If the dizzy I have comes back not usable I'll either pick up a DSM dizzy or a pertronix module. I'm planning on running a CDI box with the electric dizzy, I was thinking of just biting the bullet and getting a MSD Ultra 6AL plus so I'll have a boost controller avalible for use when I need it.

yeah cool, people that make fast crossflows ditch the XE type for the EFI/EA onwards type, more stable at higher revs and used with an MSD box or similar. i didn't expect there'd be a direct fit, but that's a fair effort that gets it done still (the pertronix kit is simple, fairly cheap, and could go back to points very easily if needed)

Form the fordsix forum "You need a sacrificial dizzy XY-XB. Keep the '68 unit whole as a startup/spare one. I always say to start a new motor with a points unit, as it's 100% guaranteed to fire.The shaft from the sacrificial dizzy is TIG'ed to the advance plate of the XE unit, which is rebushed or reamed to fit the upsize. Main reason for doing this way is it's rebushing at the same time, so wear's eliminated. The hold-down collar is turned to match the '68 unit - thinner and smaller. Use an appropriate driven gear against the cam.That and bypassing the resistive wire, are pretty much the main details to your install. It's often a mongrel to get the hold-down clamp bolt threaded in while simultaneously dropping the unit home, but once you have a feel for it - no problem. Having a helper to rock the balancer pulley slightly, can assist.If you pull the dizzy right down, you need to make a tool for reinstalling the clip inside the rotor shaft bore. It's a hollow mandrel - nothing fancy.If the electronic dizzy is in reasonable condition (not needing a rebush), you might be able to just make a thick sleeve for the shaft end - depends on your skill and facilities at work.Actual recurving gets to be fun. It's beyond the scope of what I feel comfortable with. You need to run enough advance to max your possible torque peak (200 RPM below your shift point, typically) but not come in fully, too soon before. Add to that the need for negligible mech advance off-idle and you have two end-points... The bit in the middle is territory for either a dyno or skilled hand.I'll try to get pictures of the spare 221-converted dizzy I've got here. Waiting to build an engine around it." this seems to outline what needs to be done to make a later dizzy fit a pre xflow. not sure if it'd be worth the effort lol.
