Ok so I sold my old iroc last fall and like always I got another one I picked this one up for 1000 bucks. Its been sitting for the last 5-6 years it runs but very rough. What should I replace right away I plan on changing ALL fluids, brakes,plugs,wires,cap n rotor. It needs an intake gasket any other stuff I should just replace? I wanna get the old 305 running decent ad then this winter swap in a 5.3/six speed but for now I just want her running right. Any suggestions? Thanks in advance the car in question:

 

I would ohm the injectors, and replace the fuel filter as well.

 

It looks like the swap may come sooner than expected I drove it about 3 miles from where it was being stored to my garage and the trans crapped out,fan siezed and it overheated. So unless I can find a dirt cheap trans to slap in its probably gonna sit a few months while I chase down parts for the swap. I also have a buddy doing a 5.3 turbo swap on his chevelle right now I may just take notes and go the same route. I figure there's no point in spending tons on a motor and trans I plan on dumping anyway.
