1)  Engine Log Book Pro Coming  We've been working on a major upgrade to our Engine Build Log Book, a Pro version.  It has many new features, inputs, and calculated outputs.  We haven't finalized everything yet, but expect to release it in the next month or so.  Some of the Pro's features include:

• Many new inputs and calculated outputs.     for a list.
• Larger screen to accommodate the many more inputs and outputs.
• Several new inputs involve calculating bearing and other clearances.
• Now you can specify if the cylinder or lifter bores have sleeves and you can enter block ID and sleeve OD for interference (negative clearance) to be calculated.
• More reports of related inputs, like cam specs.
• Surface finish is a major new input where you can enter measurements from several locations in the bore.
• You can click on an input name and get several options, including highlighting the related inputs, making reports of the related inputs, and more.
