I have a wierd Ignition problem (460)
It's a 77. I put a new cam from Summit racing.
I used a timing gear from a 69 lincoln.
I freshend this engine. All new stuff, rings valves etc etc.
It's running, but I cant get the Dist. to rotate into the right place.
It's either a little too far advanced, or I cant get it to advance far enough!
I've tried moving the Dist. a tooth either way, and shifting the wires around.
The Dist. crashes into the Thermostat housing, going one direction, and into the AC Brackets the other direction.
I should be able to get that dist. down in there, with plenty of movment either side of 10 Degrees advanced.
Anybody else have a problem like this?

Pull the distributor and static time it according to the manual at TDC.
You are probably moving the dizzy two notches. I know it is frustrating but it is just a matter of dropping the dist into the right tooth. Remember the dist rotates as it is inserted or removed. I have done it so many times over the years that I can drop one right in on target every time, with the pump shaft lined up. But that took a little practice and eyeball calibration b4 that happened.

Sounds like you got the distributor a tooth off. Take out the number 1 cylindar spark plug and put a rag in the cylindar and turn the engine over till the rag pops out of the spark plug hole. Take the distrbitor out and take the cap off and turn the distributor so the rotor is pointing at number 1. Put the distributor back in the engine and put the cap on. You should now be at tdc on number 1 power stroke. Good Luck!

Sounds to me like his only problem is his thinks the vacuum advance has to be in a certain spot when he drops the dissy in.
Just keep the *rotor pointing the right direction* and turn the dissy back counter-clockwise (so you can tunrn it later)before dropping the dissy back down the hole.

Torque1st may have the answer too. I'll tell y'all whatever it is, if I find it.
The Dist. will drop in OK. The problem is the place the Vacuum Advance has to fit is very limited.
I've never had a Dist. that would drop in one tooth fast, or one tooth slow, but not right on. (I dont want to think this Cam I bought is mis-aligned, or the 69 Lincoln timing gear is not going to work on this cam)
I have moved this one twice.
One way, it's timed so fast, that I can barely get it started, and the Vacuum Advance hits the T-stat housing when I try to bring it back to 10 Degrees advance.
The other way it's so slow, I cant turn the Dist. far enough to reach the 10 Degree advance I want. The Vacuum Advance is stopped by the AC Bracket at about 4/6 degrees advanced.
A friend suggested looking up into the Vacuum advance. Some of them have an Allen screw up in there, which can adjust the home position of the Vacuum advance plunger, and thus alter the timing by a few degrees. (I wonder if somebody has already done that to me?)
That may work. I'll know in a couple of days.
Only a nut like me would work this hard to get a Gas Guzzler going when we are going in to Fuel Crisis.

Thudpucker, are you sure youre only moving the shaft one tooth when you reposition? It sounds like you are probably skipping two teeth, most likely because of the position of the oil pump drive shaft. The dizzy shaft will spline on the oil pump shaft every 2nd tooth.
Either that or you got an oversize vaccuum advance canister.....

Thanks Mudder, Eric suggested that too.
It's entirely possible I did go two teeth one way and two teeth back.
I've been fiddeling with this stuff for a long time, but it's always possible.......As I said, I'll know in a day or so. And I'll fess up if it turns out to be a 'Self inflicted wound', I'll let you know what it is.

Thudpucker, I agree with the concensus(sp) of going two teeth. I've run into the same problem dropping in the dizzy on my 429CJ. What I did was I took a deep socket on a speed wrench that fit the drive shaft and turned it ccw a little more than 1/12 of a turn (just over 1/2 of a flat). That let me drop it in on the tooth I wanted.
Also, on the vacuum advance, if the adjustment screw is accessed thru' the nipple the vacuum hose hooks to, I think that adjusts the spring rate or the ending position (limit) but doesn't change the home position. Of course, your mileage may vary.
Just my 2¢,
Greg
