HEI distributor cap upgrade(?) worthwhile on stock 350 5.7L?

[Evets]

Greetings,
First Chevy truck, first post, and first time saying "Thank you" for all the information I've already received via lurking.

As part of resurrecting a new-to-me truck that has been sitting/dead for the last 9 months, I'm going to attempt my first tune up in 25 years. My question is this: Is there much (any?) improvement in operation to be had by replacing the stock AC-Delco dist. cap with a Davis Unified Ignition Street/Strip Coil Kit ($79), or something similar, as part of the overall tune up? The 350 5.7L is stock and I have no plans to upgrade cam/manifold/exhaust/etc. at the moment.

Thanks in advance for any advice you can share.
