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 ^^^^^^^
