I neglected to mention in my previous post, that the whiz-bang connecting rods do not use the standard Ford big end bearings which would normally be the required part. Instead, they need part no. CB-610P bearings, which are a type used on Buick vehicles (and many others). They are not expensive, but are not an item I have laying around the shed on the off chance that I may one day require a set.
I am yet to receive mine, so things are on hold.....again.
And so it continues.
