408 build suggestions

This is a good candidate for a custom cut cam to match what you want for driving , or have an expert engine builder spec one for the best characteristics and ultimate power. 408 cubes need extra overlap for best power. Brian at IMM spec'd a mother thumper cam for my 408 street motor, [email protected] in t, 249 ex with a 107 LSA.
Calculate the overlap for the Mother Thumpr ( middle cam of three thumper Comp cams offered) and look at the choices you have looked at. A narrow LSA. Or a dual pattern cam to provide the extra overlap will perform best.
