Those folowing this thread, https://www.camaroz28.com/forums/sho...d.php?t=678840 ,I am putting this up to make sure it doesn't get missed in the middle of a thread.

If you want it, Dart needs to hear from you. On their forum, they now have a topic and poll. http://www.dartheads.com/dartboard/showthread.php?t=930 If you have a LTX and even if you don't plan building one now, this is huge news for us. My block I had is already dropped off to be shipped to Dart for measurements as well as the front cover. Please pass this information on to anyone that you know has an LT engine. The more response to this, the faster it will be made. We are really close to this and we can all thank my engine builder Jerry Clayton for getting this to this point. It is all up to you guys now. This is not a bench racing idea anymore, it is now a reality. Thanks.

If they make this, I will

Not saying its not great news, but I personally would not do it.

Going to vote now, they have an option for almost anyone, so I suggest everyone votes.

Although some may see it as a waste of time I personally am pretty f'in excited about this. Imagine a 440" LTX....

I'm all for it going there to post my vote right now!! And of course you always got the Debbie downers

Going to be interesting to see what the legal issues are. GM had to stop using the "reverse flow" cooling (ever wonder why the LT1 is the only engine to use it?) because the inventor of Evans coolant has the patent on reverse flow cooling, and won his battle with GM in court. Can someone now build and sell a "new" block that violates the court settlement with GM, or is this just considered a "replacement" block?

well technically if that were an issue wouldn't there be an issue with companies selling "reverse flow" cylinder heads?

That is a good question, I never realized it was patented. I always wondered why no one else ever did it. This should pan out to be interesting no matter what happens.

I'm not a lawyer, so I don't know the answer. I was just trying to raise a relevant question.

GM used reverse cooling on Pontiac V8's 55-59. They then went to the standard cooling like a sbc in 60-up. Of course when they did it on the sbc in 92 it became the LT1 we all love/hate.

The whole point of this block is to run a big bore, were not wanting them to build a factory replacement block. why would I want a factory short block with cast componets? I had an item patented back in 96' and my lawyer told me then that all a compeditor would have to do is change my design by 20% and be with the law, to put it in perspective 20% would equal a change in color..

cardo0 you keep talking about a waterpump pulley bypass. Sure some tow package b-bodies got a belt driven fan some of them Roadmasters, BUT they have the same waterpump as all the rest of the LT1s so you are repeately using bad information to try and press your point. That fan is on a seperate bracket, not the pump. Here is the mechanical fan setup, the large black pulley there is a duplicate of in the pic. http://s120.photobucket.com/albums/o...t=DCP_0500.jpg

You state the opti is great for firewall clearance(you are right), BUT this market if full of people who think they need to get rid of the opti to run 11s. I don't agree with them but that is what this market thinks.

It would be nice to see this made but I don't think it is anywhere near as "necessary" as folks want to believe it is. Bad combos are the norm around here and that holds the platform back way more than the block.

aluminum????

wouldnt that be some mud in the ls eye

I'm wondering something about the stroke. Looking at the SHP SBC block specs on Dart's website is says this:

Bore & stroke: 4.165” x 3.750” max recommended

Now does this mean that the largest you could go with this would be a 409ci, or maybe 422ci if clearancing for using a 3.875" stroke? Or would it be able to be safely clearanced for 4" or more stroke? I'm wondering if the cam position will limit the stroke to below 4"??? If this block is capable of a 4" stroke, and becomes a reality, then my 385ci build parts will go on sale to help fund building a 427 from this block instead.

4" should work
