im putting a 400 small block in my truck. im thinking it will be in the 375 hp/400-425 torque range. not looking for 600 hp.want a torque engine at 200-4500 rpm. right where it can be used without major mods to everything else.im using a vortec l31 heads, a procomp dual plane aluminum intake, comp cams 268h hydraulic cam,218@.05 on I/e and ..455 lift in I/E,stock style dished pistons.shortblock already has been running.stock rods,on summits website i came in at 8.8:1 compression. 600 vacum secondary holley carb. summit headers. i think they are 1.625 dia, and 2.5"duals with flowmaster mufflers exiting in front of rear wheels.i sure love these 400sb engines-wide torque curve at low rpm. gets the old heap movin. what you guys think?
