Ok. Didnt know that. Filter is in stock location. -8 lines as Derale suggested. Would that be a problem? If it's running bypass oil to the cooler -8 is probably ok. If it's the main feed from the pump to the engine you're lucky it hasn't spun all the rods out of it. My builder does a pile of go fast marine engines with remote filters and he won't run less than -16 on those. He had a customer come to him with a pair of 540 BBC from another builder. 1 blew up and the other mortally wounded. This was after blowing up a fresh pair before. Cranks burnt right out of them. -12 hydraulic hose to and from the remote filters. -12 hydraulic is a good bit less than 3/4". New engines plumbed with -16 Russell and no more blue crankshafts. At $30K a pop, that was lesson hard learned. Kevin

I had mentioned in Daves previous thread that I am running -12 and that I had ported out the sandwich plate for extra flow. I think -8 is too small.

Do you run an external feed ? What size is your pick up feed line ? Would anyone run a single -8 external feed line ? I dont think so.

Wow, those look huge. My pick up is the standard 3/8 tube. Measured the -8 fittings and hose, 3/8". I thought -8 was 1/2"? The oil filter fitting measures 1/2". I idea was -8 was 1/2" dia and oil filter fitting 1?2", no need to go bigger. If i go -12 will i need to drill and tap oil filter sandwich adaptor for the bigger fittings? 6 an= 3/8 8 an= 1/2 10 an= 5/8

Those must be the thread sizes because i just measured the -8 orifice and it meadures 3/8". What is the orifice size of the standard BB pick up tube? I dont understand why i would need bigger cooler hose and fittings than the pick up tube. Length of the hoses makes a difference. And a 3/8 pickup is barely at the minimum. Think about a dry sump. Look how big the inlets to the pump are.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Gonna step it up to a -10. I dont see the need for any thing larger since the oil filter adaptor is 1/2" and the pick up tube is 3/8". How would using larger hose on the cooler improve any flow when the pick up is smaller? Can only get so much oil thru that 3/8" pick up. _10 is .530" id. Should be more than enough. I would like to hear from anyone that had a failure using anything smaller than -12 hose on their cooler system. At one time I had a Jaguar XJ6 and the oil cooler lines where in the range of one inch or so and I'd bet money the pickup in the pan didn't come close to that. There's also gonna be a parasitic loss pushing oil down those smaller lines.
Have a great day Iowan
