I just found this project and... I'm mildly stunned.What engine are you using? From the drawings it looks like an air-cooled four cylinder with a fan shroud similar to a real 4-cam.Any relation to the Polopolus engine?
Hi Gus , thanks for your comment , sorry for my late reply , we ( slide performance and vintech) design our own engine case , there is no relation with the Polopolus ( it's casting) and our engine , milled in big special aluminium bloc. it's a four cylinder , aircooled , the design of the fan shroud has to be very simylar to the 4cam , it's 3 liters engine .
