I have the oppurtunity (sp?) to get a 2000 LS1 w/T56 and fuel tank for around $4500, I have an LT1 w/4L60E in the car at the moment, I want to swap to a manual too, so theres $1500 right there at least, and just to do a cam swap and some fix'es here and there on the LT1 is another $2100, so for about $1000 more I could have an LS1 up there... besides the "sealed" fuel system, gauge hookups, and crossmember, what other expenses should I run into?

Thanks
