Hello, my friend has bought a 73 charger with a 400 motor. Car has sat for a long time but runs great does not smoke but has oil leaking from just about every seal.We would like to fix all the oil leaks by replacing the seals/ gaskets but we are not sure what kit is best. Thanks for the help.

Felpro regular  FS7891PT11 kit is quite enough even with mild performance engines but get metallic headgaskets instead the composite ones coming with kit ( if thinking on refresh that too ).

Valley pan ( intake manifold ) gasket can be reused if in good conditions. I have reused it  many times.

if engine is a Magnum, it should get windage tray, which it means will need to get an extra oil pan gasket aside the one from kit

you can get just the outer seals too separated if don't want to deal with the full set. But the only parts you won't deal to replace all the outer seals could be valve seals and headgaskets. Rest can be used from the kit, including timming chain cover and crankshaft rear seals, which is two pieces.

and remember, if magnum engine will need an extra oil pan gasket to install on both sides of windage tray. Kit just gets one.
