i just got done swapping a 355 into my cutlass, it previously had 1 v6. it has the factory ralley gages. how do i switch the tach to work with a v8? is there a switch of some sort like on a aftermarket tach? i have not pulled it out yet so i thought i would save some time by asking on here. thanks!
cutlass tach 6 to 8??

if I remember right there should be a jumper on the back of it that's marked 6 or 8. so, yeah its that simple 😀
Thanks! just wanted to make sure before i tore into it tonight, would suck to do all that work and have that not be the spot to change it. 😀
