R6 440 block?

67 Power Wagon said
-didn't "Mopar" or Chrysler supply the race teams 426 Hemi blocks till '72? I BET that 440 is just a plane Jane and really, what would have the difference been in the so-called "race block"??? A more the normal cam, and a different crank? IF its a "bare block" its nothing more then a common RB 440..... You'll have to buy all the needed parts for it if its just a block, Cam, heads, intake, crank, all of it. BUT I'm merely guessing on that.....

Sorry, I think he's smokin crack to say its a '71 "race block R6 440"

I figured he was blowing smoke... It s a complete engine, carb to pan. Here is his ad
