AMC 304 distributor drive gear replacement

Ever notice how one repair / upgrade leads to another? While replacing my distributor last weekend, I noticed that the distributor drive gear appeared to be mangled beyond recognition, so ... Now, I'm open to any suggestions as to other logical repairs while I'm in there. I already plan to install the Edelbrock True Double Roller timing set per TeamRush's suggestion (thanks, TR). The water pump is only 6 mo. old, so it should remain good to go. Somewhat unrelated, but I also have a new fuel pump that I'll probably put in while everything is accessible. Anything else? What gaskets will I need other than timing cover & water pump? Any special tools beyond basic hand tools? I've never done anything like this before, so if there's any Charlotte, NC area gearheads up for a wrenching party, I'll supply the beverages of choice! As usual, thanks for your input.

Re: AMC 304 distributor drive gear replacement

Oh yes also replace the gear on the camshaft that runs the distributor. My friends 304 in his cj5 gave out. We were told that those gears wear together and like a lifter and cam, if you replace one you should replace the other. BTW we are still waiting for the gear for the distributor from msd. It's been 2 months and we should get it on the 27th. Also the other thing we were told is to make sure the oil hole in the timing chain gear that goes to the camshaft lines up with the one on the camshaft. You can find a replacement gear from Good luck.

Re: AMC 304 distributor drive gear replacement

Ya I`ll toss my 2 bits in here . Do the AMC oiling upgrade while you have the timing cover off . They lack a lot of oil on the timing set , just drill and tap the left gallery plug behind the timing chain and thread a .023 mig tip in there pointing towards the timing chain . Works great . I did the same thing on TR`s recomendation when I rebuilt my 304 . There are other AMC V8 oiling upgrades but I figured mine being a mostly low reving application , I would leave it at that stage . If ya need the tap / thread size , just email me

Darkskz is completely right about replacing both dist. drive gears . VERY important !
