These crutches are handy for someone that has a long term leg, knee, ankle, foot disability and doesn't want conventional crutches. These are easier to use, less hassle. Your weight is more on your arms and takes weight off your legs. They are shorter than conventional crutches and thus easier to move in & out of your vehicle or home.

Very detailed and thorough book for general and performance engine building
This is a very thorough book on building engines, (in general), and also details building several specific engines such as the first generation hemi's, 354, & 392 and covers blown engines and normally aspirated engines. The book covers work on every specific engine part, and give details on how to make the parts better for more performance. A few parts could have been written a little better, but most all other sections of the book are great. I would highly recommend this book to anyone looking to rebuild these engines, and anyone looking to modify these engines for more horsepower and torque.
