A couple of years ago I bought a 1980 olds and it had a 305 shagged in it and I was going to reinstall the org 4.3 back in it after a frame off restore so I bought a rebuilt 4.3 long block from a machine shop and a complete 4.3 with 80,000 miles on it now I think I am going to stick with the 305 so I have two engines for sale. I will take 650 for both if any one is intrested PM me with any questions they are located in portsmoth, Ohio
