LT 1 available from Chevy
Discussion
I just got a look at the 2015 Chevrolet hipo parts book and it lists the availability of an LT 1 crate motor with a dedicated ECU. Direct injection, Dry Sump, 11.5 to 1 compression 465 hp 465 ft lbs. With this engine being a bit smaller than the LS it could be a great choice for the Ultima. Lee
By a bit smaller I mean that I have read that the outside dimension of length I believe is about 3/4 on an inch shorter. I also believe that you are incorrect about the need to deal with eliminating sensors. The engine is offered by Chevy as part of their E rod program, which intends to deliver an engine to a hot rodder that can be plugged into the optionally supplied ECU and run as is. To this end Chevy supp;lies one of two different ECUs one for an auto trans and one for a manual. with the same bell housing as an LS and engine mount kits available the only questions that would remain is headers, will the drysump pan fit in the chassis and can you reverse the intake manifold.

No sorries necessary, I just think that for the guy that wants to build a great running car without the ego need to brag about how much horse power he's got, this motor might even be a better pick than the LS3. I have thought for a long time that the LS3 modified with a dry sump was the smart mans choice. but time marches on. By the way as a point of reference I have a 565 hp LS1 with 575 ft lbs soo when I take that shot about ego needs the gun is pointed at myself. Lee
Both the Jeg's and Chevy listing for the engine included the high pressure pump. It would be interesting to know if they use a "lift pump" or a high pressure pump between the tank and the engine. Another words is a high volume low pressure pump feeding the high pressure engine mounted pump sufficient? with a 2.19 intake valve and the aggressive cam timing that the stock cam has, with an 11.5 C/R without cats and a good set of headers I bet this thing would break 500hp at the flywheel.
