I am Liking The Redline 30WT 10w30 Racing Oil to try out this Fall in the '76 Pontiac 455 engine.
The Redline 80w140 Gear oil I used in the '63 Pontiac Gp 9.3 Posi Differential dropped oil temps checking touching by hand after several long 100-110 mph runs on the Highways for 10-15 miles nonstop.
Touch the back housing of the Differential and it's just warm to the touch around 105 F.
you need a decent/ acurate infrared temp gun,

yeah its expensive but Ive felt its well worth the cost for as much as I've used it for years...
very helpful in diagnosing various ignition, oil flow and exhaust temp and tuning issues
