47-54 gauge questions 6 cyl/8 cyl differences?

[73kay]

Ok I'm looking at the classic parts catalog and noticed that they have difference temp gauges depending if it's a v8 or a i6. I have a 54 Chevy 235 motor but I want to keep my options open down the road of its not rebuildable to throw in a crate 350.

Replacing my oil pressure to 60 lbs is a no brainer. Battery gauge should be easy? I converted to 12 volts. My fuel gauge is another issue. I have a extra c10 tank with a new sender collecting dust in the garage so I gotta research if I can find a stock gauge with 90ohm range.

I have my old gauges and saw you can get a sticker to give them a facelift but with all these changes I might as well get a whole new set maybe.

Appreciate your help
