put one of these cams *voodoo 60102* in my 350 bored .60 over, performer rpm intake, headers, 2.02/1.06 heads, n a holley 650 dual feed.... call the techs at lunati... basically tell them how u plan on driving and that u may want a voodoo and they will lead u in the right direction.... if ur looking for a "rough idle" or something lopey, this isn't the cam for you, they are engineered to run smooth, but i will say that i have great power all across the board...... this is my daily driver el camino too
