Cryogenic Treatment
Cryogenic Treatment I'm thinking of having my lt1 383 block Cryogenic treated... 2 major questions. How much more HP should it to be able to take before and after being treated? its a 2 bolt main 383 stroked with ARM main studs...
Also if it is already bored will Cryogenic treatments change the bores at all? Or cause any issues with my rotating assembly that is already fitted for the block?
Respectfully Champ.
If this needs to be move to the lt1/lt4 I understand but I figured its a bit more advanced of a question..

I'm confused, are you cryotreating the block only or the rotating assembly too?... I am not a proponent of cryo treating, but my perspective is that cryo treating may be beneficial for materials with incomplete phase transformations when cooled to ambient temperature. This is mainly applicable to steels which, depending on their carbon content, have some amount of retained austenite. The cryo treating process is thought to tranform the retained austenite into martensite which is harder and more brittle. I think the main benefit of this would be wear resistance and I would expect no legitimate increase in HP rating.

Listen to this^^, even if you don't understand the metallurgy part.
I also do not think cryo treating a block will significantly increase it's ability to handle rpm or power. If you think you need more strength, 4-bolt steel caps would be a much better and proven way to go.
Priority for engine money:
1) Heads, intake and valvetrain. That's what makes the power!
2) Short block. Enough to handle ^^^ plus a little.
Many folks reverse those ^^. They then have a low powered engine with an overkilled short block. Ain't fast, but boy is it strong!
