I have a small budget And a few necessary parts, engine tranny and high performance exhaust manifolds from a 70 440 road runner. I would like to know the procedure that needs to be done to the 1970 hp manifolds to make them work in a 69 dart gts body such as milling and where to mill at and how much to mill. the car has manual steering and manual brakes. it has a 727 tranny. And any information pertaining to put in a Rb in A body any information would be appreciated. I'm going to use schumacher Motor mounts.

did a 73 dart sport w/440 in the early 80's. This was a spool mount K-frame car. We used 69 383 road runner hp manifolds. I believe we milled both .060 they were tight but did fit.
 
You would save yourself a lot of grief if you just used the Schumacher tri y headers with the mounts.

Thank you for the information,do you remember if putting spark plugs in a difficult thing using cast iron manifolds
 
Yes they will be a PITA to change plugs. Have to jack up the car but the only ones i did like that were on a '70 440 6 pack 'Cuda
