Gauging Interest in "BIG" CID LT1 Block
Yesterday I called Dart to get their published flow numbers on a set of Dart heads I recently bought.
In the conversation with the Tech Support guy, he mentioned that Dart is "considering" casting one of their SHP blocks to become, essentially, a BIG CUBIC INCH LT1 block.
Dart would make the necessary modifications and cast the block to take the LT1 to the next level, but management was concerned about whether there would be enough of a market to defray the costs.
When I mentioned 4.125 bore as standard, his response was, "Oh, a 4.125" bore would be tiny compared to what Dart's considering".
So based on that, we're talking over 454 cubic inches with the new LT1 block which would accept all the LT1 accessories; including heads, intake manifolds, starter, alternator, water pump, Opti, power steering, etc., etc. He mentioned that it would probably be a two piece rear main seal arrangement.
Now, I didn't get many more details, like probable cost, etc., only that company management would have to gauge the demand before agreeing to move in that direction. Remember, this is only in the "consideration stage" right now.
I told the Tech guy that I'd post a thread like this one to see just how many guys would be interested in buying such a block. So if anyone's interested, post a response here and the Technican will review what's written and pass on the responses to management.
I intend to post this thread on several other Forums, too.
Just thought it might be of interest to some.
