9+ years ago when I disassembled my engine I bagged and tagged all the parts...after 9+ years, the bags disintegrated and became hard to read. The bolts that mount the bellhousing to a 216 engine...the 4 internal and the 2 exposed. What is the size, grade, length, thread on these?
Also, same information on the bolts for the rear motor mounts to mount to the frame, along with any associated hardware.
I have searched the forum and the manual but can't seem to find the specs for the bolts. I determined the motor mount bolts are 3/8", but want to know what is the right size/grade, and what extra washers are necessary. | | | | | Joined: Feb 2004 Posts: 29,777 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,777 | The bellhousing bolts are 7/16-14, AKA 7/16 Standard thread or 7/16 UNC. Grade 5 bolts should be sufficient, with split lock washers and no flat washers needed. As long as you get 1/2" or slightly more thread engagement after the thread enters the block you'll be good to go. 50-60 ft/lbs. of torque is normal for that size of bolt.

First of many "stupid" questions. just want to do this right. Tomorrow night I guess I'll mount the flywheel/clutch/pressure plate up. Preparing to drop the engine in the frame.

Joe What size/year engine? I do not recall reading that instruction in a Shop Manual for a 216/235/261? http://chevy.oldcarmanualproject.com/shop/1948_51truck/51ctsm0634.htmWe'll hear from a pro (hopefully). | | | | | Joined: Feb 2004 Posts: 29,777 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,777 | The flywheel bolt holes in the crankshaft hub go all the way through to the crankcase, but unless you insist on using water-thin synthetic motor oil, it's not likely a properly-torqued bolt would allow any leakage. I would suggest using full-circle star-type lock washers on the flywheel bolts instead of split-style locks, however. A little dab of brush-on Permatex Super 300 wouldn't hurt- - - -it's a good thread lube as well as a sealer.
