did this a couple years ago. put it into a 65 coronet.
3. Will need to go with electric fan (junkyard here I come).
mercedes fan is what I did. new controler out now. but the nissan maxima fans worked okay too.
4. I want to keep the Serpentine setup so it should drop right in, just need to have custome A/C and P/S hoses made, should not be a problem.
did this too. took both hoses taped together to get length to a hose shop in town. think it was like 50 bucks.
5. My current setup has radiator inlet on drivers top, and outlet on passenger bottom. Thats the same for the magnum correct?
yes. and I have a 26 inch rad. there is a gmc truck hose that works best for the upper hose. if you have a smaller rad, then not sure. but I went to the store and just bought a crap load of hoses to find the right one. the lower for me was on the other side. used the metal rad hose to a rubber hose to run it across, so not a big deal if it is wrong.
6. I have manifolds on my LA 360, will those bolt up to the magnum heads or will I need to go with some headers?
the mag ports are slightly different. technically they bolt up, but have heard of blowouts/exhaust leaks because there is very little holding at the bottom of the ports. take the manifolds with the motor. they worked perfectly for my car.
7. Motor Mounts should be same right?
yep. exactly the same.
8. Will need to go electric fuel pump. Exactly how do you set this up. Return line needed? How is that plumbed in?
well since you are going carbed, there are plenty of electrics that only put out 6 or 8 psi. you don't need a return line, but if you want, you can put one in. just need to run another line to the gas tank from where ever you put your regulator. but I would keep it simple and find the regular pressure one from holley or carter.
9. My LA 360 is bolted to a 904 trans using the aftermarket flexplate for proper balancing. Will this same flexplate work with the Magnum 360/904 Combo? If not what will I need to do?
This actually depends on which mag engine you get. the cut off is like 97 I think. 98 and up will use a neutral balanced torque converter and you can get a weighted flex plate for the 727 and bolt it up to the 904 by slotting a bolt hole from what I have read. I belive there are torque converter weight kits for the other. but I did it for a 727, so this is just what I read. someone else will have to tell you for sure here.
10. Will the car oilpan that is on my LA 360 bolt up to my Magnum 360. If not, what specific oilpan do I need to get?
standard la 360 pan works. don't forget the pickup. and use the la pan gasket, not the mag one. or it will leak front and back.
11. The ignition system that is on the LA 360 (pertronix II, Flamethrower II coil) will all swap over to the magnum
yes this should work fine.
12. finally I would like to upgrade the cam with a nice cam kit to give it a little more oomph. Something that will still give it a nice strong vacuum source for power brakes, etc...but still let it idle pretty smoothly as I drive the car a lot, a whole lot. I would like a nice middle ground between performance and still be very street friendly. What cam/spring/retainer kits do you recommend?
sorry, no idea here. kept mine stock.
