How are you going to adjust advance/retard under boost? Which mag you want; verticle that goes in dist hole or the one that mounts horzontal along side dist area driven by belt?

Just a point of veiw. Probably don't need advance as based on stock its all in by 2000rpm and there is only 12° of advance. Since it should be retarded some per lb of boost it probably can be set at 18° initial and will have enough retard at boost and not be too hard starting, I have several engines that start fine at 18°. Cam wise I don't see why more [or less] than stock is needed for a runner; if racing then go for it. I don't know for a fact if Fageol in the blown engines used anything other than a stock cam or what they did timing-wise, haven't found anyone  or any specs to say so. I will look see which mags I have. Will take a bit as the shed doors are snow -stuck. Seb.

Jim, I have a couple of Mags that came off of military engines, I will try and lay my hands on them on Monday.

After I asked about a mag, I started to heavily look into the subject.   I talked to Ed on here, he looked at the numbers on his mags.  So:

Wico X , FM XV5 , FM XVE , Lastly Scintilla.

I've seen in pictures a FM XV4 on a Crosley.

Instead of trying to find a Crosley specific unit, I started the search for something with a longer shaft- this is a incredibly hard thing to find. Most all mags are gear driven, right near the housing.

I ended up getting a FM XV4C (from a 4cly ford).  This does not have advance(may have a impulse though).   Either way I plan to cut & slot the top of the shaft, and attach the top guts from a Crosley distributor. This will make the advance work.  Will need to trim the lower shaft for the right drive gear.   Needles to say, "I have a metal lathe!".

Next I bought a Scintilla Mag (fits a vw 4cyl industrial motor from the 60's). Got it from ebay germany, so it was super cheap.  Of course the shaft is super sort, and has that more modern flat wedge slot coupling.  So the plan is to take the lower half of that Crosley distributor shaft, and housing, and make adapter to fit the Scintilla into it. 

Its gonna be taller than the engine!

If any of this works, I'll post pictures, and updates.
