400 Non Stroker Build

With the raised height of the 440 slug sitting only.027 in the hole, as the guesstimate is above, with a 72 cc Edelbrock head, that inexpensively price unit, you could get better than 10-1, 10.5-1 *I think.* But this I don’t know for sure.

I have two 400 blocks I’d like to get to one day soon. Using one as a stock stroke would it bother me.

Then what to do for valve reliefs? IF the pistons are thick enough, it presents extra cost that could have gone towards custom pistons.
