What makes a cam "lope?"
Low overlap (good idle, "gallop"): Cha-cha-cha, Cha-cha-cha, Cha-cha-cha, Cha-cha-cha
High overlap (lumpy, lope, sounds like it runs like **** and gunna die): Blub-BLUB-blub-blub, Blub-blub-BLUB-Blub ... BLUB-blub-blub-BLUB
At least, that's the way I understand it. I had a higher overlap Gen 1 383. My engine builder called it a "3/4 race cam."

Sorry for reviving an old thread but im pretty sure there is alot of misinformation out there. Correct me if im wrong
Overlap= (intake duration+exhaust duration/2)-(lsa x2)
For example: a 224/224 114lsa is
224+224=448
448/2=224
114x2= 228
Therefore overlap= 224-228
Overlap=-4*

Tooley has this truck cam that I find very interesting. I'm willing to say it sounds bigger than what it is.
Specs....
224/230 .553/.547 111+2
On a 111 it gots to be choppy but notice the low lift...

It may have a lower lift, but notice the duration. Combined with LSA I'm willing to bet you're right. Do you have a clip of it running?
