John,
There are several options for an electronic conversion:
1. Breakerless electronic conversion of original Autolite: invisible,
fits under the cap. The following kits, made by
PerTronix, are available from Royze, Inc. (800-421-2011, www.royze.com
<http://www.royze.com/> ):
CH392 1956 - 58, 12 volt, dual point only, all
Hemi/Poly, 318 A series engines
CH331P6 1951 - 55, 6 volt, dual point only, all
Hemi/Poly engines
CH413 1959 - 72, dual point only, B and RB
series engines only
2. If your distributor is not a dual point, then an interchangeable (same
shaft length) dual point distributor could be installed and converted.
3. A single point distributor could be converted by swapping in the breaker
plate and cam/plate from a dual point (these 2 parts must be dual point
parts to maintain "phasing" relative to the distributor cap). The length of
the slot in the cam/plate controls the total mechanical advance and a
different cam/plate will probably have a different value, affecting total
timing advance. This is useful if you want a "numbers matching" distributor.
4. A 1959 or newer 318/340 single point Mopar distributor will fit a 241/270
Dodge, 277/301/303/318/326 Poly, and can use the PerTronix breakerless
conversion (cheaper than Royze dual point conversion). A 315/325 Dodge and
331/354 and 392 Chryslers need an adapter to extend the shaft. I am not sure
if DeSotos need a shaft adapter. There are no conversions yet for 1958 and
older single point Autolite distributors.
5. Distributor, late model Mopar electronic: The electronic distributor for
any 318/340/360 LA engine will fit into a 241 or 270 Dodge and
277/301/303/318/326 Poly without modification. Mopar Performance kit, P/N
P3690426 (318/340/360 LA), includes distributor, wiring harness, external
control module, ballast resistor, and instructions. This option will not
have a "vintage" appearance.
6. Big block 350/361/383 B and 383/413 RB engines also have similar
PerTronix and Mopar Performance conversions available.

Subject: Re: [FWDLK] Distributor question
Does Petronix or anyone else make an electronic ignition for a '57 Fury dual
point distributor? I haven't been able to find one. Thanks in advance.
