    Keep us posted. I will be following your build.
    Do you have a base bike in mind?
    Thanks mate Yeah it will be more of a straight line cruiser, i may go with a three wheel trike don't know yet. Other people have made v8 motorcycles with these motors. I have a 76 Honda goldwing rolling frame, may have to stretch it a bit. Lots of R&D to do. https://www.youtube.com/watch?v=WEFJ9kkFGN0

    Cleaning still continues on the cylinder heads and cylinder,as i was cleaning this set of rocker arms one side pop off which should not happen as they are press on and i could see some grinding marks on one side of the rocker arm and this was the side of the block were one of the tappets was broken. Decided to chuck up the longer push rod and it is bent, the short one is OK. So replacement is required, will be a couple more push that will be bent i will find out as i couture with the cleaning of the parts.

    Malcolm Oastler built a bike with a Simca Vedette V8 in it some time ago which may interest you. He is an internationally recognised race car designer who has worked in both F1 and American open wheelers so he builds stuff properly.

    Good luck with the rebuild.

    It's a matter of opinion. I think the Tatra cars looks great, and of course I have very good taste.

    The V8 engines have been made since well before WW2. Very advanced stuff in its time.

    I suppose it is a matter of finding the correct filament material. I know the old time cap was likely to be bakelite, but surely there is some space age wonder material that could be used.

    If there was enough left of the pieces could they be glued together to form the model to measure from?

    Or is it a rush of excrement to the brain perhaps?

    3D printer blokes, is it possible?

    Or maybe go straight to electronic ignition.

    Not having any experience at all with 3D printing, of course I may well be totally wrong, but I would think that it would be quite feasible to make a distributor cap that way. Years ago I had an old magneto refreshed by a chap here in Tasmania who collects and restores old machinery. He had an amazing collection of tractors, all restored and looking in near new condition, as well as I would think, hundreds of chainsaws in similar condition arranged on shelves in a shed that held nothing else, all very impressive.
    When he had to make distributor caps or magneto distributors for restorations, he would glue the broken one back together if possible, and bog up any missing bits, and then make a mould before laying the part up in fibreglass. He did an amazing job of it, and from the outside they looked indistinguishable from a brand new cap, colour and even brand on the one I saw, - really smick! It was only when you turned it over and looked at the inside of the cap that you could see the glass matt finish. I don't recall how he did the terminals, but the caps were all fully functional.
    I imagine that if you were a dab hand at programs like Fusion 360, printing a cap would be a lot less work than making a mould and then laying it up in glass and fitting all the terminals in just the right spots and in correct alignment.
    It's all a moot point here though as the OP is doing away with the distributor altogether, another great project Turbine Builder.

    Thanks Ropetangler All good have purchase distributor and two distributor caps and two sets of brand new inlet valves for a reasonable price. Been in talks with Alec in the UK he is what he said about the rear crank oil seal and some pics of what he done they always leak oil with the rope seal so this will have to be done on my engine block.
    OK, lets get rid of that rope seal.
    Had to generate out the original diameter. there isn't enough meat there for a standard seal because there is a labyrinth behind it so you have to make do with that & reduce the thickness of the circlips & also reduce the thickness of the oil seal.
    Then you have to machine the finger off the crank & shring a new sleeve on & cylindrical grind it. No pictures of that sorry.

    Use nitrile cord in the 2 vertical seals instead of asbestos rope.
