I was reading and thinking about engine longevity/durability and came to conclusion that i will send my dissambled engine components to be cryogenically treated and after that send out my block for hot honing. Cryogenic treatment removes built in stresses and hot honing makes cyl bores as as round and square as they suppose to be at operating temperature.

Right now im calculating how much shipping and labor will cost.“Cars are the only thing on earth that will beat you, break you, make you bleed, make you cry, spend all your money, spend all your time, not work and not care that you will love more, the more they abuse you.” -AnonymousComment

Are you looking for a stock-purposed block, but one that lasts a long time, or a race engine that sees much higher stresses?
What is a DART block?
To a realistic extent, these engines last 100k no problem, 200k probably, 300k sometimes.
Wouldn't it be cheaper just to rebuild every 200k or whenever something breaks? I'm with you, there's a romance to building something to last forever, and a cynicism tied to planned obsolescence. But sometimes, it just makes more sense, and is cheaper in the long term as well as the short term, to build something cheaper and rebuild it more often, than to make one thing to last forever. I remember watching one of these shows where they knock down buildings, and there was a stadium somewhere, and a hotel in las vegas, both of which had cement and rebar to specs that should have held them standing for 1000 years, far stronger than anything the ancient romans did... and yet, real estate prices, run down interiors, and fickle fashion (times had moved on from both the stadium, and that hotel), saw them knocked down after mere decades.
The special treatments still don't take care of gasket materials, which need to be replaced more often than hard components, require just as much labor to get to (a rear seal, or a headgasket, say), and fancy metallurgy won't fix that.
Finally, I'm not sure about cryo treating relieving stresses... I thought it was supposed to harden steel (perhaps, making more stresses to achieve this): usually it's annealing that removes stresses.
Dunno about hot honing. Sounds like not a bad idea, although, presumably when ford engineered their tolerances it was so those numbers cold, became even tighter fits hot: so if you machine it hot, the specs will be non-stock. It also might not be a significant difference.
I wonder if other advances like steel sleeve inserts might create more accurate bores than hot honing will ever get a stock iron cast block to?Comment

I want it to last as long as 4.6 can like 600k a that I had seen.“Cars are the only thing on earth that will beat you, break you, make you bleed, make you cry, spend all your money, spend all your time, not work and not care that you will love more, the more they abuse you.” -AnonymousComment

agree with the DART block or something similar that is designe to handle over 800 hp and then some89 townie, mild exhuast up grades, soon to have loud ass stereo....Comment

Bernie DART is a company that manufactures blocks, heads, intakes etc...the blocks are overbuilt like crazy and can take more abuse than you could possibly throw at it.

I guess its just a wishfull thinking. On the other hand today i bought a zero hours ford racing crate 302 for grand total of $100. The seller explained to me that it was his grandpa's that deceased.

hah, I'm jealous on that one! that's a steal.
And holy... that is one massive main. What does a DART built 302 run? (cost wise)Comment

I think just block costs 5 grand.“Cars are the only thing on earth that will beat you, break you, make you bleed, make you cry, spend all your money, spend all your time, not work and not care that you will love more, the more they abuse you.” -AnonymousComment
