LSA for a Carburetor Hi, I worked with PML when we created the GMPP line of LS Carb intakes.
We FOUND a difference in LSA requirements when EFI/Carb choices are made.
I agree with BT about your lobe duration/lift AND state the LSA is more directed to EFI.
My specification is the same Lobe with a 108 C/L.
The reason is that a carburetor fitted to the intake manifold has a great amount of Tau fuel or "wet" port walls.
The FIX is to fit a camshaft with greater Overlap that will "clean" the intake port walls.
