Crank Pin Hole & Oil Hole Hi All, my cranks do NOT like an "offset" grind.
The forging was designed (same forging as Callies, Scat) with BALANCE Holes in the "pin" area.
Then you need to RESPECT the Oil Hole as it could "move" depending on what side the metal was removed.
I use Marine Crankshaft for the ALM crankshaft AND David is within ONE mile of my shop.

Also the "honda" 6.125 rods that are sometimes used, though not as often as you seem to think, are a 1.88" They arent avail in an 1.85".
You are obviously thinking about merely turning a journal down not offset grinding.
Im sure we know that you dont like kcs from previous posts, but when you try to "throw shade" at him and even his crank grinder without knowing what offset grinding means, it really doesnt help.
Sending me a nasty pm on top for pointing it out shows even less class.
The other part....still not doable esp on a stock crank or non sj crank. The oil holes move ALOT And it does indeed weaken the crank. Depending on the pin geometry it could take quite a bit more off the inside and very little off the outside. It depends on what offset you are looking for. Without extra welding its a recipe for disaster and after all that extra work and cost where are you?
4.8 stroke cranks have std large pins and are commonly used as "short stroke cranks" and are hardly ever turned into a small journal even let alone a Honda journal. 3.622 cranks same way.

Was only using 1.850 as an example of small journal, not a size that a journal should be reduced to. In an effort to gain stroke.

It's "whatmwe"; "What we" with an "m" put in the middle when you miss the space bar and hit "m" instead. "Do not pretend to know what we do and do not sell....."
Plus it took you almost 5 hours to come up with such a nugget of wisdom. Nobody thinks what you say is cute OR funny. So quit being such an ***.

Im sure its not. Esp for use on a stock crank. You are talking about race builds that are beyond what 99% of this whole forum does. As far as using rods for LS its sbc, sj sbc, honda. You dont know that it appears, so why are you on an LS forum arguing any of this? Throwing insults at everyone. It clearly doesnt help your cause.
I do make grammatical errors mostly because i use my phone. Big. Deal.

Stocl cranks are 3.622. 3.625 are usually aftermarket forged. You can assume that but usually even aftermarket setups will stick out of the hole. That is why i said assemble and measure first, then cut the deck. At zero deck youd want .040 min for head gasket to account for thermal expansion and any stretch at the higher rpms.
We have cometic in a 4.185 bore that will fit reg 4 bolt ls or 6 bolt lsx block ans what you are looking for. we have em in .035 .040 and .045 and above of course.

Deck Height = 9.2125 for "0" Hi Last1, your math 1.8125 + 6.350 + 1.050 = 9.2125 for a "0" deck.
My method would be to "deck" your block AND use a 19170419.
I have had problems with those "thin" gaskets. ( NOT LS BUT Cometic .018" with a Subaru 4.00" bore EJ-27)
This problem is caused by the "lack" of metal distance (.01???) and the use of Studs that do not stretch at the AL head's expansion rate.
I have had problems with Honda Bearings, ALM engines, as there are TWO sizes. (1.88" AND 1.89")
JUST a bit of FIY for ordering tech.

You are going about this the wrong way really. And adding in a small journal? Good luck. Its actually 6.3905 but 6.390 is likely close enough.
A few companies make a bbc 6.385 rod in a 2.100 crank pin but its a .990 pin. Even then youd have to cut the block. Next up is a 1.88 big end 6.378 with a .889 small end. still wont work.
Youd need a complete custom rod.
