Flywheel bolts, correct size???
I'm about to bolt the flywheel to my new 383, and I realized I don't know what the correct size for the crank to flywheel bolts is. I seem to have misplaced my originals from my L-48 so I have nothing to reference. Anyone know the answer 
Also, when I buy the new bolts what should I use for a strength level? Grade 8? Hardended bolts? I'll also be sure to use thread locker when installing also. Any help would be great

These bolts would be grade 8.

Use the ARP or mid 80's Chevy flywheel bolts, you can get them cheaper from Pioneer at a local automotive machine shop (the Chevy bolts are quite good but, ARPs are the best.)
