Ditto on what jhv48 posted.
Use standard pulleys. Better at idle and high rpms.
You posted OD pulleys. Over drive?
Also new motor may be a little tight. Put some miles on it and watch the water temp. Keep it under 240 or so. You will be ok.
Make sure
oil sensor is near the bottom of the
oil pan to keep it under the hot
oil. I like to put my oil sensor in the remote oil filter. They make one that has two in and two out ports. I plug one and install the sensor in the other. Works better and give you a truer temperature.
I have found gauges off 8 to 12 degrees. So don't trust the gauge. Buy a Digital Infrared Thermometers. Cost $35 to $220. I get by with the $140 unit. I bought a couple of $40 to $80 units that were junk.
