Also got a weight for a 20r (it was on wheels and the 22r's werent, so maybe I'll get a 22r weight another day)
290lbs with full flywheel/clutch assembly, distributor, and alternator. Some oil and coolant as well (basically pulled status)

I know it doesn't look it, but it is off the wheel dolly. I was lifting with a ratchet strap, and they dont do controlled release very well, so I wasn't about to raise the engine super high.
We race the 22r in a dirt oval truck, don't believe the internet that these things explode past 5500. We run 4500-6500rpm, with 4 years and counting on the first stock rebuilt engine. (Later style with single row timing chain)

I hope I am allowed to post this, it took a long time to find a list that I have at least some small amount of belief in it's content and weights. https://forums.24hoursoflemons.com/view ... p?id=12009

Unfortunately that list is decades old and the weights don't come close in a lot of places. I tried contacting the original author about 15-20 years ago to give him some accurate information and could never find a working email. Since then many many copies, some modified, have sprung up on the web. You can't trust it.

That Angelfire address has been dead for a long time; maybe ten years before the date on that list. The earliest versions predate the Web. Perhaps someone tried merging two or more versions.

I quit updating the list because, of all the things I've ever done on the internet, that list has caused me the most grief. I used to get bombed with *angry* rantings from people who didn't agree with it, and felt it was somehow my fault, instead of directing their spleen to any of the original sources I referenced.

Between that, and seeing edited versions "copyrighted" by other people, and the general hate the list seems to engender in a certain type of person, I quit uploading new versions.

In general, modern aluminum 4-cylinder engines are about 300 lbs, and the transmission/transaxles around 80-90 lbs, so figure about 400 lbs for the entire lump.
