Hello! This is my first post after reading the site for 3 weeks. I was given my Fathers 1970 Duster 340 4 Speed when I was 17. I raced the car with high school budget 360 I had built for my 1970 Dart Swinger. (I sold the Dart and put the engine in the Duster in 92. Car sat from 97 till about 1 month ago. ( I started it up about 3 times a month.) Anyway I opted for 273 Adjustable rockers when I did the 360 build up ( got them out of a 273 in the junk yard) They are clean but the locks seem to back off and I noticed when trying to adjust them one of the push rods is a tad longer then the rest making that impossible to adjust that rocker. I bought a stock setup off craigslist and was dissapointed in them. Take a look at the pic. I still have the 340 together stored and used the rockers off it. Engine is in great condition for 100 miles. Left shaft is galled and I think it is a gonner??? can it be smoothed out? Right is off the 340 and smooth bearing like surface. Any one using used stock rockers on the mills they have? I hope this was not to long! I have lots more pics!

The 340 motor has been out of the car since 1990. The heads are stored. Block on top is a 340 I found in a 1971 Duster 340 in a junk yard.

273 Rockers on a 360 if you have not seen the set up.

You will need the cupped push rods if you fancy this setup.

The stock 340 rockers off the 340 that came with the car. 100 miles but great shape.

I have not raced the car since 96. Best time was 12.55 at 105 1/4 8.05 at 85 1/8. Going to find out this month.
 
another photo of the galled shaft and rocker. Oiling problem or shaft installed wrong? I will never know. Has anyone repaired a galled shaft and rocker?
