They look it from the pics. Brian - 1971 Dodge Challenger "The Dodge, which was practically stock, just left the Mustang like you wouldn't believe."

Was there a stamp or number on the block. I know the v in the Vin is for six pack engine. Also what does a B stamped on the pad mean. Thanks Bob Mom & Dad let me buy a brand new 70 Challenger R/T 440 Six-Pack Super Trac Pack when I was 17 (Robert what is a 440 Six-Pack)

Anonymous Unregistered A	Do you dudes remember the old MuscleCar Review Magazine? There was an excellent article by roger gibson on correctly detailing the 440sixpack/6bbl engine I think it was the fall 97 issue. It states all 440-4 barrel was h.p. only all sixpacks were H.P.2 only however this has been debuked countless times since then!!

IIRC the 440 6 bbl had a different piston than the 440 magnum, pretty hard to tell if a block was a 6bbl if you couldn't see the pistons, or have the partial vin on the r/s of block and you knew for sure the vin was for a 6 bbl car......just my opinion,you don't have to agree or disagree......
