Smaller rod journals in LS? Has anyone used smaller rod journals in any LS build? I know this can get expensive, and probably not much return for the money, but it has to help in quick reving, high rpm, N/A applications.

Through lower friction, so I would say increased power throughout the range, though the increase would be minimal.

It's one of those things where you're leaving no stone unturned in your build. I would say if you're porting stock heads and using a hyd roller then you can't justify the expense of smaller journals.
But if you're using state of the art heads and intake along with a llsr, vacuum pump, lightweight drivetrain etc. then I would think this would go on the list to look at.

AL Main Caps = .001" MB Hi All, the "Honda" LS crankshaft IS made for "class racing", one similar application is a "cup" engine specification.
The engine requirements ARE high RPM (9000+) AND LOW BMEP, thus no Turbos/SC/NOS.
The costs do do so is OVER 10,000 USD, the Billet Crankshaft@6K, the Billet Rods@3K, the .750" M-350 DLC pins@1K.
AL Main CAPS with "spacers" ???
I would STATE WHEN an AL billet main cap is fitted, the bearing Clearance MUST BE less than .001".
THEN there is the cost of the heads/valve train, I would fit the Mercury Racing FOUR Valve head conversion.
