Video from Steve Morris doing a bearing inspection/replacement after Cleetus took his El Camino to Midwest Drag Week
Engine is a twin turbo Steve Morris 540 Chevrolet big block running methanol. Made 2,000+ whp on Cleet's dyno. Car runs high-6's @ 200+. This was after Midwest Drag Week, which had about 15 passes and about 800 miles of street driving.
From earlier videos, engine oil is Driven GP-1 20w50 (changed often, maybe every day of the event). Oil temps during street driving were 220+ with the bash plate that protects the oil pan installed. Temps dropped to 200ish with the plate removed. With the high engine oil temp and lighter viscosity (it's mentioned in the video that straight 70 is the usual choice), Steve chose to tighten up the main clearance to gain back some oil pressure. Oil pressure with the hot oil wasn't low enough to hurt anything, but it was low enough that he wanted more for street driving.
