You aren't wrong.
I do two distinctly different conversions,
HEI with remote module for stock cast iron W dists, MSD trigger for same, uses a stock W dist, so, not higher than stock
Next, small/big block aluminum dist with attached adapters for fit to W engines, HEI with module mounted on dist body, or MSD trigger only. This dist is about 1-1/8th inches higher overall than a W dist is.
Can do same for Mallory, real, live HEI or MSD trigger only.
Not an ad, they aren't allowed on this part of the site, just FYI.
