Re: [Chrysler300] 1957 Chrysler Windsor W/354 Poly Engine

Larry go with rtv on lower half of valve cover gasket . The oil pools around the exhaust valve spring on poly , at those “dips”  starts to leak , nuts may bottom due to a deformed cover . Put two washers under nut , torque to 30 inch pounds . Save yourself a lot of hassle . As in smoking exhaust manifolds , oil loss at back of engine .

My money is going to go on silver for the whole 354 engine including valve covers - as in the same silver we have on the hemi-head  392 (except for its gold valve covers). Here is a link to a '58 Windsor that looks like it may be fairly original under the hood:

It could even be that since Chrysler put this engine in the lower priced cars as a money saving gesture, they may have shot the whole engine in silver after it was fully assembled - even with the valve covers already installed. I have seen some photos of the Poly/Spitfire engine where the the "Spitfire" name is in red on the valve covers, but I think that may be an incorrect owner enhancement.

For a far more durable (yet color-correct) paint job on your engine that will stay looking new for many years and miles, use the base/clear silver two-stage coatings as on the mid-eighties BMW body paint. Just knock down the gloss on the final clear to maybe a 20 sheen or so with a bit of flatting agent, to duplicate Chrysler's low gloss look of their single-stage silver paint job on the engine.

Hi guys,

My name is Larry Casey and I'm a new member with the 300 club.  I'm from the warm state of Minnesota and a proud owner of a 1958 Chrysler 300D.  The one thing of gathered from this site is there is a great deal of knowledgeable individuals out there concerning these wonderful cars. But today, I have a question, not about my 300D, but my 1957 Chrysler Windsor with a 354 poly engine. I'm having the engine rebuilt, which is almost completed and would like to get the engine painted in the next few days.  I have gone over the internet but have not been able to determine what color this engine was when it came off the line.  Anyone have any info.

Very happy to be member of this club!!!
