The weight numbers I'm giving (some are more accurate than others, comments welcome!!) are as best I can estimate them, just stuff that belongs to the ENGINE but everything it needs to run:
* Complete engine, all cast iron (eg alum intake would be less)
* Carb=yes
* Waterpump=yes
* Starter=yes
* Flywheel/Flexplate/Bellhousing=NO (I give those to the trans)
* Fan=No
* Aircleaner=No
* Water=No
* Oil=No
A lot of those are "reported" weights, as you know there is some scatter in that so these are my best estimates for the above conditions.
