Thanks for the videos Matt. Boats, irrigation pumps, sirens, saw mills, generators etc were all common homes for the 331 and 354 Hemis. As far as I know they never used the bigger 392s in industrial applications although I have heard rumors that some of the 392s did find their way into boat (marine applications).

The neatest application for an Industrial HEMI I think I ever came across was in an old Airport tug that was for sale on E Bay a few years ago.......now that would have been FUN.

They apparently sold enough industrial and marine motors to justify stamping out their own valve covers besides the more common Fire Power and Imperial passenger car covers.

The bumps between the spark plug holes on the Industrial and Marine valve covers were for clearance for adjustable rocker arms which were kind of rareto find on the first generation Hemis as mos of them came with hydraulic lifters and non-adjustable rockers. I;ve never had a marine hemi apart, but I've been around the Industrial Hemis, and even though the valve covers have the clearance bumps I've yet to find one that actually had solid lifters and adjustable rockers.

The (Non-Bump) Fire Power, Industrial and Marine Valve Covers are all pretty common. The non marked, and Fire Power Covers WITH adjustable rockers bumps (not shown but used on Chrysler 331, 354 and 392 letter series cars which did have solid cams and adjustable rockers) are probably the rarest and bring some really good money if you came across a set. Or at least they did until they started reproducing them in China.
