New 355 gears. Pattern check

[A Body 440 WHY NOT]

So , I am working on changing out a set of 488 gears to a 355 set. Here is the pattern in the "paint". What do we think ?

That looks good if your ring to pinion backlash is within spec with that pattern.

Yes. I did put some pressure on the ring gear and spun the pinion.
I could put more pressure / resistance on the ring and run it again if you think it would help see the marks

I just did a set of Motive Gear 3:55 ring and pinion in my 8 3/4 that pattern came out very close to yours. I have only drove them 30 miles and I am happy so far. A little whine when you back off the go pedal at 70 mph
