The ScienceofSpeed 3.5L Stroker Engine increases displacement to 3.5L. Pronounced bottom and mid range
torque increases in both naturally aspirated and forced induction
applications.
For customers who wish to complete the assembly of their own engine,
ScienceofSpeed offers the 3.5L Stoker Component Kit.
The component kit is offered as the rotating assembly (dynamically
balanced crankshaft, connecting rods, and pistons) and separately, an
engine assembly package including all components required to assemble
the engine. |

 |
|
|
|
The ScienceofSpeed 3.5L stroker kit is
available for either naturally aspirated applications, or forced
induction applications (turbocharger or supercharger). Naturally
aspirated applications (up to 480 bhp) use higher compression ratio pistons and lighter tapered connecting rods. Forced induction applications use lower
compression ratio pistons and reinforced connecting rods.
Included in the cost of the rotating assembly is high precision dynamic balancing. |

naturally aspirated applications:
|
Naturally aspirated component kit includes
higher compression pistons and lightened connecting rods for
applications up to 480 bhp. Power gains compared to a factory 3.0L 270 bhp engine, natural aspirated
applications will improve power output to 360-420 bhp when used with
supporting modifications.
Recommended compression ratio:
91 octane (R+M)/2 - 11.5:1 (standard high octane pump fuel)
100+ octane (R+M)/2 - 12.5:1 (race gas & E85) |
|
|
|
forced induction applications: |
Forced induction component kit includes
lower compression pistons and reinforced connecting rods for
applications between 480 bhp - 900 bhp. Power gains largely dependent on supercharger
or turbocharger specifications, typical gains are 1-3x the power output
of a factory engine. Turbocharged applications will experience increase
in compressor response time resulting in increased throttle response.
Maximum recommended power, with supporting modifications, is 900 bhp.
Recommended compression ratio:
Compression ratio varies by power goal & fuel to be used. Typical
range is 9.0 - 10.0:1. Please consult
with your tuner, engine builder, and ScienceofSpeed for recommendations
for your specific application. |

requirements: |
|
Compatible with both C30A and C32B
cylinder blocks. All cylinder blocks must be resleeved to accept the
supplied pistons (93mm final bore size). Cylinder blocks require main
journals to be align bored. Assembly requires qualified technician
experienced and equipped with proper tools for engine assembly including
micrometers and bore gauges for bearing oil
clearance measurement. ScienceofSpeed offers pre-assembled blueprinted
3.5L short blocks ready for head and accessory installation. |
