Complete HEI Kits for Sale

The coils in the pictures are different. Do you have yo buy anything to go with this kit? Or is it a complete bolt on, and the only part needed is a distributor?

I'd say it's a complete bolt on except if you crimped the connections, as I set it up to be soldered with heat shrink tubing cover.
The must have stuff is there for true HEI, but there are all kinds of upgrades that can be added to compliment it.
These would be Echlin part #MO-3000 long tip rotor.
8.5mm silicone magnacor plug wires.
A relay feed for 12+ instead of factory wiring.

and a few others like different distr caps.

The system work great on it's own, and the other stuff would be upgrades.
