While reading through the mod man intake thread earlier this week I read a linked article referencing a 360 magnum block build:
Valley Performance and Machine Service’s 376 cid Mopar Engine

Personally, this was the first time I’d heard of an engine block(amongst other parts) being cryogenically treated. It was my previous understanding that this type of treatment left metals harder, but also more brittle. However, I kept digging and found that the process has changed over the years and that this is no longer the case(article linked below). I am considering having my own block treated as well as some 727 components. Has anybody here had a block or other parts treated? Any input, links, articles, or experience would be greatly appreciated. The treatment itself is fairly inexpensive especially considering the potential strength gains.

If you can afford to have parts done, it is worth it. Cams, cam gear and chains, rods, pushrods, you name it. Think of it like heat treating, as that’s basically what it is. Might be over kill for a street/strip motor, but racing, it’s worth is.
 
Give this guy a call he's been doing it for years tell ya' everything you want to know Hekimian racing.com
 
wonder how the rings seat in a cryo hardened block. Maybe some special no break in moly or plasma rings to use or a recommended RA for the cylinder walls?
 
Good for engines your gonna fire up and run flat out for 500 - 2000 miles. Nascar treatment.

You deep freeze the parts after the machine work and from my understanding they are once and done. But who knows ? Go for it if you can get it done cheap . I am curious?

Tungsten disulfide and Cerakote for heat and friction and longevity .
 
A good friend of ours has a cryo facility for race car parts. We had our ring & pinions treated & had significantly longer life in the Dakota. Rather than 3-4 seasons, we got 7-8 out of them.

Too many Cell walls burst, water expands 11 percent by volume when freezing. Its a great way to fleece the rich, Installing hope that they will be "unfrozen" in the future. This has been around for a while, havent heard of one person who came back after thawing. A major crock of **** !!

I remember that was a "Big Deal" some many years ago. Now this book I have " Beast Tech" explains ALL The Other Ways they have Hidden for the Evil to Survive. The Amount of Medical Tech they HAVE been Withholding, is Sick. BASTARDS...
 
I need rockers for a victor big block head. I have a choice of speedmaster, Hughes, or T&D. I'm probably gonna try the cryo ones from Hughes. About 2/3 the price of T&D.
 
We have a couple facilities in the Phoenix area that I grabbed quotes from. Average price for a block with main caps was $350. One facility quoted me $420 for block with caps, rockers/shafts and valve springs which is the route I’ll likely go. All of them recommended the parts be final machined before treatment otherwise you’re re-introducing stress that the treatment is meant to relieve. One facility which also incorporates a machine shop further stated that treatment before machine work would cause excessive wear on the shop equipment.

Also, piston manufacturer advised against cryo treatment on pistons or rings. My worry is that cryogenic block treatment is said to reduce sleeve expansion from heat. In that case could I be looking at piston to wall clearance issues under heavy load? Piston end gap?
