Okay, hate to start another gen 3 thread but I kind of fell into a couple deals and do not know which way to go.

Deal # 1 Brand new 6.1 Short Block at a buddy's house that he wants to sell.

Deal # 2 Brand new 6.4 Short Block that was ordered and never picked up.

I can get a great deal on either one, but given these two short blocks, which one would you go with?

I want to build a N/A motor for a 68 b body. Carb'd, 11:1 compression, basically a hot street motor built the old way with a gen 3 foundation.

I understand they both have forged cranks, but the rods and pistons will probably be switched out for forged items.

Which one would you pick and why?

Which block is stronger? Please bear in mind that I will be getting a good price on either so I can use some of that money for better internals.

Thanks Moparts!!
