For the second round of our small block Chevy testing, we installed a parts combination that upgrades our GMPP 290 hp 350 dyno mule into a late-model Vortec style small block.  This package includes Edelbrock’s new Top End Kit with 170cc E-Tec aluminum heads, Performer RPM Air Gap dual-plane intake, Edelbrock hydraulic roller cam and all required fastners and gaskets.  To that we added new hydraulic roller tappets from Crane, shorter length pushrods from Summit Racing and a set of Summit 1.6 ratio roller rocker arms.  We topped it all off with an Edelbrock “Thunder Series” AVS carburetor.  This parts combination raised performance throughout the curve delivering a peak 411.9 HP @ 5800 rpm (121.9 HP gain) and maximum torque of 419.8 lb/ft @ 4500 rpm (93.8 lb/ft gain).  The cost of this particular combination is $2770.75 meaning each additional pony cost us approximately $54 bucks.
