LA 318 advice

Offset grinding with stock rods and undersize bearings? Any cautions when going with 2.1 or 2.0 Chevy rods with a factory crank?

No but you need to go to 2.00 inch throws to get any real increase in stroke length.

Then you need to find a 6.125 long SBC small journal rod.

Then you need to get the pin ends to .984 diameter.

It’s not a simple operation.
