Lloyd Elliott porting numbers

I just got my heads back from Lloyd and I'm pretty excited. My numbers are as follows: stock intake was AVG 162.8 and MAX 216.6 and stock exhaust was AVG 115.5 and MAX 156.4.

Lloyd opened those up to flow MAX intake of 273.1
AVG intake of 196.3
MAX exhaust of 190.8
AVG axhaust of 140.5 cfm

Thanks Lloyd!

What were those max numbers at, and how were the mid lift numbers??

If those max numbers are at .600 or more, you're not going to see that flow unless you're running a very high lift setup.

Having dealt with Lloyd, those max #'s are most likely at .600 lift, and I'm pretty sure he tests at 28 hg. The .500 lift numbers are probably also pretty good though, I'm gonna guess 265/184.
