Did you fill the block? What casting number? Did you sonic test the block?
I have a database of 396 blocks and their characteristics.

So you guys calculated the exact amount to deck the block?

Answers to last 2 post.

Dwight the block was not filled but passed sonic testing. I don't have casting # om me but know it is a 1965-1966 block. Has ungrooved rear cam journal, we will groove the cam I have. Also have canister type oil filter, will get adapter for spin on.

Mark yes we did. Basically cam up with same deck height the original 396 had. I will be using the rotating assembly from that motor too.

Will - Probably a 961 block. I have found those to be mostly good. At least they don't have the core tilt I have found in a lot of the '67-'69 blocks. Good luck!

I've got 3 2 bolt main 396 blocks out in my store room. I'll look at and write down the numbers and we'll ID what they are. You got me curious.Isn't there a grooved rear cam bearing available to enable the use of the later cam in the early block? I know that a 409 has a grooved rear journal on the camshaft itself.That must be where they got that from on the early 396.

Two of the three blocks are # 3855961. Both have fully grooved rear cam bearings.The other block is #3969854. It has also a later screw on oil filter,the other two have canister type filters.

3855961 blocks are '65-'66 396. Interestingly, some '66 427's also had this casting
number.

3969854 is a '69 396 and was also used in the '70-'72 402's.
