Easily adjust the mechanical advance with the supplied. Accurate and maintenance-free magnetic pick-up never needs adjustment. The only thing is that the early carbureted mustang distributors have 3 wires. I need to buy the ignition system and wanted to go basic. My question is about the coil/distributor wiring. High output ignition module produces quick starts, smooth idle and improved mid range performance. So I got this late 80s fuel injected 302 mustang engine. Only three wires to connect for a simple installation. Vacuum advance is to make the car more drivable, and only affects part throttle operation. MSD Billet Marine Distributor - Ford 429/460 V8. #FORD 302 DISTRIBUTOR INSTALLATION FULL#This would be the timing at full throttle.įinally the vacuum advance is set. My 93 F150 302 has an issue with a slightly rough idle, a slight hesitation when. It advances ignition timing to about 35° BTDC, with a curve from base timing to "all in", again without vacuum. The contact stated that the throttle cable was exposed and installed. Figure 1 Gear Installation Specifications On the MSD FE Dis-tributor, PN 8594, the spec is: 3.045. Next, mechanical advance is set, usually reaching is "all in" maximum by 3000 rpm. CAUTION: If the gear is installed improperly, severe damage to the distributor and/or engine block will occur Press firmly to take out all end play before mea-suring. Base timing is usually around 10° BTDC or so on old v8s. Note: The Distributor is supplied without a gear. Base timing is also performed at idle, so the mechanical advance is also not affecting it. MSD Ford Billet Distributor PN 85821: 289/302 without Distributor Gear Important: Read these Instructions before attempting the installation. This is done with the vacuum to the distributor disconnected to remove the effect that it has on the timing. #FORD 302 DISTRIBUTOR INSTALLATION FREE#To accurately set the timing curve, there are 3 steps. Depending on who writes the instructions, the method and the dimensions can be different, but in any case, the objective is to press the distributor gear on such that when the distributor gear bearing face is resting on its mating surface in the block, the distributor shaft should be floating in the middle of its free play. Mechanical distributors use a centrifugal system to move the timing plate as engine speed increases. The other time an engine needs it's timing advanced is during high rpm operation. At part throttle, high engine vacuum is used to move a timing plate in the distributor to advance the timing. One of these circumstances is part throttle operation, where lean fuel mixtures slow down the burn. Under different operating conditions, the engine needs more timing advance to run properly. It is far stronger than the pressed steel factory ones that can fatigue and break from high RPM or constant gear drive chatter.On old motors, timing is done mechanically there is no computer to control advance. With the aluminum distributor housing fully seated against the block, verify that the distributor gear can be lifted off the support in the block at least. Timing chain set and camshaft must be removed. #FORD 302 DISTRIBUTOR INSTALLATION INSTALL#The Machined Billet Steel Trigger Cup is machined in one piece from 1020 steel. dISTRIbUTOR GEAR INSTALLATION: After STEP 7, install distributor assembly in the block you are using. The triggering system for your ECU is critical to ensure accurate ignition timing. You must select the correct Cap type for your application before you place your order. 79.95 79.95 79.95 MALLORY UNILITE DISTRIBUTORS Mechanical Advance Chevy V8.
