In view of the recent discussions on the forum regarding ZDDP, I thought the following information may be of interest. If you go to www.tbirdsbygil.com you will see an underlined link in the fourth sentence to Gils Garage. Click on the link and scroll down to Engines and click on Engine Oils. Great article there on ZDDP for our Y-Blocks. This site is for Gil Baumgartners Classic Thunderbird and Ford Restorations. Many of you know Gil. For those that don't, Gil is the International Authenticity Chairman, Chief Judge and Concours Chairman for the Classic Thunderbird Club International, CTCI. He has done Concours Restorations on many Thunderbirds and Ford cars. He has rebuilt many Y-blocks including some of the few remaining factory super-charged 57 Birds and the one surviving factory 1957 Battlebird. As everyone here also knows, all 55, 56 and 57 Thunderbirds were powered by 292 or 312 Y-Blocks. Gil is also currently performing analysis on oil additives to determine which have the proper amounts of ZDDP for our flat tappet Y-blocks. The results will be available by the first of the year and he will publish them. I would assume the article will also be posted at Gils Garage.

Merry Christmas to all,
