Hey guys, so I got my 85 camaro about 2 months ago (I'm pretty sure it's a Z-28 as it has a 305 Carburetor, and no Iroc-z markings). The stock gauges did not come with a tach. and when I crank the car it feels like it's idling fast even after warming up.

1.) should I look into getting an aftermarket tachometer?

2.) is there any possible way to control the idle (how fast or slow it is)?

I'm obviously a noob at all this...BUT I"M TRYING!!!

this is the 3rd time i've posted this same thing but in a different section...hoping to get somme resolution haha
