Features & benefits

Fuel injected engines will require recalibration of the fuel injection system - the S&S VFI modules and closed loop sensor kits are highly recommended
Stock 88" cylinders can be bored from 33/4" bore to 37/8" to accommodate the S&S pistons, or a pre-fit S&S cylinder and piston kit may be installed
S&S stroker pistons, which are sold separately, are available in all standard oversizes
Engines with factory 95" kits require piston fitting for the correct oversize only
Since stock cylinders are used the engine height remains stock
This kit is engines with internal balancers only
Stock or S&S cylinder heads can be used
