"It's not a heap, dad. It's a classic." That's harder to justify when your classic muscle car won't start. Nothing like a high-compression V8 combined with a battery that hasn't seen a charge for a ...

Ignition timing is like seasoning: some is good, but too much ruins the results. Bumping up the ignition timing on pushrod 5.0s is a time-honored trick to wake up the under-hood lump. The EFI system ...

Welcome back for Part 2 of tune-up tips for your older Corvette. Last time we talked about tricks of the trade when setting points. This month we will talk about setting ignition timing. The most ...

'The new darling of the engine-swap set is the GM Gen III family of small-blocks that includes everything from the lowly 5.3L truck engine to the LQ9 6.0L all the way up to the swarthy Corvette LS7 ...

According to NGK, adding 10 degrees of ignition timing at idle will raise the spark plug temperature anywhere from 180- to 210 degrees Fahrenheit. This means that adding just one degree of ignition ...

There's a tiny silver can on the side of most distributors that is easily the most misunderstood component of any distributor-based ignition system. Feared by many, and ignored by many more, the ...

When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains constant ...

underway before tdc is reached. This gives a maximum cylinder pressure (and work output). This ignition timingcondition is about 20 degrees of crank rotation before tdc, i.e. 20 degrees btdc. From, ...

An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...
