'68 318 to carbed Magnum 5.2: Check my checklist

If you want to use the magnum fan, you have to use the magnum front dress (water pump, timing cover, etc)...it's threaded on to the water pump stubshaft, so unless you modify the fan/clutch assembly to fit an LA style pump, it won't directly bolt on. A factory A body LA fan shroud fits since you'll be bolting on LA style accessories.

Point taken - though I forgot that the older fans are clutch style to begin with, and not flex fans. Either way, all I need to do is stick with whatever fan came from factory to the water pump that I ultimately use.

I also considered whether it would be ultimately cheaper to stick with the stock MPFI and Magnum serpentine by adding in the cost of a Tanks Inc. EFI tank and pump. It was a serious consideration for a while - until the LA 360 showed up.

I don't have the ps pumps in front of me, but if you don't have a saginaw style pump, I'm pretty sure it won't be a bolt on affair--do you have a shop that can make you some lines? Or if you have a legit parts store near you, they have books that you could probably sift through and find one with the correct ends.

The car has an early Saginaw pump in it, not a Federal. I wouldn't be against using the late, spam-can shell Saginaw from the LA either (especially if I can kick the original pump on eBay for a few bucks). I also have a spare from a junkyard slant six 1976 Aspen; don't recall the type. At any rate, I hear the van-style brackets allow it to fit, so if I go with the LA 360 from the yard, I may not have to do much experimenting at all.

Lines won't be a problem. I'll have to get them done for the Sanden AC unit anyway.

If you get a 360LA that's a little different, but B&M makes a the counterweighted flexplate so you can use a neutral converter. If you have a 360 available to you, and it's a good price, I'd almost say go that direction.

here's the flexplate for the 360LA/904 swap: http://www.summitracing.com/parts/bmm-10239/applications/make/dodge?prefilter=1

Of course, I could have counterweights added to the 904 converter instead of the flexplate (IIRC, the only option if running the Mag 5.9 due to the crank position sensor), but this is undoubtedly the most convenient solution.
