Follow your Owner's Manual.... 5W-30, with 10W-30 being acceptable if temperature will not go below 0degF.
You must get a thermostat made specifically for an LT1 reverse flow cooling system. I know Hypertech makes one for about $20. Most auto parts store will not know the correct part, and will try and sell you a generic t'stat for a small block Chevy. That will not work correctly.

Got the Hypertech 160* powerstat in mine for many years and works great. Still get enough heat in the winter and barely goes over 185* even on a hot summer day with the AC running.
To take full advantage of the 160* I strongly recommend you reprogram the fans either with Hypertech PP+ or PPIII, or in a custom tune. There might even be a low temp switch for your model year, not sure.Comment
