A list of those important figures on sizes and weights of popular engines to aid the aspiring engine swapper.

When planning an engine swap, it is essential to have specific information regarding the engine you plan to use in order to determine if it will physically fit. Consequently, we've compiled what amounts to the most comprehensive listing of engine dimensions and weights ever published in any one magazine. We've tried to include all of the popular American engines ( plus a few oddballs ) frequently selected for swapping in street, rodding and racing applications. If you haven't yet selected an engine for a particular swap, this chart might guide you to a comparatively inexpensive, less-popular engine that will fit equally well.

The dimensions given are for an average engine of the make and size listed; however, it must be remembered that intake and exhaust manifold variations on the same engine in different years or within different car lines may result in slight variations. Similarly, the dimensions given are overall measurements, including such things as air cleaners, oil filters, water pump fans, etc, but bellhousings have not been included in the length. Therefore, replacing such things as the air cleaner, substituting headers for the stock manifolds, using an electric fuel or water pump and remote locating of the oil filter will allow most of these engine to fit in even smaller spaces. Additionally, oil pan depth and sump location may vary. For example, small block Chevrolet V8 engines have been built for over 20 years, featuring low-rise and high-rise intake manifolds, a variety of air cleaner heights, different oil filter locations and different pan depths, and the pan sump was even located at the front of the engine on some Chevy II models. But generally speaking, this chart should help you stay in the ballpark.
