well, I'm done. The whole shebang...

If you're keeping it under 7000 then I would definitely say under 600 horse. If you're running under 7k rpm you COULD even step down one cam, gain more on the bottom end, losing anything over 7000. You'd just have to watch your dynamic compression. Make sure it doesn't jump up. OH and if you're worried about stock block, you can always get a girdle. They help block walk a lot.

My mind keeps telling me I'm high on the numbers. That a lot of other 414's out there don't make that. But damnit if I don't think those heads can make it. They sound awesome.

You'll have to let me know what you think of the hughest 1.6 rockers. I am really looking at them for whenever I go for new heads and such.
