Oldsmobile sixes and eights manual

Anybody have a copy of Oldsmobile sixes and eights? I plan on taking apart 257 straight 8 and don't have any manuals. Does somebody know the weight of one of these engines?
THANK YOU

A rough guess based on estimated weight of very similar Pontiac Straight 8 would be between 700 and 900 lb. including manifolds, carb, starter etc. (not including transmission). I'd pick the middle of the range at 800 lb.

A few years ago I put a Chev straight 6, 235 on an modern engine stand and that was scary.The center of balance is way out there, the straight 8 will be even worse. Be careful if you are using a modern stand ment for a compact V8.

There's no way you can put a Straight 8 on an engine stand designed for a V-8. The straight 8 weighs close to 900 pounds and is far too long for the legs.It would be nose-heavy to start with, and there's no way you could hang on to it to flip it. I was looking to yank a Buick 248, and that thing was over 3 feet long and about 2 feet tall and weighed 900 lbs. I phoned the manufacturer of my engine stand and they told me if I attempted to put it on it'd snap like a twig as it was falling over on it's nose. I would not recommend even trying it, although I'm sure someone is going to pipe up and say they've done it and it's all fine.

Never heard of that one .
Your best bet would be a 1942 Oldsmobile Shop Manual . Along with a 1948 supplement .

I figured something like that might happen could i use the lift on the front on the engine to help support it?
