Real LS7 454 Crate Motor Short Block

[92646]

This is a real LS7 crate motor short block that was bought new at GM in the early 90s. It could be one of the last ones made and it still has the 2-piece rear seal. The 4-bolt main block casting number is 10069286, date code is C190, the stamp on the pad up front is TO406XCH, the crank is forged steel and nitrated part number 3967418, it has the big 7/16 connecting rods with forged TRW 12.5 C/R pistons with a part number L23074 stamped on the tops. It has the factory windage tray and high pressure oil pump but they will need to be replaced. The motor was only used for a short period of time then put in storage in southern California. It will need to be rebuilt and the block has surface rust. I am hoping to clean and hone the block then reuse everything but I have not taken it to the shop yet. If you are interested I can have it torn down and inspected for a charge. I am asking $2500.00 but I open to any offer. If you can use this short block then e-mail me with an offer at [email protected].

I dropped the short block off at the machine shop today. They seemed pretty sure that it may still be standard and the forged pistons can be reused but I will know for sure in a couple of days what condition everything is in. I may be able to get the cast iron open chamber heads to go with this motor also, if anybody is interested.
