Bergy,, I have a question. I’ve always heard that 2 freeze plug, 2 bolt main 400 small blocks were better/stronger/heavier castings than the 3 freeze plug 2 and 4 bolt main versions. So I built my 406 with the two freeze plug casting. Can you shed any light on this? I’d appreciate hearing your feedback.
