• Stock style breathing system; compatible with stock and most performance air cleaners
• Includes Super Stock heads, crankcases, high flow oil pump, cam cover and easy start cams
• Specs: displacement 124″; bore 4-1/8″; stroke 4-5/8″; 640 cam; piston type forged flat top; compression Ratio 10.8:1
• Black Edition includes all the features of standard S&S engines, with gloss black engine covers in place of the standard chrome covers
• Cylinder heads on T-Series long block engines are 99-05 style. Owners of 06 models will need to purchase a set of 99-05 style, offset intake flanges.
• Cylinder heads on these engines are specially machined to compensate for the non-stock cylinder length. As a result, they are compatible with manifolds and throttle bodies with stock length intake runners. In addition, the breather vent bolt locations have been adjusted so they are in the stock location, so stock style air cleaner back plates will bolt up to these engines.
• Made in the U.S.A.
