Re: 288 with hydraulic lifters

If we are talking 22nd series 288/327 E means a late design camshaft and 7 quart oil pan instead of a 6 quart pan. It may also apply to 23rd series.

There were other combinations that also included different pistons and rings also with a 7 quart pan and with or without the different camshaft.

Check out this service counselor page 47 article for various suffix combos used on 22nd series.https://www.packardinfo.com/xoops/html/downloads/SC/SC-VOL22NO12.pdf The suffixes varied over the years and did not necessarily mean the same thing one year to the next. Best I can determine no complete compilation of all of them has been made. Some but not all have been detailed in various letter, counselor, and bulletin articles. To add to the confusion they also used symbols such as stars and hash marks as prefix or suffixes or dabs of paint on an item to indicate something was different from originally equipped or spec'd.
