Locate the car model-body in the left column, find the engine along the top. Where row and column intersect is the power to weight factor. Click on that number when it turns yellow and it will return the classes, weights, indexes that the car fits. A button at the bottom of the page will take you to the engine blueprint specs including all the legal pistons, rods, oil pans, cranks, blocks, etc. Some cylinder head listings may have some flow data available.
Merry Christmas!
