Introductions & Greetings - New to ls1 tech whats up

Hey im new here got quite a few questions
U guys can hopefully lead me in the right direction

My car is 80 turbo ta pace car. Bought with big hole in block.
Go figure the 301 is crap.
I want to do an lm7 swap and turbo it with a t56 trans.

Spohn has a bunch of cool parts im jus wondering since there is no listing for an 1980 what headers and kmember front suspension etc and crossmember ill need. And also trans adaptor. I have a brand new viper t56 trans in a crate already thanks
