great! Now what! So, not wanting to spend major bucks again, I contacted Speedhut and had them build me a new tach. Less money, and programmable too!
Being as their gauges are "in dash" pieces, I fitted the tach. with an older Sun tach pinch cup. It's only a 6k tach. but I'll never spin the engine above that and it's easier to read because of the wider "spread" of the numbers. A nice piece. Responsive too
