I build in the neighborhood of 100 gas and diesel engines a year , and have done this for over 30 years.Some are over 2000 HP. The rear end of all engines I build in the most cases is the flywheel end. All though there is a few exceptions to the rule.
Thanks Manticore for clearing it up for the newbie.
Sparksy : It's just you!!!! You know where you can take the rear of your engine and stick it ??
