Ford SB 289 302 Windsor 5.4" 4.000" 1.090" 0.927" Flat Top Forged Pistons while Cleveland/Modified applications use precision

while Cleveland/Modified applications use precision laser-cut steel for a factory-style fit and finish

They feature bodies and / or secondary towers and feature brass secondary contacts (except direct fire coil on plug applications)

reduce stretching and prevent the belt from slipping

They are made of aluminum and feature a natural finish

Couple this Hi-Ram intake with the high flowing Ford Coyote style cylinder heads has outstanding potential for naturally aspirated and forced induction applications
