Cam choice for low compression motorhome 440

Really guys? a Whiplash or Thumper cam?

There was a reason that the factory used a small duration, wide lobe separation cam in the low compression engines. I wonder if it had anything to do with engine vacuum?

What does Hughes say about the Whiplash cam?

"Your vacuum should be in the 9"-11" range using this cam." Uh-huh, should be.

"Idle: Very, very noticable (sic)."

"Vacuum: Medium to low." (italics mine)

Do you suppose the Thumper is any different?

You really want to gamble with a retiree's money? Do you?

P.S. I've never seen a motorhome engine above 8:1 compression.
