Any opinions on Stage V conversion heads? What else do you need to make them run?

There was a time when Hemi blocks weren't available so there was a need, not so much anymore.
A friend built one of the conversions back in the early 90's (he still has it).
The RB Block isn't nearly as strong in the bottom end as a true Hemi block, no cross bolted mains on a standard RB Block.
Kayse can't keep up at all now. lol

But, if it's what you "have to" have, then I guess that's the going price. Which brings us back to the OP's question about this conversion.

So what if you used these on a 400 block? Stronger bottom end,larger bore and if you stroked probably a lighter piston. Any thoughts?

The way block availability is now, I think the conversion kit is a viable option. If I was in the market, I'd definitely be looking into it.
Anyone remember Steve Magnante's (from Hot Rod magazine, B-J Auction, etc.) red hemi dart? That was a Stage V conversion on a 440 block if I'm not mistaken.
Lets be honest here...most people building a hemi aren't looking to make block breaking power. Less than 600 hp is what most seem to be after and a stock block will last a long time doing that.

Why build a Hemi If your looking for 600 or less While I agree w/ your thinking (mine makes 4 digit HP), there are a lot of car show and cruiser guys that just want the look. Or have just always wanted a hemi. Back when they were available, I bet the "little" 465 hp crate hemis outsold the 600+ hp 528" crates 10 to one.
