that intake he is running isn't a high speed intake its made for low end torque ( tops out at about 5 grand on power ) , but as long as you watch the plugs and be careful when you shoot the juice as if you do it in the lower gears you can bend the factory rods .when I was at the NOS seminar with Mike Thermos he reccomended only giving it the juice in the upper 2 gears with factory rods, never out of the hole . also if your running the hugger headers ( tubular exaust manifolds) they are restrictive and are a little better than stockers in flow style , some guys are using the old vette rams horns with sucess , or switching over to long tubes and oval exausts for clearance ( spintech.com ) . and the long tubes ( 41 ") really wake the motor up. and also see what type of o2 sensors he has , NTKs or densos are the most accurate for tuning .
