I used all stock mechanical gauges in mine with the LS swap. My gmc has a 60psi oil pressure gauge stock though. Only part I did mod was to copy the amp to volt gauge swap mentioned above. I however like my faded tan guages so I simply added 2 small brown dots to my amp meter (now volt meter). The lower mark is 12v and upper mark is 16v so i kno if its at or below the 12 or at or above the 16 dot that theres a problem…..in the middle then all is well! Im the only one that drives it so i kno what im looking at. All other gauges work great!
