LS1 Conversion - Gauges?

[BOWTIEFREAK383]

1987 Silverado

Will I need to customize the LS1 harness for my existing gauges, change to aftermarket gauges, or have to use late-model gauges?

Haven't seen much on this subject, so I'm assuming that this isn't a very difficult part of the conversion.

Assuming you're referring to you having a stock GM cluster of that year (like this one from my '86):

I would reuse the wiring in the truck that connect to the existing gauges...

??? you say Basically find ways to incorporate your sensors into the LS motor. Oil pressure at rear top of engine like older sbc and use a head holes for temp...I&#39;m using the passenger side head hole for this.

As far as speedo .. I&#39;m unsure since the new combo is electric and yours is cable driven. conversion or new gauge(s) personal &#036;&#036;&#036; call

what size gauges did you use and was there any fabrication needed to the stock bezel? that looks good man, real good.

do you remember how much all of them were all together?
