Default 1/4 scale V8, first project.

Hi all,
I recently started designing a small petrol V8 engine, as I've allways fancied building one. I discovered this site and read what people were doing, especially Stevehuckss, and decided my plans were rubbish. So I've designed a much more intricate engine, compared to my first attempt, and have been machining for about 6 weeks.

Whilst I have taken pics at every step I won't put all the pictures up, as Steve is doing an superb job of chronicling a V8 build. I will be happy to answer any questions in the future however. This is being built with manual machines only. I think CNC machines are great, but I haven't got one.

Going to try and upload some pics now, of progress to date.

Outstanding work!!! Your crank is a work of art. I see you have it drilled for pressure oiling. Are you using any particular engine as a basis for yours?

Bore is 19mm, just realised I can't actually remember the stroke. Not at work today and everything is on CAD there. It's about 18mm.
George, it's loosly based on Chevy small block, but since starting I've decided I want 4 overhead cams. I'm struggling a bit at the moment though to design the cam/rocker arrangement, so it could well end up with a central cam.
By the way, your gearbox is another step on from my crank. Crank was fairly straightforward, if time consuming, but I think I'd struggle to make those g'box casings. They're incredible!
Cheers.
