Starting a new thread since the old thread was nothing but speculation & rumors. This thread is the real deal! An actual casted LT1 big bore block and more!
This video was taken at PRI this weekend. Skip to 6:31 for the first video of the LT1 block, specs, & pics below! Enjoy!
Keep it positive please. A lot of people to thank for this!
The first post has duplicate links for the videos. This might be the intended link for the first video. As Rob mentioned, 6:31 for the LT1 block. Greg Banish is also in the video at 18:34 talking injectors and what appears to be an injector characterization machine.
It does exist, I have witnessed it first hand. I’ve finally jumped ship but there’s still hope for my fellow LS1tech LT1 idiots. You fucktards better do something with this, it’s been many years in the making now.
Looks like it makes it fairly easy to punch it out to 454 without issues according to the measurements they were talking about on the block the were pointing at. Raised cam, etc. Looks like a pretty nice piece.couldn't find anything on their website, m&m about it, but still, looks like a quality piece for sure.
Allows for a longer stroke. The official answer from the interwebs is:"The primary benefit of raising the cam location in the block is that it provides increased clearance between the rotating assembly and the camshaft. This allows you to use much more robust components which provide higher strength and stability."
