T Bs kit just makes for a nice appreance you also get rid of coil wires, Yes you can buy parts at local auto parts but till you get them and do your own wiring and splicing its better to go with tb"s plus if you need assistance hes there for you.
I'm not frightened by wiring and splices, just hadn't seen any wiring diagrams on how to make it all work, or what all parts were required, and I was soliciting opinions.
I did some more searching and saw a couple folks who commented that the factory HEI module suffered similar issues as the factory Mopar ignition at 4500rpm+. I have yet to experience such phenomenon on mine, but I also spent a couple extra $ when converting the car to electronic a couple years ago and bought the orange box, and mine doesn't see the high side of 4500 very often.
I'll likely wind up with an MSD or Mallory type setup in the long run with the planned big block, but if the HEI is a better ignition setup with results I can quantify, then I'll look into it as an interim improvement. But, at $140 for the complete kit from classichei.com, I'm not too far away from an aftermarket ignition with rev limiter, hence the reason I thought about the revonator...factory appearance/compatibility, with better energy and rev limiter.
