Considering selling STI for C6 vette

My STI has been out of commission for a year and a half with rod knock. I’ve been wanting for the right time to get an IAG block and Cobb 20G, but more and more I’m considering selling it possibly after putting in an RA block and getting a C6. I have a lot into the STI (2 extra sets of wheels and tires, giro 2 piece rotors front and back, lots of Cusco braces, all the reliability mods, sway bars and endlinks, lots of different bushings, kart boy shifter kit , Cobb AP , grimmspeed intake, and more. but CA makes it hard to build for power. The reliability of the STI also scares me . It already bit me once. I’m worried I’ll dump 13 or 14K into to have 380 whp have another another failure.
