A lot of riders have already invested in performance upgrades for their stock engine by the time they are ready to move up to a complete big inch engine. Wouldn't it be nice to be able to save some money by using some of those items on your new engine? Well now you can with an S&S T-Series engine for 1999-2006 big twins without fuel or ignition systems. So if you have already added a performance carburetor or an EFI throttle body and tuner to your stock engine, you can use it on your new engine. A carb or throttle body that fits a stock engine will fit the new S&S engine because the heads are specially machined to compensate for the increased cylinder length so a stock length manifold will fit.

• No fuel system or ignition systems included - Use what you already have
• Same quality components and performance as our complete T-Series engines
• Special Head machining - Fits stock length intake manifolds (S&S manifold size 410)
• Stock style breathing system - stock breather spacing and function is compatible withstock and most performance air cleaners
• T series engines are not compatible with HD Softail models
