what year block?
By 406Custom300 - 12/30/2000 2:16:53 PM; IP 63.178.193.211
I have a block, think it's a 68 or so, at least that's what casting # were on the heads(C8AE-H). I have looked in ALL the normal spots on the block for a casting number, and can't find one anywhere. Both sides, front, rear, by the pan rail, by the starter, at the front by the water pump bosses, etc. The only things I see are 352(like most FEs) on front left, and at the rear inside the flywheel are, 66-427, along with the pressure relief boss, undrilled of course. I know it is a 390 block, the bores measured at 4.080, (has + .030 pistons in it), but I was wanting to know what year casting it was before I have it sonic checked) I read that later castings were of thinner walls, and not to waste time on overboring them. I would like to bore it to 4.13, as I have come across a set of 406 pistons, and would like to commence assembly of it. If this is a later block, I can save the 100 bones or so for the sonic testing, and look for an earlier block. That is, unless someone wants to donate a 105 block, hehe. Help me out guys.

 Beats me. I'm told they're somewhat spotty, casting-wise. [n/m] -- Mr F, 12/31/2000
