Looking for opinions on cranks
Winberg
Callies
Bryant
Anything exotic available?
Others

Also oil pan: Jim Johnstone or Dan Olson, other?

My regular stuff has run about 489 HP, my one good one hit 509, shooting for 515 this go round

Thanks for input. After much research I ordered a Bryant crank with special oil option. I want to run minimal oil volume in certain conditions and light weight oil. This crank at least offers some confidence in going that direction.
Still looking at oil pans however.

I am intrigued by Kaase’s comment that if he had to look in only one area only for gains he chose oil pans.

percent wise, you can always make more gains with a small engine. and a good design oil pan on a 265 will prove more % that a bigger cam.
no dyno proof, but my off-the-shelf Moroso kick-out did make a difference in my 265.

In my old ‘56 Chevy 265” Jr Stock, in the late ‘60s, I borrowed a friend’s big lathe. My pistons were from Jere Stahl. Forgedtru, extremely lightened. The first crank I had, the counter weights were drilled everywhere. I decided to lower inertia all I could, and loose all the big holes drilled in the edges of the counterweights. Wanted to clean up those edges, hoping to “streamline” them somewhat. My friend who did my balancing also owned the big lathe I used. Our shops had a door between them. I spent part of a Sunday cutting them down on another crank. Smaller diameter of the counterweights = lower inertia.
I new it would likely need some Mallory (Tungston, right?) to balance it. I had no idea how much. LOL
I was almost 22 years old. Typical twenty something, thought I had everything figured out. LOL Boy, did I get a cussing from my balancing guy! It almost bounced off his balancing machine first time he spun it up.
Lower Inertia is worth something. It was faster. Mallory wasn’t cheap, either. Never had that much in a crank at that time. First weekend out, it was worth it. Thought I had hung the moon.

Jere Stahl also put me onto 5W20 oil.

No “Honda rods” any of us was aware of. I had told my crankshaft guy what I was trying to do, and he said I might also think about smaller crank journals, to lower bearing surface speed & save a little more rotating weight. He put me into .060” under bearings. I had never heard of those. Very thick. LOL

Old guys may remember my machinist, and crankshaft wizard: Roy “Goob” Tuller, who drove “The Freight Train” twin engine Top Gas Dragster, out of California? Not sure how many years he drove it. His crankshafts were almost to pretty to hide in an engine. I had a famous machinist! We all called him Goober.
