Not much of an update, Just a couple of photos of the car as she currently sits. Almost completely stripped out. Been busy stripping and cleaning parts. Will hopefully get a few updates going soon as reassembly finally begins.

Realized my higher compression chamber shape was interfering with my pistons which just would not do at all. Currently going through the process of milling down the top of each piston. photo showing before and after of pistons 2 and 3.

Decided to rebuild this wee fellow before I paint it. Did not realize that it would be full of needle rollers. Managed to retrieve them all from the floor and rebuild it without saying any bad words. 

Don't have any photos but the rest of the steering assembly and sub frame is coming along nicely with everything cleaned and undercoated, ready for paint.

Painted my door cards tonight, here is a comparison between the cards before and after. Sorry about the quality, also the lighting makes it look patchy, they look much nicer in real life. Still a vast improvement though.

Bit of a lull between posts, however....

 

It begins (the rebuild that is). Head currently back with Glen for the skim after finally timing it up to check valve to piston and compression. Taking 1.5 mm off it to raise compression. Backed out like a coward on 12.5:1 compression and am now aim for 11.5:1, at least for now  :) .

 

Computer and intake manifold to go as well as some paint and wires. 

 

Shifting house next week so body needs to move. So here is the beginnings of the sub-frame being refitted to get her rolling. Will be coming back apart once safely in the workshop.

All the bits for the new speeduino computer showed up this morning. No more distributor for this engine. Going to use this to run crank fire ignition. Time to dust off the soldering iron and see if I have retained any electrical skills.
