big lsa's vs. small lsa's.....

which makes more top end power -which makes more midrange torque-powerbands,etc.- back up opinions with research too.

heres a dyno of the same setups of 2 B1 cams and a T1 cam; B1 is 221/221 .558/.558 114 and the T1 is the same on a 112.

the blue one is the T1. im a 112 guy myself, but for my custom cam i might go with a 113.

thanks for the info jrp:D

well according to that graph the 112 made more torque down low-so tighter LSA's are better for power wider LSA's better for emissions? correct? wider shifts the powerband up the rpm range?

As a general rule, the lower the LSA, the more your cam will lean towards top end power. The higher the LSA, the lower the power. This is why stock cams usually have high 116-118 LSAs, and race cams are usually lower 108-110 LSA.
