With the bolt removed, how much of the crank snout is visible in the balancer's bore? IOW, how deep in the bore is the end of the crank snout?

I don't know why the pulley doesn't line up. It could be that the damper is made wrong or it could be that the damper isn't fitted properly for your engine. Aftermarket dampers often need to be honed to fit. Mopar dampers require a special press fit to work properly. You need to measure the OD of the crank and the ID of the damper and look up on the chart to see if you have the proper press fit. If it is too tight you have a shop hone it out. If it is too loose you return it or throw it away.
The upside down numbers are because someone stupid made that damper. Could be the mfg fault or it could be Summit's fault. Evidently someone in the loop didn't know the difference between a Chevy damper and a Mopar damper. There isn't much you can do about that other than complain to Summit.
If you look close at the picture on the Summit website you'll see that the numbers are upside down in their picture. So if you complain about the numbers they'll probably tell you to pound sand since you got what you ordered. Sorry about that, I've learned that one the hard way myself. I used to assume that everyone would sell me good parts but now after 40 years of working on stuff I've flipped my opinion. Now I assume everyone is too stupid to make good parts and that I have to double check everything before I buy it or install it.

Measure the distance from the shoulder on the crank snout where the balancer bottoms out to the end of the snout. Compare that to the depth of the bore in the balancer to be sure it's actually bottoming out on the shoulder.

Hope you have a GOOD puller b/c you'll likely break a cheap one trying to get it off. If you have to heat the balancer to get it on, then it's too tight and needs to be honed. If it's that tight, then it'll gall up bad when you take it off.

Yep almost all the aftermarket balancers I see need to be honed for proper fit, pulled off plenty that when they were installed rolled metal off, and they did not go on all the way.

I checked the water pump pulley belt grooves and they are out of align with the grooves on the crank pulley by the same 3'8" as mentioned previously so I believe the balancer is not on all the way. I will have to get a puller to take it back off to measure the snout and the bore. Assuming the problem is that the balancer is not on all the way and I can get it all the way on using a balancer installation tool, being the timing marks on the balancer are the wrong way could I use timing tape instead? The reason I ask is I bought this balancer about 5 years ago so I know I can't return it but I would like to use it so I'm not out the price I paid for it. When you take off the crank bolt you will see how far in the snout is and just some indecation if it is out too far.when you pull the balancer you will need to use a medium hammer to shock the balancer and it will likely come lose.You can use a timing tape but while you have it off you can get it marked for timing by someone.

JUST installed the same one on my 1975 400 stocker, looks like same distance on, had to draw the last 1/2 inch with impact wrench. I used just 1 pulley for mini alternator so no help there, my timing marks look the same set at 35* did not see a problem
all parts are sold as is, all parts are considered used no warranties or returns paypal/check/money order, shipping is from zip 02891, buyer pays paypal fees 24% IRS 1099A plus 3% of part price, check/money order preferred site is not monitored 24/7 there might be a delay in response

With the bolt removed, how much of the crank snout is visible in the balancer's bore? IOW, how deep in the bore is the end of the crank snout? 3/8" I would expect to see less. Measure the distance from the shoulder on the crank snout where the balancer bottoms out to the end of the snout. Compare that to the depth of the bore in the balancer to be sure it's actually bottoming out on the shoulder. I pulled the balancer back off today (came off fairly easily) and got the measurements you mentioned John. The depth of the crank to where it bottoms out is 1 5/8" and the depth of the bore in the balancer is 1 25/32".

I’d be a little surprised if there was no mention of honing the damper for fit, and the use of anti-seize lube in the instructions. But only a little. I used to assume that everyone would sell me good parts but now after 40 years of working on stuff I've flipped my opinion. Now I assume everyone is too stupid to make good parts and that I have to double check everything before I buy it or install it. I assume none of it fits.
