Screw it..

It's so common knowledge I reckon its useless.

Typical for manufacturers to up date parts.

The MoPar parts books show those changes.

Just forget it. I'll delete the ****.  It's so common knowledge it's not interesting.

I though it was helpful. Not all of us have a library full of reference books, and thus far the internet only has so much love for the ol' flatties. Maybe someone could bless us with a few scanned pages or a link.

 

I was looking at the horsepower ratings for the Dodge lineup and found it interesting that the rated power output and compression didn't change from 1947-1953. Plymouth was bumping it up every couple years, with '53 going up to 7.1/100hp, only 3 HP less than its big brother. I wouldn't think a cam change, even a small one would yield some sort of gain, unless Dodge just didn't bother to re-rate the engine.

'54 did jump up, both in output and compression. 

So, this all leaves me wondering if the 230s ran a larger cam to help fill those extra 12"?

From what I had in my D24 and the present cam from a D46 the lobes on the D46 cam were taller.   Couldn't find either # in the Parts Book for my D24 or the 46-56 Hollander.

casting number are not part numbers.....little data was tracked in this manner....a cast profile can be ground to many different cam profiles in duration and lift.
