Along with the DDS dry sump oil pump the ARPM dry sump oil pump are some of the originals.

DDS was owned by Dean and Ken Lowry. ARPM was owned by Ken Lowry. I have used both of their pumps in the past. I just bought a CB dry sump pump to install on my 2180 engine while I'm swapping the cam. Other inovations by Ken and Dean were the ARPM case with a dropped cam for 90 mm plus strokers and 96 mm and up cylinders. ARPM cast the original Super Flow heads designed by Dean. Dean was the first to run 9.90 in the 1/4 mile with a Bug. When he passed away he was working on a 150 mph Super Beetle for the Speed runs at the Bonneville Salt Flats.
