Don't even think of doing that Every thing I've read on here about them has been bad about them Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

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

Not trying to stir the pot, but where today are Hemi blocks available that aren't $8k KB blocks or used up OE blocks for $6k+ in need of repair?? '65 Belvedere '68 GTX '57 Dodge pickup

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. DynoDave Walter P.

It was a very expensive build at the time and likely about the same cost as building with a regular hemi block. The heads flow alot of air and they look cool. If you had an industrial 413 block , 440 crank , you could use a standard 426 piston for a relatively cheap build. www.alsrapidtransit.com

A friend with a machine shop has done a few with cross bolted blocks & has a few cross bolted ones left. Stage 5 told me back then that the total cost for heads, valvetrain & intake was around $5700. I read an old Moparts post about one with a 400 block had pushrod/valvetrain problems but can't remember all the post said. I'd love to do one with a cross bolted 400 block.

All the pictures I've seen of stock Mopar wedge(B and RB) cross bolted blocks had the bolts going through the main webbing on the center three main caps, NOT good Mr.Cab Racing and winning with Mopars since 1964.

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.
