Armed with digital verniers I’ve started measuring...

You can never have too many tools!! I had to alter my planned technique due to the complexity & depth of the injector holes...

I sometimes tell myself that when hiring staff.

Finally measured the injector centrelines, so I can get the fuel rails machined up! Ordered some additional parts for fabrication & waiting on the delivery... slowly, slowly!!

I’ll think I’ll test the EFI on the stock manifold before I try the custom one to confirm & quantify the benefits!

More inspiration in the form of cross rams!!! I’m putting a shopping list together with my EFI supplier...

I spoke with my fabricator yesterday & he mentioned these which I didn’t know about until then. It will all make sense later....

Strange that I found this in one of my cars.... At first glance I thought it was for the seatbelts but on closer inspection it looks like someone else had big ideas!

The visit to my EFI supplier was a success too!

Progress definitely slowed due to COVID but I have done a scale drawing! Always thinking of other ways to do it but my last design is still one I think will work the best. Simple is not always the best due to limited space & flow requirements. And although I’d be happy with a small bonnet bulge I doubt many others would agree.

Well this is a surprise! This appears to be an AMG engine with some interesting things in the background.... The SOHC M117 has an output of 460PS or 338kW!!!

This one is rather interesting but there’s no info about it on the web...

I gave up sourcing parts from Gates in the USA since freight was rediculous, even for very lightweight package!

I finally managed to find parts that will do the job from REPCO Hoppers Crossing who are not often renown for their cheap prices, but this time they did better than match the price from Autobarn!

Still scale drawing different sections & ready for the first mockup.

6.9 cylinder head intake is definitely interesting!

I don’t give up easily to the point where everyone thinks I’m crazy! But I figure nothing is achieved without pushing boundaries & being determined to continue in the face of challenges! If it was easy, everyone would be doing it!

Revised scale drawings & mockup underway. Engine stand purchased & transmission to be removed before the engine can be lifted into a more suitable working position. Revised parts list, standing by to pull the trigger....

I don’t know much about it, but I’m in love!! Probably not great as a street engine, but it looks great standing still!!!

Looks a little tame for a street engine think it's needs more airflow
