June 2021 feedback: A customer reordering a steel 2.8 scraper shared that he found that the scraper reduced his ET in the 1/4 mile by a tenth of a second.  The engine was turning 6000 rpm plus.

60 degree V6 2.8, 3.1, 3.4 -- there are versions of the 2.8 with and without the crank reluctor ring (timing wheel).  This modification is also available for the other strokes.  $94.95



The pictures below show the scraper for the 3.4 with aluminum sump and cross-bolted mains.  The scraper is designed to fit under the factory windage tray as well.
