Hey guys,

I was going to bolt up the 727 to a 1995 360 (I think its a magnum block) the other day and I was using 3/8" bolts and it seemed as if they did not want to thread. Am I usung the right size and thread pitch bolt? Anyone know the size off hand? These components were never together before its a new build so i dont have any "original" parts. Its not metric is it?

Thanks in advance,
Brian

I don't think those bolts would be metric on the Magnum blocks.

They're 3/8-16 NC, even the 4.7's and new Hemi's still use that size thread on the bellhousing bolts.

Thats what I was thinking, I may have to clean the threads up. What does the NC mean?
