Rod orientation matters when there is a chamfer on the crank shaft. Have the larger beveled part of the rod face that counterweight chamfer of the crank shaft and the reverse for the other rod on each side. Otherwise the rod will bind. If there is no chamfer on the crank shaft and the rods are not offset it doesn’t matter. I still set mine up that way because it is good practice. Tang orientation doesn’t matter.
I had a similiar problem on cylinder 8 with a piston issue so I'm trying to locate one piston for the set. My question is 1) since gen one and gen 2 weight different can I still use only one gen 2 piston or should I just use a gen 2 set (if I can get it) and 2) will gen 2 pistons work in a gen one block as long as orientation is correct? Haven't been able to find out any info on forums...so thanks!
Yes bore is the same, this Gen 1 block with g2 pistons and rods on the g1 crank combo now has 1000+ miles on it in a blower car. Get a set of g2 pistons and rods they are stronger
Just replace them all with Gen 2 pistons so the other 7 don't continue being a failure point. Or at least just replace the rods themselves. Sell the old rods to recoup some of the money.

I always try to match the oem tang orientation
Thanks for Sharing this Information with us
My pleasure
The gen 1 rod does have a mark that faces the front.

@@Smasher-Devourer I thought gen 1 and 2 pistons were the same strength and only the rods were different?
