Will a big block Chevy distributor fit a small block Chevy?
NO.
Depends on the year. On the pre-fuel injected motors, all Chevy V-8 engines used the same distributor. Use some common sense, a 1968 distributor is not the same as a 1980, but you get the idea. Use one from the same era as your vehicle.
How do you drain gas tank 1990 Chevy 1500 305?
There are two ways to drain the fuel tank... One is to siphon it... The other is to drop the tank from below remove the fuel pump assembly and then turn the tank over to pour the fuel out. I would recommend using both methods together if you need all the fuel out or if your changing the fuel pump. Siphoning will get the majority out but not. and if your dropping the tank anyway siphoning will make it lighter and easier to work with.
How do you replace the valve stem seals on an 88 305 small block Chevy engine?
You can purchase a kit at most auto parts stores that includes an air fitting and a compression tool to remove the locks and change the seals.
Where besides near the distributor is the oil pressure sending unit on a 1983 Chevy 305?
On drivers side screwed into the back of block behind intake with 1wire plugged on to it.
Yes you do.
well this could be a number of things... cracked distributer cap? rotor wore out? cam problem? distributer gear wore out? timing chain jumpin? one of these would be my first guess
How do you find top dead center on a Chevy v 6 229 3.8 liter engine?
The # 1 plug is the plug at the front of the engine left side on a transverse mounted engine. Front drivers side on a longitude mounted engine. Remove the spark plugs, pull the coil wire, and turn the engine over until the #1 plug is at it highest point on the compression stroke. You are now at TDC.
What is the spark plug gap for 96 Chevy 305?
I belive its .35 to make sure go to a library and look it up in a chilton's manual or call your local Chevrolet dealers service department. They should know the answer for sure.
Is 6000 rpm too much for a stock 305 small block Chevy?
yes 6000 rpm on a 305 is WAY too much the max is 4500 and 5000 and that's pushing it. A stock small block Chevy has plenty of power no need to wind it up that much!!
When that type of combination has been used by the OEM the compression ratio was around 10.5:1.
Timing should always be set without vacuum hooked up. Initial timing should be around 12-15 BTDC at idle - around 24-26 BTDC at 3000 RPM's - and around 36-38 BTDC at 3000 RPM's with vacuum hooked up. There's (3) stages to timing on sbc:
10 degrees initial
10 degrees mechanical advance (the weighted springs in the distributor)
10 degrees vacuum advance These will vary depending on carb/intake/cam setups. Hope this helps!
The lower the compression, the more timing you'll need. Could be up to 18 degrees at idle (42 degrees total.) I'd start at 38 degrees total and go up and down a little at a time until you find the best performance.
That cam likes compression. The more the merrier. At least 10:1.
How do you replace the intake manifold gasket on a 1990 Chevy 1500 4x4 305?
Hey John==It is quite involved. Get a manual from the local parts store and it should have pictures and everything. Good luck, Joe
What is the cfm rating on a stock carburetor on a 1986 gmc sierra pickup with a 305?
Most of the Rochester carbs were factory rated at 750 cfm; but this was a airflow rating only; unlike performance carbs that are flowed with a air and fuel mix. When the factory Rochester carb is wet flowed like a Holley carb, the flow rating of the carb is adjusted to around 470-500cfm. I hope this helps you. Mark
How to fix the heater hose that is inserted into the intake manifold on a 1995 305 v8?
The connector into the intake manifold of a GM 305 and 350 has been known to be quite fragile. If the connector has broken you have little choice but to replace the manifold.
What is the gas millage of a 1983 Chevy silverado k10 4x4 short bed with a 305?
Driving gently you might be able to get up to 15 or 16 on the highway, around town would be less.
How to flush 1978 Chevy Caprice carburetor engine 305?
Flush?
Their are rebuild kits for most carbs, no flush kits, buy a rebuild kit, need to take it apart, run it overnite in a carb bath optimally, if none is avalible, clean it inside and out with a good carb cleaner.
not a job for a n00b, sry.
You can try a full tank of fuel and a can of Seafoam Fuel Cleaner. It may of may not help. I have seen it works wonders. You have nothing to loose but the $7 it costs.
