ummm.. lets see..
Rods become your first weak point at 1200hp. Then crankshaft issues from main cap walk. So a girdle becomes a must.. Then your engine is pretty sold. I would think if your chasing 1200hp plus then you are running custom pistons designs so that would fix the next weak point...
The main thing to have to build a durable engine is alot of money.
I would love billet rods but can't justify the $2500 tag

I'll take a look at them. But iirc there ceramic coating is junk... I can't recall exactly but when I was looking for coatings I beleive there was some bad news about there ceramic coating not holding up. I was gonna use swaintech for coatings but i'll check them out.
Here is a great read for coatings... http://www.aera.org/ep/downloads/ep9/EPQ110_34-40.pdf

Thanks for the great read. Carl at polydyn is a cool guy,he has a built 7.3 daily driver. He's taking over the development of the alum 7.3 head. Wants to make it a two piece design. He coats anything and everything.

Been way to long! just kind of getting the itch again.. I got a wedding in august so that's been killing toy funds... but I did get a new bed.. It's on the truck but I can search down any good pics.. 08 bed.. like 60 miles on it.. got it for $500.. gonna have another one coming this year for my DD..
Got some various engine parts here and there.. I'm hoping to have the engine in for cryo sometime this year and then coatings.. maybe have an engine sitting on the stand by xmas.
