i have an 84 TA with a carbureted 350 and a complete tpi system from an 86 TA. Exactly how difficult is it to do this swap? And should everything bolt right up to my TA?

 

The hardest part is dropping the fuel tank and installing the high pressure fuel pump. Otherwise, if you know how to swap an intake manifold and modify a wire harness, its pretty straight forward. Definitely not for a beginner though. Get someone to help you and photograph everything.
