    Building a highly efficient engine (mpg)

    So I'm thinking about my next build. I'm thinking either a early Ford Ranchero or a Dodge Rampage. It'll be a small block v8 auto/OD. So the goal would be 25-30 mpg. I chose these two bodies for being smaller and lighter. I can make either one work. So the meat of the question is how to build...

    Schumaker motormounts be aware!

    Be aware of the terrible quality of these mounts. The hole for the .5 bolt is .700 and off center! I made a bushing to take up most of the slop. These should have been lasered & CNC bent. Looks like the holes were plasma cut free hand. I would not buy these again!
