While working as engineering manager (paper pusher), I needed something that was technically challenging. So at lunch, I began to eat at my desk and started designing my own v-8 engine. This is my own design of a SOHC engine. I have a lot of the parts made. But from the time I first got started to now, I've purchased a CNC milling machine. So the opportunities to make parts better is there. I've started re-designing some of the parts for CNC work. One is the intake. I decided to run 8 small carbs that I redesigned from plans I bought from Jerry Howell. It's really overkill, but I thought it would look better and be lot more challenging. Progress is slow, but I have made some...
Please feel free to take a look at what I have done so far by clicking HERE (http://www.ericchesak.com/Galleries/DIY/Mini-V8/)
The crank was done on my 1932 Southbend lathe that my Grandfather bought new. I have 2 lathes, but it's the only one that is set-up to turn between centers. The last 2 photos are more recent parts that I completed on the CNC. The last photo is one of the carbs that I did as a prototype on the 4th axis. This allowed me to machine 4 of the 6 sides in one set-up.
Comments, suggestions or complaints are always welcome.
Thanks for looking,
Eric

I'm not telling you that you shouldn't do it but carburetion on these small engines is hard enough to sort out even just using one. I would recommend starting with one to sort out all the bugs and then modify from there. Oh and I went to your link and looked at your construction photos. Nice work!

Beautiful work. Keep us posted as you build
I don't like work with anything smaller than a #4 screw. Don't know how you do it.

Excellent work, but having had significant problems getting a single to run I echo Georges comments (I am now adding to my problems by working on fuel injection ::) )

Very nice work, indeed.
