While many people successfully swap in HEI distributors into 1972 Corvettes, it's not a completely straightforward, plug-and-play installation. You'll likely need an HEI distributor specifically designed to fit a small-block Chevy (most likely what your '72 Corvette has), but you might need to do some minor adjustments or modifications, such as:
* Mechanical Advance: The mechanical advance curve on the HEI might need adjustment to match your engine's needs.
* Vacuum Advance: You might need to adapt or replace the vacuum advance mechanism.
* Wiring: The wiring harness will need to be adapted to accommodate the HEI's different wiring configuration. This is generally considered the easiest part, but you need to understand the wiring to avoid problems.
* Distributor Shaft Length: Ensure the shaft length is correct for your engine.
In short: While an HEI *can* fit, it's not guaranteed to be a simple swap. Research is crucial. You'll need to determine the specifics of your engine (small-block or big-block) and find an HEI distributor specifically designed for it. Consult forums and resources dedicated to classic Corvette restoration for guidance and specific recommendations.
