Speed Pro Piston Equivalent

I ordered the H825CP pistons from Summit in January and they have been on back order. I called them up and they said they are on a national back order until June. I just got off of the phone with Fast Engine Parts and they are out of stock as well.
Does anyone know of another place to buy these? Or is there a comparable piston, both in price and durability? I am building my stroker to run on e85 so I plan to have a CR ~10-1-.5:1.
Thanks,
Jason

The h802cp is identical in shape/dish to the 825cp but uses metric rings instead of standard rings.

but then you have to covert the whole engine to use only Metric fasteners don't you

Actually one of the worst aspects of working on mid 90's XJ's is the entire engine bay is a mix of Metric and SAE nothing like guessing as you strip the head off something... hhmm I thought that felt a little too loose... Oh well where are the vise grips.

I already have the std rings plus I believe all Speed Pro pistons are on back order.
Is anyone else having issues finding pistons?
What other vendors sell the Speed Pro?
If you are you another comparable piston, which one is it and where did you purchase it?
Thanks,
Jason

Have you considered the Silvolite 2229c - with, 1.581 pin ht, 11.5cc as it can be readily cc,d quite larger?

Where might I find these? I am open to anything comparable, but just haven't been able to locate a dealer.
I don't mind the 11.5cc as I am looking to run e85.

Did you try NAPA for the H825/H820 pistons, they switched to Federal Mogul last year as their source. Possibly there is some in their network?

I just got the 2229's at Summit - it looks like they are back ordered until end of March though.

Thanks for all of the suggestions.
I'm not sure what I am going to do. I have a hiking trip coming up in May that I have to train for and I was expecting to have all my parts in and my build complete before now (I started gathering parts in early January). But parts delay after parts delay has pushed me back so that I think I may have to wait until June when I get back from my trip, so I guess it doesn't really matter. If when June comes and my pistons still are not available, I now know what my options are for locating equivalent pistons.
Thanks,
Jason

I found 23 of those pistons on a shelf this morning at a local dealers. Contact me if you want their phone number. The Federal Mogul pistons.
