The oil cooler is now installed. Bought a Derale 25 plate cooler and mounted it to the radiator. Primed the oil before i started it up and i could see i lost about 10psi oil pressure with the cooler in the system now and cold oil. Now at 70psi instead of the usual 80 on start up. Took it for a spin and oil temp never went above 200 on this 82* day. Coolant temp did go up a little higher thou at 200* in town cruising. With the cooler oil temp pressure not really an issue yet as it holds viscosity better now.

I built the motor. Best Machine is who suggested to fill the block instead of sleeving it. As for the cooler, Derale said it would not raise my coolant temp if it was mounted tight to radiator. 5* hotter is not bad i dont think. Most of the new stuff now runs 210-215*. Not gonna sweat it just yet. While the dist was out i recurved again. 1 stiffest and a blue spring. A large bushing from Don@FBO with only 6* advance. Set timing at 29* and all in at 34*. I know its not right, buts runs stronger and sounds way happier.

My old pump gas 400 block had four sleeves in it, two due to pitting, 1 and 7, and the other two, #4 and 6, due to block deck surface damage from a blown head gasket No block filler I have seen a really bad 400 block casting split a cylinder wall on the cam side on the dyno also I have learn to start with a good block casting or don't start until you can

Running hotter is probably because you have less timing now.

I thought too much timing would make them run hotter? Had a 69 Roadrunner i tuned up for a guy about 35yrs ago. The 383 in it always ran hot after i gave it a super tune which was a dist dissemble,cleaning and a good recurve with the lightest springs i could find installed, cranking timing up and a carb rebuild. Ran great,but always ran hot. Never figured it out and yrs later i start hearing about too much timing causing an over heat issue. Figured thats what it was.

Its seems to me if i had a restriction i would have more oil pressure not less. I"v seen this before when others had added an oil cooler. Lost pressure. That's because the restriction of the cooler and it's assorted plumbing and adapter is upstream from your gauge port. That's why it shows less pressure. Is your filter remote mounted too? All that extra plumbing causes restriction and most people undersize it to boot. Kevin

I think to much or to little timing can cause extra heat to be ade in the motor, the sweet spot is the best Test, test and test until you find it. Don't assume what yours is with YOUR timing light on YOUR motor is the same (identical to within 1/2 degree) as every one else's This ^^^^^^^

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

Dave this engine is a 500 +- stroker yeah ? If so Im not sure you should be using a 3/8 pick up.

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
