Ok, Michael, certainly more than one way to make it work.

 

The “Plugs” up requires no modification to the engine – other than you will need to extend your oil pickup for the sump which I placed below the block and of course make a sump.  So making the plate to cover the pan opening is probably the only thing that takes some care – the only really crucial area is to make certain the plate (I used 3/16” 6061T-6) seals against the oil intake boss of the block.  Any air leaks will severely compromise the ability of the oil pump to suck oil {:>).

 

I lined up the plate and the two bolt holes for the pickup mounting by cutting the heads off of two bolts, filing the head end to a point and then inserting the two bolts with sharpened points into the bolt holes – point outward naturally.  I then carefully line up the plate to block and clamped it there so it wouldn’t move – I then gentle tapped with a brass hammer over the two bolt holes and the pointed ends indented the aluminum plate exactly where the holes should be drilled.  There are other ways but that worked best for me.  I also marked several of the pan bolt holes for alignment then took it off,

aligned the pan bolt hold marks with corresponding holes in the actual oil pan and then clamped the two together to mark all the rest of the pan holes with a match hole punch.

 

If interested, I can send you a photo of my oil pan.

 

I did move the starter hole in the RWS redrive to match what I already had when using the Ross Drive, so you need to check and see if you need to – I would presume not - if starting from scratch.

Ed:

 

Yes, I agree with that assessment. The reason I am making that choice is that at my current level of knowledge I am better prepared to deal with the problems of tuning and operating a carburetor than those of developing a functioning FI system and am reasonably certain I can make it work and am also willing to live with the limitations of a carburetor. As I progress this may change and I may be better equipped to handle the complexity of the FI induction. Right now I am aiming for a purely gravity fed carb not dependent on electrics at all.

 

In fact I was considering switching to a plugs up set up to make a gravity fed carb even more convenient. Beyond the new "side saddle" oil sump set up what other changes were necessary for you to get the engine to operate correctly on its side? did you need to modify any of the internal plumbing/oil galleries on the engine to cope with the 90 deg turn?

 

I will touch base with Oly for his input on the carb matter.

Also, do not think that choosing the carburetor is going to eliminate potential problems, you’re simply swapping one set for another.  While carburetor (like the EC2) will certainly work, I encourage you to check with my friend Oly Olson who can reveal some of those associated challenges.
