I'm swapping in a stock 96 360 Magnum into my 68 Valiant and want to make sure I have everything before I start, so can you all please double check my list?

-Schumacher /6-V8 mounts
-LA-style timing cover and water pump
-LA-style distributor w/MP ignition
-LA-style pulleys, brackets and fan
-V8 carb linkage


And a couple of questions:
-can I use the Magnum exhaust manifolds from a truck?
-when I go to the car oil pan, do I need to use a center sump pickup?
-since Im changing the timing cover, Im assuming I need to change the cam to an earlier LA-style (with fuel pump drive)
-I have a new M1 intake-is that too much with a 340-ish cam even if I use a small 650 carb? If so, what other intakes are out there for the Magnum heads?
-the /6 has a 904 trans and Im just going to use a V8 A904-Im assuming that other than the bellhousing, theyre the same?
-the Magnum engines are externally balanced(?); do I need a counterbalanced flywheel?
