**600hp sbm block limit? Or is it bs!!**
Thats weird, I must get lucky constantly. I have torn down my motors for various reasons and have yet to see this mysterious “main line moving” you speak of. I have seen it in other motors when they detonate. Smart people know how to tune their stuff. Ignorant people resort to name calling when their arguments don't work out. I guess reading isn't your strong point. Anyways have a nice day and I am proud of you for being able to afford a 5k block.
What names? Do what you want. Just don’t expect everyone to think what you do is all that and then some.
Blaming tuning for the main tunnel moving is at best weak.
Look at every aftermarket block ever. When you do look and see where all the extra materiel goes. They aren’t doing the weight just because. So let’s talk it through.
It goes into the bores. Why? Because they move. Production blocks are made for just that. Production stuff. If the bores are a bit thin it won’t matter when grandma is just driving to church on nice Sundays.
Or, the alternative is all the racers who want upgraded blocks want thicker bores because they don’t move as much. And ring seal is better because they have actually tested it. Of course, we could all say these guys are stupid and can’t tune and that’s why ring seal is compromised. I wouldn’t say that because I’m not that arrogant.
They add materiel to the main webs and pan rails. Is that just added weight, bragging rights or just because? No, it’s because the main tunnels move around like crazy. If you can reduce that, you can tighten your oil clearance, run thinner oil and make more power without killing bearings. It is added to the pan rails so when you add 4 bolt caps the block can handle the added load the pan rails see. On top of that, most aftermarket blocks come with at minimum ductile iron caps. Why? Because the caps walk and flex and move all over the place. Some use aluminum. The big spenders get billet steel caps with much more section area. The cap makes the block stronger.
But, according to you that’s because these guys (myself included) can’t tune so we beat the **** out of everything with detonation and such. We are that stupid I guess. Maybe I should pay you to tune my stuff so I can go back to production blocks.
Where else? They add materiel to the decks. Why? Because it’s ***** to keep gaskets sealed with thin decks. And you have much more room to set deck heights without compromising gasket sealing.
Of course, we all tune like crap and that’s why gaskets fail.
Thats just the facts. Like I said, ring seal, bearing life and gasket failures is why they make aftermarket blocks.
No names, just the plain truth.
What is comical is that you accuse me of not being able to tune and yet, I have given you the facts of aftermarket blocks.
Oh yeah, there is also the materiel used in them. But that doesn’t matter either because tuner can use any old block that comes long.
