What heads intake and rotating goodies are you running in your 540? Seems to be quite a few people on the fence about running the 15w50 in our 468 BBC I have to admit I am too since we haven't had any issues with the Brad Penn, save for the price. The new 540 will have a swap meet Callies Magnum crank, Oliver Max rods, JE pistons, and Dart 345 as cast heads with some bowl work, intake is an Edelbrock 454R topped off with a Pro Systems Dominator, cam is a Comp Nitrous grind spun by a belt. Block is an old GM Bowtie block. I'm surprised to hear that you're running a 30wt in your 540. We run pretty loose piston to wall as well as rod and main clearances so the 50wt keeps the oil pressure up.
