Big Block Fords are in a class of their own. In an application where raw torque is desirable there is no engine that is better suited. So how do you make a good thing better. Make it bigger. If you have an early block that you can bore to 4.440 (.080 over) and wish to keep the oil ring out of the pin hole (better oil control), then start with the Street Fighter 532. Easily capable of 600+ horsepower and with torque exceeding horsepower is the norm. 532 Street Fighter 4.440 bore - 4.300 stroke - Flat top piston - Cast steel crankshaft - CHP CNC Beam forged steel connecting rods - Probe SRS forged pistons - Dished† pistons available
