Making a coil pack for earlier sall block?

[clutchdust]

A neighbor happened to be cleaning out his garage and gave me coil packs off some GM engine he worked on. Now I'm wondering if it would make sense to put them on an earlier engine and fire each cylinder off a dedicated coil, like the new LS motors do. I'm thinking it shouldn't be all that hard to use the factory distributor as a trigger to signal the coils when to fire. Any body ever done this? Seems like an MSD box triggering individual coils should really be able to light some shit up.

Haven't done that - but sounds very do-able. I have an Electromotive Distrubitorless System I am putting on with a crank trigger - that will be similar. You could check out this install pdf:

and maybe get a hint or two.
Sounds like a neat project!

I think it would be more trouble than it's worth.

I agree.....:crutches:

Is that coil pack one that has 2 terminals on each pack? GM used a "waste spark" thing that fired 2 plugs at a time- one on a cylinder at TDC (or close) and the other on on the exhaust stroke. To get that to work, you'd have to isolate the terminals so only one would fire, or work out the cam timing and firing order so the events happened at the right time(s).
Lots more hassle than benefits IMHO.

I was thinking of going crank trigger, just for the cool factor, being first kid on MY block and all, but looks as if I sticking with the old HEI as it works....

What drives the oil pump after the distributor is removed?

There is a shaft (part of the kit components) that is inserted where the dizzy was. Or, be redundantly redundant and just leave the Dizzy in place.

Thanks! That would sure clean up the back of the engine.

Yeah - I'lll need the space on mine for the exhaust tubing (SNAKES!) to pass over. I'm modifying a 360 degree setup from Stahl. The under- engine won't work - rack and pinion and oil pan are in the way.
