I think he could have made a better choice than that Thumper cam. Those always seem like a gimmick first
and performance second. A cam targeted towards maximizing that combo would have performed better than a cam
targeted at making a lumpy idle.
I had Oregon cam grinders spec a hyd. Roller for a motorhome 440 with 440 source heads. It was a low buck deal.
Their recommendation was a 230/239@050 .525/.540 on 112lsa install at 108.
I used this cam later in a 9.5 to 1 motor with sidewinder heads. It made 490hp/554tq.
I feel a tighter cam would work better in the current combo. Not sure what it would of done in the low comp 440.
