This morning I went to the local pull-a-part and cleaned them out of slant six distributors. I got one off of a 76 Aspen wagon, a 73 Valiant sedan, and an early 60s Dodge? b-body sedan (the front clip was gone as were all the badges).
I brought them all home, cleaned them up, and dissected them. Here are the results:
Distributor 1
source: 1976 Aspen wagon- one-barrel, base timing 2 BTDC
distributor tag number: 3874598
Vacuum advance: 8.5R, factory settings vacuum starts at 7, all in by 14
governor: 13R
Springs:
Distributor 2
source: 1973 Valiant sedan- a/c, p/b, one-barrel, base timing ???
Distributor tag number: 3755042
Vacuum advance: 8.5R, factory settings start at 7, all in by 14
governor: 15L
Springs:
The heavy spring is so long it almost touches the body of the distributor, but doesn't.
Distributor 3
source: mystery early 60s mopar sedan, no options, base timing???
Distributor tag number: 2444254
Vacum advance: 6.5X, pod didn't hold a vacuum
Governor: 11.5
springs:
This is a very nice distributor. The springs actually fit over little towers that have a "T" on the end to hold the springs on. Also, the distributor has a cute little oiler on the side for the bearings! How cool is that!
In addition to these distributors, I have the parts I mentioned above (9R governor, various springs, vacuum can that comes in above 10, and a VC-208 vacuum can).
So here's my question: which one of these, or what combination of parts would work best in the motor in my brother's van? Right now I am going to try the stock 76 aspen distributor since the motor in the van is a 76 and since the van weighs about the same as the aspen wagon (roughly 3000 pounds). I will try it with the base timing at 2 and go from there.
However, I am very open to suggestions about what parts to mix and match to get better gas mileage and performance. I also plan on mapping the mechanical advance curve for each of these distributors before i start swapping the guts around. I just need to figure out how to put EI guts into the early 60s points distributor...
Thanks in advance for what I know will be valuable tips.
