  1. Set aside the value difference of open cars as antiques.  We all understand this.

     

    But as a car to drive, if you don't put the roof down, a closed car is superior - lighter (convertibles require frame reinforcement), cheaper, more weather tight, quieter, no need to replace top periodically.  I've had 5 as daily drivers because I like the experience (We can peacefully differ), which is different from sunroof and windows/side curtains open, enough to put up with these disadvantages.  

  2. To put into perspective, the 1940 Packard 356 was 160 HP.  The all new 1949 Cadillac OHV V8 was 160 HP.  The move to the 327/359 gave Packard a simpler, cheaper to manufacture engine with parts shared with the Juniors, with competitive but no longer leading performance.  

     

    Putting a 288 head on a 327 increases the compression too.  The bores are the same.

    Bryan, I agree that the 70% is no more than a ROT (Rule of Thumb).  Known high-RPM engines (Jag for example) may be able to sustain cruising at higher speeds.  My ROT is for the L-head and T-head engines I have.  I further agree that an OD is the best investment for the OP, who should also either acquire an OD (shorter) driveshaft for the conversion, or have one made up (not expensive).  And replace the u-joints on general principles while the driveshaft is out!

    Agree - the typical flathead or early OHV has a long stroke and relatively heavy pistons and is designed for torque at low rpm.  So conservative rpm limit.  

    That Stude six was already an old design by 1953, really like prewar level.  I had a 41 Plymouth long ago with a similar engine and power/weight, and it wasn't much happy above 50-55 mph although capable of more.

    Thanks Steve.   I think it is an interesting alternative to the 53/54 Caribbean which is around the same ballpark for one as nice as this. 

    Interesting comparisons.  The 22nd Custom is a premium car in every way, but with styling not all like. I really like the optional leather and cord interior vs the full leather. The 53 Caribbean is great looking, but has a more plebeian drivetrain.  The 54 gets a premium engine again, but the styling has always struck me as incrementally upgraded over the regular convertible, less custom.

  5. Your calculation of RPM and speed is rigorous, but the 70% is a bit of a ballpark number at best.  Stroke/piston speed/reciprocating mass are going to effect this.

    I agree 3000 rpm is a reasonable guess.  Keep in mind that when new the car may have been typically driven faster, but expected engine life before rebuild was less also.

    Since Studebaker offered an OD, it's the best speed increase option.  

     

    (And since "three on the tree" covers the late 30's until at least the 1960's, it is indeed irrelevant)

     

  6. No, the 359 is a 1954 engine derived from the 288/327.  The Custom Eight has the 356 (Used 1940-1950).

     

    OK if you like the wires, but they were not available until later.  The original set up was steel wheels, hubcaps with cloisonne badges, and rear fender skirts with the two stainless strips to continue the line of the bumper ridges from front to back.

     

    The convertibles and fastbacks integrate the width change between the doors and greenhouse, caused by using the Clipper main stampings, better than the sedans.

    That's hexavalent chrome. You don't get that at most electroplaters anymore. Trivalent chrome is what most of them do today. It is often more neutral or even a little yellow. You can still get hexavalent chrome done, but only at a few shops and it is disappearing fast.

     

    what you say about hexavalent being rarely used is true, but the electroplated layer deposited is chrome, valence zero, in either case.  The +3 and +6 valence states are the ions in solution.
