They both also use the same PVC and breather. But to call a /6 a highly refined racing machine and a 426 Hemi a boat anchor is kind of silly don't you think ?
Since there was a slant in 1960 in a race trim Hyper Pack, no, it's not silly. 7 Hyper Pack Valiants took the first seven spots in the then new compact car series at Daytona. NASCAR decided that since the Valiants had dominated so strongly, they would cancel the new compact car race because they thought it would be too boring for spectators. Since that was a full four years before the 426 hit the scene, I wouldn't call it silly at all. ...there are a few more Mopars that use plug tubes, though.
