What should timing be on small-block Chevy?
Depending on your cylinder heads, compression ratio, camshaft, and centrifugal advance curve in the distributor, “normal” base timing for a street high-perf small-block Chevy is somewhere in the 12- to 18-degree before top dead center (BTDC) range, with total timing at full centrifugal advance about 34 to 36 degrees …
What should my ignition timing be?
The ideal ignition timing occurs (at any given rpm) when maximum cylinder pressure is achieved at roughly 15 to 20 degrees after top dead center (ATDC). This is when the piston and rod combination create maximum leverage on the crankshaft.
What should ignition timing advance be at idle?
between 5-20 degrees
Most engines have between 5-20 degrees of ignition advance at idle. This is referred to as initial timing.
What is the best ignition timing?
The ideal ignition timing for power occurs just before the point where detonation or pinging takes place. Correctly timed ignition will cause peak cylinder pressures to occur around 12 to 15 degrees after TDC.
How to fix Chevy 305 problems?
Unplug the electrical connector on each injector on the fuel rail (located in the front of the engine) one at a time. Make note of the idle speed. Then, reconnect the electrical connector. Do this for each injector and if you notice that the drop in idle speed is roughly the same for each injector, then they are operating normally.
How do you change the oil on a Chevy 305?
Purchase a set of 1985 to 1991Corvette (L98) cylinder heads and perform some port clean-up to enhance flow. Gasket-match the intake ports and exhaust ports by laying an old gasket atop the mating surface, spraying it with a light coat of white spray paint and then removing the white ring around the port with a carbide cutter bit.

Should you build a 305 Chevy?
Yes everyone is correct the 350 is the best bang for the buck and 30s are more expensive to build. But i am building a 305 for my Nova right now just to get the 6 cyl out of it. Im just putting a 262/272 summitt cam, 625 cfm road demon JR carb, and high volume oil pump and Edelbrock intake on mine.
