hi Dan i have a plan like that on an F —I contacted TTI their headers are listed for 62 up C body ( odd way to put it) but they say they have no experience with 60-61 “ don’t know “ “ never did it” To me , identical side space , 60-61 larger if anything lengthwise , changes there are quite involved and you have to think about it , as engine is in same place re body firewall , ( which is the same ) yet some ?4” less wheelbase so control arms have to be moved back on stub frame . That tightens up header clearance a lot at control arm . . And steering box . There also may be some kind of major change in steering box mount to frame , 60-61 mount to side of frame in lwb at least ,? swb? but somewhere around 62 or 63 up K frame is used too . Anyone know when this happened ? after market steering guys ( Borgeson) do not support 61 back , but seem to support 62 ? Talking to them went no where i would like to put TTI headers listed for 62 in a 60 , unless there is another path ? I do not think end of ram manifolds need any support . look at size of that casting many bolts to head . Have never seen one break . . It is thicker metal than 727 torque flite case ., Function of heat tubes is heat . Water cooled ones ( 405 ) did not have support ? not sure of that though . Can’t hurt but not needed imho . Did you use commercial headers ? stock ram log manifold is truly restrictive , why 405 J K and max wedge have what they have . … has to be 20-25 hp better Thanks, John On Jul 15, 2024, at 8:00 AM, dplotkin <dplotkin@xxxxxxxxxxxxxxxxxxx> wrote: -- For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang --- You received this message because you are subscribed to the Google Groups "Chrysler 300 Club International" group.
