Ok pm my email

I have a set of NOS Arias flat top 440 pistons, I think std.bore,if interested Ill get more info on them.

Lookin for rods not pistons anymore.l found some old trw L2185 ones l just recently got.

pm received. i'll get some pics late this afternoon & send.

Oh ok sounds good

Received the pistons

Congrats on landing some pistons for your build. Thanks for the photo as well. Is the 809 on the one piston the weight in grams?

Not sure what 809 means,could be

Anyone know the cast iron thickness of a 426 wedge block? Like the outside thickness of block?

They vary depending on which year and type, M.W. or street 426
I've never sonic tested the outside but I do know of some old time SO CA class racers that had the outsides machine thinner to be able to put more weight in the trunk and in the gas tanks
I'm pretty sure that they are not real thick, maybe between .160 to .220 depending again on where on the block your measuring and the how many times that sand casting mold had been used before that block was cast

It's a 64 block crack is around freeze plug area.

You have two choices on fixing that, take it to a cast iron welding shop or have it "drilled and stitched pinned "
I had a 1965 street wedge block that had two freeze cracks and a casting flaw in the crankshaft area at the bottom of cylinder #4 that leaked coolant that I had fixed at a cast iron welding shop in SO CA. The owner wanted that block fixed instead of using a 440 block he had due to it was the proper casting number and casting date for a 1965 Plymouth Satellite he had
I've heard that there are some new cast iron welding rod that any good welder can use now to fix cast iron cracks like your deal, but be careful on who you have try that
I've had several freeze cracked 906 heads fix the other way also, all things are fixable, not cheaply though
Good luck on your deal

Well im goin to try and get the cast iron welding rod to fix it through muggy weld and stick weld it with rod.or get that lock n stitch kit.they need know to the thickness of block cast iron on block.so they can send me the right kit.would you know the thickness anyone?

Try using a one inch mic through the core plug opening.

I have a Dakota 1000 sonic tester that I use to test cast iron and aluminum as well as other metals.
I've seen a cylinder wall vary .050 about in a area about 1.0 inch circle on the same side of that cylinder
My message is each block will be different in different areas, they are not precise castings
