Re: LSA, it is what it is...as it is a sum of numbers..
Many cam companies say that with EFI you need a 112-114 LSA. Does it really matter with EFI? Does the LSA work out to be in that range when everything else is figured in?
I had Mike Lewis spec the Comp Cam in my signature at 112 LSA because I was worried about the Holley Avenger MPFI and power brake vacuum. It is going on the dyno next month to see how well it does. It will be interesting to see how it works out.
