My questions are: 1 - Who is the Manufacture and what is the part number for the original oil cooler for BOTH the O-320 and O-360 engines? 2 - Who is the Manufacture and what is the part number for the Upgrade oil cooler for BOTH the O-320 and O-360 engines? 3 - Am I correct in that that the upgrade increases the number of vanes from 5 to 6? 4 - Are there any issues in fitting the upgrade cooler into the location of the original? 5 - What kind of improvement can be expected, are there any numbers available? 6 - I have seen on many installation that a reducer is used on the oil cooler to reduce the thread size from 3/8" NPT to 1/4" NPT is there any reason WHY ALL the associated hosing and fittings are not 3/8" NPT? 6a - I ask the above question because when looking at some data I have found on the Internet it would only seem logical to collect the data with the least amount of restriction to the cooler. What are your thoughts? Thanks for being there Gang and thanks for the help. Barry "Chop'd Liver"
