question on ignition coils
Anyone have a recommendation on an ignition coil? Placing an order with summit today & figured I'd order a coil while I'm at it. Never thought there would be so many choices/specs. Coil windings, primary & secondary resistance, inductance, 
. Does it matter much? I plan to fire the engine with the points installed and then install the " Breakerless SE " electronic conversion shortly thereafter.

I'm running a Summit CD igintion w/rev limiter, and a plain old GM coil. I got the Summit branded box 'cause it was cheaper than the rest. and according to them, it's made by Mallory- and the instuction sheets ARE identical

Figured it was made by one of the major manufacturers anyway.
Thanks

I'm an electrical engineer, so I'm perhaps a bit more finicky in this area, and prefer to do the calculations if the individual part specs are available. BUT, real world "field" data sure seems to show that most engines will run reasonably well even when the parts are picked out in a somewhat blindfolded fashion (ie: relying on marketing hype).

If it were me I would use your stock coil until you change over to the breakerless dist. and then I would use one of mallory's electronic coils or the msd blaster 2. They seem to work better with electronic distributors. Both are 1.0 to 0.8 ohm coils. Your points type coil is probably a 3.0 ohm coil. Check it & see.

I would use the stock one for the initial start-up if I had it. Bought the car as a project and it was amongst the missing. Figured I stick with a plain black coil rather than chrome. Not to much chrome going on the engine
Thanks for the tips

There's a lot of hype about coils. A coil will put out whatever voltage is necessary up to the maximum capability of the coil itself. As long as your ignition system is in good shape, a stock coil should provide whatever voltage is necessary. A performance coil would be able to provide additional voltage if necessary, but again, if everything is in good shape, the performance coil will do no different than the stock....that and give you a decal to tell everyone what coil you have.
Stick with the stock system until you're ready to do an upgrade...then get a system of all integrated and matched components. You'll get better results that way.
