The 351C engines that we do keep to a 3.850 stroke for a better rod angle and piston design for the street and longevity. This makes a 393 to 396 depending on the bore. I would use the edelbrock head with our CNC program on it. This engine makes about 525HP and 525 ft/lbs of torque. We do thes engines for about 10,000.00 to 11,000.00 depending on options. This is with a 4340 steel crank and 4340 H-beam rods and hydraulic roller camshaft. The 351C style engine is a little more expensive to build than the Windsor engine. Thanks, Keith
