Guest shadetree77 Posted November 24, 2011 Share Posted November 24, 2011 I have a chance to buy some parts that came from a 1953 Straight Eight 263. Will the parts be backwards compatible with my 1952 263? They certainly look the same, but looks can be deceiving. Does anybody know if they made any significant changes between the two years that I need to be aware of? The parts are varied but I'm for sure looking at buying the intake and exhaust manifolds and the rocker arm shaft assembly. Link to comment Share on other sites More sharing options...
Aaron65 Posted November 24, 2011 Share Posted November 24, 2011 The only differences (that I know of) is in the rocker shaft assemblies--you could get either solid or hydraulic...make sure to get the right one! Link to comment Share on other sites More sharing options...
The Old Guy Posted November 24, 2011 Share Posted November 24, 2011 The cranks have a different flange for the manual and dynaflow. Make sure you get the right one for your tranny. Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted November 24, 2011 Share Posted November 24, 2011 Robert, grab the manifold. Good ones are scarce and they will work on the older 248s as well. Ben Link to comment Share on other sites More sharing options...
