Trailbeast HEI System-Looking for one....

I recently chatted with Greg (Trailbeast) and found out that he doesn’t build his HEI systems’ anymore. He said the 4secondsflat system is good, but I don’t need a system like that. I have a stock 73 Swinger and just wanted to upgrade the ignition a bit. I was wondering if someone bought one of his systems and now can’t use it because their build took another direction and they now need a more performance oriented system. Any help would be appreciated.
Thanks,
