My 422 smallblock build

Well that’s kinda what led me to ask some opinions here. Jones recommended 246/250 @ .050” .562/.520 on a 110LSA. I thought the duration sounded about right but not nearly enough lift. I was thinking closer to 248/248 @ .050” with .620 ish on a 108. I was kinda surprised by the low lift numbers.


I'd call Mike back and ask him WTF? I don't like the split (no reason for it) and I certainly think the lift is horrible. And why the 110? You are just killing the middle to get a bit more over rev after peak HP.

If you can find that Hot Rod article on line it would be well worth your time to download it and read it.
