1/2 ton status
the engine i built for my k5 was as follows
400 2 bolt bored .020 with kb d shape dish pistons, 5.7 rods (350 length) stock cast crank. dart s/r torquer heads with mild porting in the bowls, comp was set at 9.5:1. comp cams 260h flat tappet hydraulic, 1.6 roller rockers, dual plane intake and edelbrock carb. the engine pulled very hard to 6k rpms. the torque was powerful enough that a 12 bolt didnt last long, neither did a t350 trans. with this engine my blazer ran mid 14's in the 1/4 mile with 35inch bfg's.
