I got the 69 Olds 350 today. Has less than 5,000 miles on it. The guy I got it from is looking for the paper work on the rebuild he said it has over 300 horsepower. Just got to get that dam 307 out my 442 now. Might just wait til winter to start that project. My 307 has 62,000 orig miles and has a tapping sound, going on 2 years now. Cant figure it out, so im going to replace the engine.
