tti 2.5 x system on 72 demon 340 review

I just purchased my TTIs for a 73 duster with a non numbers 360. I have changed the k-frame and added J heads. Im runnin dynomax super turbos with the manifolds now. My question is how difficult is the install gonna be with a four speed and should I change the starter to a mini starter for future ease and accesability?
