How do you remove a steering column from a 1969 Chevy Nova?
First, disconnect your battery, now, if you open the hood, you will find a flexible couplig about half way to the bottom of the column, you can unbolt that, then, sitting inside the car, under the dash you will find a U shaped brace fastenig the column to the underside of the dash, (it usually has 2 bolts, but depending on the model may have 4), then you must detach the wirng plug (for the turnlights and horn, it is close to the U shaped brace). then remove the two screws in the back of the steering wheel which hold the sterering wheel padding, once removed, there is a circular sliding switch which activates the horn at the center of the wheel, be sure to detach the wire fastened to the steering wheel which comes through the steering column.
its running too rich down tune youre carb
No the first and most important thing you can do is replace the cam and heads. Everything else is junk. get competition headers from hooker since they are just about the only headers you will find for that car. Then just get some Jegs aluminum heads and a cam with .45 lift max unless you want to get really into it and a cam with a duration of 201 intake and 204 exhaust 105.3 lobe center angle and 105.5 intake centerline. Then get a 390 to 450 cfm Holley carb unless you have one tuned for a 305 and I suggest Holey because they are 10 times better than any universal carb you can find. Dual plane manifolds are highly overrated I suggest a Torker 2 manifold it work great I have it on my 76 nova 305. Your compression ratio will likely drop with the new heads because most smog 305s have dish pistons meaning you have small combustion chambers, which is why a set of 350 heads meant for flat top pistons don't work. Also get MSD it'll be about $500 for the whole setup but its worth it. Go to Summit racing for the cam because you can order a custom grind cam from them with lifters and all for really cheap. But make sure your tranny can handle this because 4th gen novas like that come with the THM-250 instead of the THM-350 for weight savings if you have to get a street-fighter transmission and components from TCI it'll be about $1000 for the whole tranny setup with torque converter. Keep stock gears unless you want your highway driving to suffer. If you want disc brakes in the rear get a second gen camaro or firebird/trans-am with disc brakes and posi. Now you need to get wider tires then those 215s you have and swap out for some 245s or 255s.
AnswerFirst off, you need to do a complete tuneup- wires, cap and rotor, plugs, new K&N air filter, fluids and filters (including fuel).If you have the stock Q jet- you are limited. If you have an aftermarket carb, your power potential is greater.
-1.6 rockers- makes the engine *think* it has a bigger cam. I use and recommend aluminum roller rockers.
-Headers- no larger than 1 3/4, 1 1/2 will make the best torque.
-New free flowing exhaust- 3" if you are running a Y pipe, 2.5" if you are running duals. Good mufflers (I prefer Flowmaster for sound).
-New intake manifold (Edlebrock Performer/ Performer RPM).
-New carb- your choice of brand, no larger than 625 CFM.
-Add an electric fan- get rid of the clutch/water pump driven fan.
-Underdrive pulley's.
-New gears (make you 'scoot' quicker).
-Remove your emissions junk if you can- it's ugly and heavy. Did I mention it's ugly?
If you really want to get down and dirty, get a new cam and 416 heads- 416 heads have 58cc combustion chambers, and will probably increase your CR. Never use 350 heads on a 305- it will only cause problems. If going with a new cam, ALWAYS use new valve springs and hardware. I'd recommend a cam with around 212-218* duration at .050 on the intake side.
keep in mind that a 305 has a small bore size and a "good set of cylinder heads" will not work because of engine block interference with larger valves. It is difficult to make allot of power because of this problem. A 305 shares a crank shaft with the 350 ci. It has a much smaller bore size to reduce the engine size. Its not a good design. It was done to increase fuel mileage in the 80s. Kind of a band aid fix. If you like the small ci Chevys use a 327, 302, these are high revving engines with a 4" bore and have allot of potential for power gains
The capilers and discs from an Astra/Cavalier GSI will fit without any problems if memory serves, although you may need to fit bigger wheels. Due to larger discs though, you may need to fabricate a bracket to fit the caliper. The best calipers are the V6 Vectra ones, although the discs won't fit as they are 5 stud fitment. Many companies sell kits though to fit V6 calipers, and these come with large 4 stud discs and all the brackets etc. If your not aiming for mental power, you might be as well upgrading the standard Nova brakes with some better pads and discs. The EBC 'greenstuff' pads and discs work really well. This would also be a more cost effective option. and though may cost a tinny bit more than other in its range its really good car to drive and really worth the money for speed and comfort
How does the heater core for a 1968 Chevy 2 Nova come out?

How do you fix a horn for a 1978 Chevy Nova?
Apply 12 volts directly to the horn an if it blows it is good. If not it is bad. Check the fuse for the horn. Check the horn relay. Check the horn button in the steering wheel. Check all wiring and the ground connection.

What is the oil filter size for a 1972 Chevy Nova?
The book calls for a Fram, ph30, for that car. The ph13, is the same filter, but longer, and will probably work for your car. It is a much better filter, as it has more filter area. Fram only lists it under the heavy duty applications, like a 3/4 pickup. Either way you go, you will need the big filter wrench.
What is the rear differential fluid capacity using synthetic oil on a 2000 Chevy truck?
Typically you fill to just below the fill hole, I usually use a smaller Allen wrench to check it. if it is to about the middle of the short end I just leave it. This is usually pretty close to two quarts.

How can you fix the headlights on a 1973 Chevy Nova?
First test to make sure it's not the headlight it's self that is broken then check for an shortage or cut in wires if no you can cut wires strip the plastic outline that protects it and put the right colored wires back together if not take it to a mechanic and get new wires
Should be somewhere around 350-400 hp, depending on how well the combination matches. Sounds like a combination that needs a lot of gear and loose convertor or a 4-speed.
