Ok first of all, what the hell are you doing up at 4:31AM???
Second - ha, look at that, my old block! That was a good engine. It went low 12s on 7 cylinders.
I do have another standard-bore 340 block that is still in storage, I think it’s a ‘70. Plus an ‘89 360 roller block, two virgin 400 blocks and a 400-based stroker short block... Mo-Par central indeed.
