Default Head pounding please help

Ive been doing research to the max on this damn 370 build! I thought I had found a piston to work for stock crank and rods but looks like it has been changed to a 6.125 rod only!

Can anyone help me out with a mahle piston to work out with a 6.098 rod?

Id greatly appreciate it !

the previous part number i have is LS1314030F04 but it shows that its for a 6.125 rod

I think i have figured it out! LS1340030F04 is for stock rod LS134030F04 is for 6.125 rod

Notice the extra 0 in the stock rod part number!

but when i do a search nothing comes up!

this is what I found

The particular part number is LS1340030F04. It is for stock rod, stock stroke applications. The compression height is 1.340 they are for stock .945 pins, have -4cc valve reliefs, and weigh 404g ea.

Mahle's part numbers are easy to translate:
first 3 characters are the engine family LS1, L92, LS7 etc...
second 3 are the compression height 340=1.340", 105=1.105", etc...
the third 3 are the bore dia 030=4.030", 898=3.898", etc...
the last 3 designate design and cc's F=flat top, I=inverted dome, D=dome, 04 would be -4cc in this case.
