Hello all
... Though I will sonic test the bores I was wondering if this block had thicker cylinder walls than the normal 390 block. My thought is that these blocks were being cast for a 427 bore but did not have enough wall thickness to pass inspection. I am probably wrong but I would like to know what you experts have to say.
The additional webbing and the cross-bolt bosses were also seemingly commonly found in the '64 Mercury 410 blocks.
Scott.
