I recently ordered the Mocal Sandwich T-stat adaptors and when they arrived, I found that the gasket/housing diameter are smaller than that of the motor. Sandwich O-ring diameter = 2 - 5/8", Block O-ring diameter = 3 - 3/8"
How do you get the mocal unit to work with the 502 Gen 6 block?
Has anybody used Earl's units for Gen 6?

Tables from ANSI for 3/8" diameter pipe:
@40psi = 12 SCFM Flow rate
@60psi = 18 SCFM Flow rate
Tables from ANSI for 7/16" diameter pipe:
@40psi = 17 SCFM Flow rate
@60psi = 25 SCFM Flow rate
From the tables above, there is plenty of flow even for 3/8".
To set the record straight, it is the core size of the cooler that seems to be the limiting factor for heat transfer on the stock equipment.
PatriYacht: Thanks for the offer of the cooler. I'll let you know once I figure this thing out.

I spoke with the engineer that designed the plates and he indicated that internal flow capacity of the plates were the same between the high flow and the standard one. The difference is the ability to use the 16AN rather than 12AN. Using the plate I have eliminated a bunch of fittings which is where your major restrictions in the system are. I only have 4 fittings and abut 3 feet of hose. Much less restriction than the stock setup. That is 6 less fitting than stock with t-stat. Figure the fittings are about 25 a pop and and hose 4 bucks a foot. I think the remote t-stat with remote filter had about 10 feet of hose.
Stock setup with oil t-stat added;
fitting out of block adapter, fitting into oil t-stat, fitting out of oil t-stat, fitting into cooler, fitting out of cooler, fitting into t-stat, fitting out of t-stat, fitting into remote oil filter adapter, fitting out of remote adapter, fitting into block adapter and a bunch of hose. The fittings are always smaller ID that the hose and I believe that is where most of your flow problems come into play. By using the SP1CT I have a total of four 45's of 12AN and only three feet of hose. In addition I dressed the SP1CT with a Dremel tool for added flow. Produced casting left a little to be desired.
By the way the High Flow model was designed specifically for Illmore V-10.
The SP1CT will accept a K&N HP2003 filter.

Under stated if the casting looked anything like mine. I was not very pleased when I got it but once I cleaned it up I was happy. Seems like mocal could spend another 15mins to clean up a nice piece.

Badog,I eliminated a mile of hose,fittings and adaters too when I redesigned my oil system. My stock cooler was mounted on the opposite side of the motor so there was about 15 feet of hose running back and forth. I went from factory fittings and hose that was around 7/16 id with some fittings as small as .390 id to -12 full flow fittings that had a minumum is of .550. I also used only about 5 feet of hose and 6 fitiings total to go from block adapter to filter to cooler and back. When I first did this on my old 502 I picked up 15-20 psi of oil pressure,the block bypass valves must have been open all the time,Smitty
