Has anyone else received the new GM 19420382 LS3 430hp long block? I received mine today.
I pre ordered it at the end of November. I plan on dropping it into a 1955 BelAir 2dr hard top.
The production date is 11/19/20 and it looks like it was the 33rd one off of the line.
It has a 98-02 Camaro oil pan and all of the sensors. Ls3 heads and a harmonic balancer. No intake or exhaust manifolds, no coil packs, no flex plate, no water pump.
This seems like a great platform for a street rod engine. I plan on using FiTech Ultimate LS system on it using a factory Corvette intake manifold instead of the fabricated intake.
Hopefully the FiTech fuel rails and injectors will work on he Factory intake.
I was thinking of grabbing one of these if they have any left once profit sharing rolls around. I was hoping no body would stumble upon these. Please delete thread. LOL
$5k can get you fully built short blocks from ATK or Shafiroff or “insert engine builder name here”
then you have to purchase heads etc for a replacement motor its a hell of a deal. If your building a motor for a purpose, I agree with a built short block. If my motor went today in my c6 i would use this in a heartbeat <---- see what i did there lol
The Terminator X is bad ***. This makes me wish I waited before buying my VVT harness and ECM w/ a reflash . Only thing I wish for on the Terminator X is dual oxy sensors . The learning function is great. Just re-cam your ride, change cam spec section in the software and start her up
Market is about to be flooded with old school sbc stuff. This is a great deal for alot of projects!
I am selling my running 327 if anyone wants it.

I do believe these come with the light weight valves. The L92 style is a reference to the rectangle intake port design. The long block is listed as having 12629063 cylinder heads. Chevrolet's description of the heads is below.
