Hey. I have a 1989 Camaro RS and it was my first car. I love it to death and plan on working on it. What I don't love is the 2.8L engine that it has. So if money were not an issue, I was wondering what I needed to do swap the 2.8 for 4.3 and how hard it would be to switch it from auto to standard. Any advice or links on where to get more information is greatly appreciated thank you.  

Doign a 4.3 swap is tough because they're very different motors. The 2.8L is a 60 degree V-6, the 4.3L is a 90 degree V-8. Parts won't swap over very easy.

Your best bet is to get the 3.4L V-6 crate motor from GM Performance Parts, part no. 12363230. It's meant as a direct replacement for the 2.8L V-6, so all your parts will swap over. It's rated at 160 HP.

Your other option is to swap in a 3.1L V-6 from a later model 3rd Gen F-body.  

Thank you. That information really helped. At least now I have a better idea on what to do than to just be dreaming. Thanks again!
