I am contemplating building a big block Chevrolet V8 for my next project. Kiekhaefer and Mercruiser used these Can Am style injected engines in offshore powerboats and that is what I plan to build. I want to include lots of detail and have decided on a scale of 3.5 to 1. Between 1/4 and 1/3rd scale.
First job is drawing everything up and 3d printing at this scale to see how everything looks. My progress so far.

I was privileged to ride in Dry Martini, a 1973 Cigarette deep v powered by two of these engines. It is owned by Mike Bontoft and is raced every year in the Cowes Torquay Cowes offshore race. I have a lot of pictures taken during the engine rebuild including the original gear cam drive that was swapped for a more modern drive. I'll attach some pictures. Let me know if you would like more.

A little more progress with the Kiekhaefer powerboat racing engine in Fusion. Waiting for new Filament from Prusa. Just had a very bad experience with damp PLA from another manufacturer.

I have taken to dehydrating my PLA reels after reading about problems with moisture in filaments. I modified a food dehydrator and then store the filament reels in vacuum bags. Not sure it is worth all the effort. I can see that there could be a problem during our humid summers but winters here are desert dry.

My poor old Crealty CR 20 died after hundreds of prints. Got a new Ender 3 V2 on the way from Amazon. Half way through a large RC model. Hope to start on an engine project next once I get the new printer settled down and running smooth.
