I have a 1970 Chevy Nova. The speedometer runs 15 miles low all the time. Do I just need to replace the speedometer cable or is there another problem? Thank you.

Go to a chevy dealer and have the ratio of your rear axle on hand. they can get the correct speedometer gears for your transmission

count the teeth on the pinion and ring gears. if you have 41 teeth on the ring gear and 8 on the pinion gear your ratio would be 3.28

all you do is multiply the two numbers.

then the tire size is needed going by the current year that tires were manufactured for this car

1988 Chevy Nova started running real bad and

It really depends on what you have under the hood. And how many miles it has on it, I have an 88 transam, it has 250,000 miles on it . Still will do donuts in the parking lot. everything is original. Taken care of. But it is old and tired. Rebuilding it soon. Repost with TBI,TPI , or carb..All these make a difference. besides your engine is just worn out.

1970 chevy nova gas gauge problen

Well friend, you know the dash gage is good cause that was a proper test procedure. Since your not getting proper readings it has to be the sending unit. Pull it apart and clean the rheostat with a pencil eracer and light pressure, the assemble it and try it again. if still nfg, replace the sending unit. they're cheap from any auto parts store.

1987 Chevy Nova Speedometer is bouncing around like crazy + making a LOT of noise. Is it just the cable that needs to be replaced or is there another part somewhere?

It would be the cable. You can try pouring some oil down the cable cover. That should clear up the noise and may smooth out the jumping. If it doesn't smooth it out then the cable will need to be replaced because the ends are getting worn.

If you are having trouble finding a new cable then call your local cab companies. Taxi meters used to run on a cable and the place they got those cables done at likely still has the tool to make cables with. Hope this helps.

I need a detailed diagram of a 307 V8 motor for a 1970 chevy nova

Your best bet is to get yourself a repair manual from chiltons or strate from G.M. Most all your major auto parts stores have web sites you can go to and get the information and diagrams you need also. A repair manual is best. You also can get them thru Year One. National Parts Depot. Original Parts Groupe, Jegs, and Summit Racing. for your particular project.
