I'm considering putting an HEI distributor in a stock '67 Cutlass 330.
I have some distributors. I plan to refurbish one for this car.
I'm not sure what engines these came from and which would be best to use in this car.
The part numbers are 1103324 (blue), 1103410 (gold) and 110 3260 (blue).
I'm assuming the blue ones are out of a big block or a 403 small block and the gold one from a small block.
First question: Can anyone help me identify exactly what these came from?
2nd question: which one would have the curve advance that would work best with this engine?
Thanks in advance for any info.

1103324: 1978 Fullsize 403

1103410: 1973 or '74 350 (not sure): probably about 0°@ 1,200 RPM, 4°-6° @ 1,500 RPM, 16°-20° @ 4,400 RPM

1103260: 1977 403, 0° @ 1000 RPM, 13.5° @ 3200 Rpm, Vacuum Advance 0° @ 6"Hg 24° @ 13"Hg



Your original distributor:

1111048: 0°-2° @ 400 RPM, 8°-10° @ 1,025 RPM, 14°-16° @ 2,000 RPM, Vacuum Advance Starts @ 6-8"Hg, 9° @ 15.5-18.5"Hg



May I ask you why, if you have the correct distributor, with the correct advance, you are so concerned about which replacement distributor with the WRONG advance to substitute for it?
