Technical Motor trend explain LSA

Motor trend engine masters did a video dyno test explaining 3 different LSA on a camshaft on a 440 mopar,very nice. 108,112,and 118 shows difference of power curves

 

Cool
What were the results?

 

Peak HP about the same, 106 started out with more torque all the curves were equal amounts lower,but you need to see the dyno sheets or graph.

440 Magnum had lsa of 115 and a very noticeable idle. I wonder if 106 on the original duration would be streetable. Did they look at idle or vacuum?

 

Roller or flat tappet
