Anyone have a rebuilt lt1 for sale, or know of any website that sells reliable engines

 

I know that you can get remanufactured lt1 engines for the firebird and corvette from JEGS. It seems they sell them for ATK. They go for 2,300 dollars however I believe that is with the... core charge credit ? on the site it says the core charge is 400 dollars, shipping is another 180.

Here is a link for 93-94 firebird engine as an example. https://www.jegs.com/i/ATK-Engines/059/DCM3/10002/-1
