With regards to the oil pump, there is a multi-sided (octagonal??) rod that goes from the bottom of your distributor to drive the oil pump. If you look there's a hole at the bottom of the distributor bore that goes through to the bottom of the block. That's the one I can answer for sure. The other one is a little more complicated. With regards to your MSD distributor, I don't know the "correct" way, but this is how I've always installed distributors, and it's never gone awry (so far). Install your rotor button and cap and mark the spot on the distributor where your number one plug wire is (just a temp chalk mark on the distributor body will do). Remove your #1 spark plug and rotate the motor (preferably by hand/wrench) until the piston is at top dead center. This is the part that's easy to do wrong. If the piston is on the compression stroke, you're good to go. If it's on the exhaust stroke, you are installing the distributor 180 degrees off. While you're rotating the motor to find Top Dead Center, put your finger over the spark plug hole and make sure the cylinder is pushing air out of the plug hole, not letting the compression out of the exhaust valve. DO NOT DO THIS IF YOU ARE BUMPING OVER THE ENGINE WITH THE STARTER!!!! I've seen people injure themselves when the engine is on the intake stroke (sucking) and they stick their finger in the spark plug hole. Not a good idea. At any rate, once you find the top dead center on the compression stroke, take the cap off of your distributor and turn the rotor button until it's aimed directly at the mark you made for the number one spark plug wire. In short this means that when the #1 piston reaches top dead center on the compression stroke, your distributor will fire the number one plug. Hold the rotor in that position and install the distributor. As long as the rotor is pointing at the #1 plug wire, it doesn't matter how you orient the distributor on the drive gear (cam), so just drop it in a position that will allow clearance for adjusting the advance (like if you have a vaccuum advance, don't drop the distributor with the advance stuck against the carburetor or some other obstruction). Make sure your oil pump is installed prior to dropping the distributor, and that the pump drive shaft (from the bottom of the distributor) is in place. The distributor should drop easily into place. If not, pull it back up and turn it a few degrees one way or the other and try it again. You don't want to force it. Once it drops into position (you'll know when it does), you need to install the distributor hold-down clamp, which is like a half-moon shaped piece of metal with a bolt going through it. If this is missing, you can get one anywhere (junkyard or auto parts store). If everything else is together, you're ready to crank her up and adjust the timing. I hope this helps, and good luck!! :Hello, I was on the board a long time ago and recently got back in the swing. Anyways, I'm in the middle of putting an AOD and carbureted 302 in my '75 Mav. This is my first try--half of this stuff I've never seen before. The 302 I'm putting together from "scratch," and I have no other 302 to reference. Any input on the following: Is my oil pan supposed to have a forward or aft sump? Is there anything that actuates my oil pump, or does it just hang there? How do I make sure my MSD distributor is lined up correctly with the cylinder sequence and how do I bolt it on? Anyone in the Bremerton/Seattle area who wants to come help me out? Thanks! |
