Bob - great looking '54.  Amazing - some years ago unless it was a woodie, nobody would look at a station wagon.  Now they're popping up slowly but surely and they look good!

I'm sorry, I forgot to thank jd2ksilver for his response to my question. We drove the car 206 miles yesterday on a road trip to see the Lost River in Orange County,  Indiana. River disappears for 22 miles into underground caverns, before resurfacing at the Orangeville Rise. Car behaved well; got 16MPG with overdrive. But, it is not as much fun to drive as the P-15. Bob

Jim, Thaks for your research. Bob

Bob - sorry for the delay in answering but I've spent two days putting up with people jammed in a shopping mall!  Merry Christmas to all!

Anyway, its a 230 cubic inch.  You should find what looks like a vertical diamond in front of the number.  Its a late '54 engine but serial number definately tells its a 230.....

Jim, P-25 432141 is the number. Thanks, Bob

Bob - what is the serial number on the engine block? (left front corner of the block, below the cylinder head, just above the generator mounting).  If there is a number there, I can I.D. the size of the engine for you.  If the serial number spot is blank, then it was a factory new engine sold aftermarket.  These engines had a tag riveted to the block to I.D. it but these tags were light duty brass and soon disappeared.  Jim Benjaminson

Not sure if this will work or not, but here goes,

Others will have more info I am sure, but it is my understanding it is used to find top dead center of the piston for timing purposes. 

Waht is the purpose of the plug in the head over cylinder #6? Is it a passage into the cylinder? Is the hole separated from the coolant? I am trying to find out if I have a 230 P-25 by measuring the stroke. The plug has been removed, but the hole is crusted shut. I want to be sure that a I can punch through without damage. Bob
