I am pulling the original 307 motor from my 1970 Chevelle and putting in a 350. I want to store the original 307 motor "permanently" on an engine stand. What size bolts do I need to bolt the motor to the stand? Also, is this a good way to store a motor for a long time? The car is a 50,000 original mile beauty and I want to keep the original motor.
Thanks.

If its a complete engine bag it up with some kind of desicant to keep out water, and let it be. It should keep for a quite a while like this. I have heard of people of course doing more extreme things. One guy just immersed his entire block in a barrel of used oil, not gonna rust that way!

The bolts are 3/8-16 (course thread),at least a grade 5, by what ever length you need.
You can keep an engine on a stand. Remove the sparkplugs,squirt some oil in the plug holes and rotate the crank a couple times a year and put the plugs back in finger tight.
An engine cradle is another choice. Near the floor and no chance of tipping over.

I'd consider building/buying one of those lower engine cradels (when I hear "engine stand" I am thinking something that has the engine sitting 3 feet in the air)... I have one I bought, and built two out of wood and casters... Strudy enought to support the engine, easy to roll around (when cleaningth garage, etc), yet less prone to tipping over (got any kids around?)...

Generally, you will need 3/8" course thread bolts. These will fit the motor mount holes and the bellhousing flange bolt holes...

I'd measure the "thickness" ofthe engine stand arms, and try to get 1/2" to 3/4" longer bolts and washers. Want to be sure you have plenty of thread engagement... Storage, Grade 5 hardware store bolts should be fine... I use Grade 8, just because its a little better. and whats a few cents extra?..

Thanks, I went ahead and got the grades 8's....I got 4 that were 4" and 4 that were 3 1/2". One of those sets should work.
