Ignition Coil Recommendations

[7Dcuda]

What coil would the experts recommend I run with the MOPAR Performance Distributor and the MOPAR Chrome Ignition Box.

I have the same question only using the Mopar Performance MSD box.  Sorry to hijack your thread.

I hear so many saying or thinking that if they get a stronger coil they'll make more performance. The real facts are that the spark plug gap, the octane level, the spark plug wires, and the amount of compression are the deciding factors. Because what happens is the 4 factors together will create voltage drop at the spark plug right at peak compression before firing. So for example: You run a 50K coil with 10:5 to 1 compression. In actuallity, the spark might see 35K at ignition (for example).

What I used to do is put my engine on the scope. Then I could see what the voltage output was at. After doing that, I was able to determine if I could improve voltage at the spark plug by changing any of the items mentioned above.

I have been using either high output Pertronic coil or the MSD Blaster vibration coil , they put out about 45k v

can those coils be mounted horizontally?  someone told me not every coil can lay on its side.

I run an MSD High Vibration Coil on the 440, mounted horizontally. The PDF file above says,

The Blaster Coil is designed to mount in most factory canister coil mounts. MSD also offers a Chrome
Coil Bracket, PN 8213. It is recommended to mount the PN 8202 and 8223 coils in an upright position.
The High Vibration Coil, PN 8222, can be mounted in any position due to its epoxy potting compound.

so you're good to go with the 8222.

The coil needs to be matched to the ECU box, if a coil puts out for example 100k volts but the motor only needs 35k volts then the coil will only supply 35k volts, electricity is lazy. You need to be aware of the AMP draw also, if the coil requires more than the ECU box then the box will fail.

I use a stock, epoxy-filled coil from the later Chrysler 2.2/2.5L engines. It gives the required spark, vibration resistance, and low price all in one package. Its only drawback is a non-stock appearance. I was steered towards this coil by a speedway motorcycle racer, who said that all the racers used them, due to their high output and resistance to vibration (anybody here who knows these monsters can relate). He said that the parts supposedly designed for the task weren't as tough as that coil, and it had a low failure rate. I bought one with bracket and connector (weatherpack) from a junkyard, and haven't looked back. If looking "correct" is important, use the MSD; if you want the power without the cost, use the little stocker.
