I don't have a dog in the hunt, as I have zero experience with the 470 so take this for what it's worth. Nuthin.
I've done a PILE of reading on big block strokers, since I was considering one at one time. It seems to me that two displacements stick out from all the rest. The 451 and the 470. The 451, obviously because it can use a lot of factory parts and off the shelf pistons, which can make it affordable. That was a big plus to me, as, unlike a lot of yall, I don't have money fallin outta my asshole.
The 470 though seems to be just as good or even better a combo. Since I knew I couldn't afford that one, I didn't do the reading I did on the 451, but if I remember, doesn't it use a Chevy size big end on the connecting rod? That makes for readily available rods = affordable. Buy beyond being affordable, the 470 just seems like there's something magical about it. Kinda like the 340. They make power almost effortlessly. With the 4.150 stroke and the 4.375 bore, you still have an "under square" engine.......which "most" agree is the better way to go. I'm no engineer, so WTF do I know other than what I've read?
