links to ignition related info you can use

Postby grumpyvette » November 24th, 2008, 10:23 am

this may help,
BUT remember each link has different and useful info,
youll only find exactly what you need to know
by reading thru the links UNTIL
youve found what you NEED to KNOW, and 90% of the time..
youll learn a good deal of stuff,
that will come in very useful later on other projects ,
while your wading thru the info
wet, loose, or broken electrical connectors or corrosion on connectors, is also possibly a cause of intermittent problems

just some info solid core ignition wire and EFI/computer controls don,t always play well together
on my 1985 corvette I use TAYLOR 10.4 MM SPIRAL supression ignition wire

http://www.racenet.net/elec/taylor-thunder-volt.php
I have tried several other types, so far all other types cause intermittant problems with the ECU,or the electronic gauges in the dash from RF, I found this out naturally by tring to find what was causeing those weird glitchs in the way the engine ran sometimes, so just keep in mind that solid core ignition wire and computer controlled efi and ignitions don,t always work well together and the problems caused are not allways easy to spot or constant! BUT I can say that the 10.4 mm ignition wire does help immensely in limmiting the RF

heres optispark info also

THE cam gear rotates exactly once for each two times the crank rotates,the cam gear lines up at the 12 oclock crank and 6 oclock cam gear orientation when the #6 cylinders on the compression stroke, rotate the engine one complete revolution and the cranks again at 12 oclock but the cam gears index mark is now at 12 oclock, indicating the #1 cylinders at the compression stroke, you use the 12/6 index to install cams simply because its easier to align correctly ,visually, but you need to rotate the engine to the 12/12 orientation before dropping the distrib back in, the distrib won,t fully seat unless the oil pump drive shaft seats up into the distib gear, as you remove the distrib the helical gear interface tends to turn the pump drive shaft slightly, you can use a long flat tip screw driver to turn that back to the correct location and with a bit of practice youll learn to gauge the amount the rotor rotates as it seats into the cam gear.



The CLOYES true roller style is vastly superior to the factory link belt design

how come its 180 degs out of phase?
I get this question all the time, well here’s something I see lots of guys don’t understand, ONCE YOUVE INSTALLED A CAM WITH THE TIMEING MARKS YOU MUST ROTATE THE CRANK 360 DEGRESS BEFORE DROPPING IN THE DISTRIBUTOR, while its true that if the, timing marks are positioned so the crank is at 12 o,clock and the cam gear is at 6 o,clock that the cam lobes will be in the position that fires #6 cylinder that HAS NO EFFECT AT ALL (on finding TDC,) for aligning the degree wheel with TDC,or THE timing tab pointer, for degreeing in the cam, the piston passes thru TDC TWICE in every firing cycle once on the firing/power stroke and once on the exhaust stroke, the cam rotates at exactly 1/2 the speed of the crank so to make it easy to line up the marks they install it with the marks at the closest point 6/12 for easy indexing, rotate the engine 360 degrees to the #1 TDC power stroke and the crank gear will still be at 12 oclock 12/12 but the cam will be at 12 o,clock also, rotate another 360 degrees and your back where you started. its simply easier to index the cam at the point where the index marks align closely. look at how the cam lobes themselves open the valves when the cam is just installed the #1 cylinder valves are slightly open and the #6 are closed per "Lunati" ‘’YES YOU ARE RIGHT - WHEN CRANK IS AT TWELVE AND CAM IS AT SIX THEN #6 CYL IS FIRING AFTER YOU LINE UP YOUR MARKS AND INSTALL GEAR THEN ROTATE YOUR CRANK ONE REVOLUTION AND THEN DROP THE DIST. IN - AT THAT POINT

drop the distributor in with the rotor pointing at the #1 cylinder, and YEAH! it physically possible to get the distributors rotor to point at any place you want it too by changing the oil pump drive shaft alignment with a large flat blade screw driver while the distributors out of the engine and that's easily changed, but to do it correctly,you want the rotor to point at the #1 cylinder on the compression stroke, so pull the #1 plug, get a large ratchet/socket on the damper and put your finger over the open plug hole and slowly rotate the engine by hand in its normal rotational direction until you see pressure build under your finger as the rotor approaches #1 cylinder location on the distributor base which you should have marked as its supposed to be in direct alignment between the distributor and the number 1 cylinder on the engine, remember the distributor and cam gears are helical and the rotor turns as it seats so compensate slightly. and the rotor should be just coming into alignment as pressure builds under your finger, once that's done re-install the distributor cap and plug and use a timing light to set the timing, you normally want about 6-12 degrees BTDC at idle and watch it advance to about 37 degrees as the rpms build to about 3000rpm
