OK, the 340,000MI 350cid in my 'Burb is getting really tired. I like to be diferent, and I see them for cheep in my neck of the woods alot, so I was thinking of a 4.3 for a replacment. I'm thinking that it would have a little more power than my curent V 7 (1 near dead cyl.) and might even get better milage. It would be a little lighter. And I have never seen one in a 'Burb before. Any one got any exp. with this, or advice for me? It's the one in my sig. SM465, NP208, 4.10's 35's striper model, only thing power is steering and brakes.
