What were you missing? We were looking for some of the dimensions and data from the FR9 engine. Among machining projects like valve covers etc, we machine billet aluminum blocks for Ford ,chevy, r07, dodge, and a number of misc one of engine blocks. We had a number of requests for the fr9 block and thought we should start looking at that project. If you surf the net, you will find a dirt late model team running Fr9 heads on a aftermarket aluminum block.
