Solid Roller camshaft selection those of you running a 408 race application - lobe seperation

Of the six choices you listed, the one I like the least is the Crower.
The others all seem in line.
The two Comps will certainly work fine with the TF springs, since those use high rpm semi-endurance lobes.

If the car will be run at the track with the exhaust system in place, I’d lean towards a 108lsa vs tighter.
