This is a very much needed thread in this community. Way to go OP.
An LSX swap is crazy expensive. If you have an LS1 laying around then yeah maybe. But at the end of the day you can just buy a built car that already has an LSX in it and save you money.
Just to put things in perspective since I backed out of the MHI group buy. I've bought 2 vehicles one for the wife and the other broke into the low 11's, then got it to break into the 10's. Now I'm going turbo with a progressive boost program hoping to get closer to the 9's. I won't break 9's until I swap my block out for a built 383.
All the while GTM sounds like they are in the same place they were last year with the group buy, customer support, products that have failed, so on and so forth.
