3500 Sportsman Upper Intake

Product Information

Using a 3500 upper intake on a 3400 improves the powerband of your engine, and porting the manifold improves flow significantly.  This manifold is matched for use with either the sportsman or competition series 3400 lower intake manifold.  Unlike the competition series, the ports are straight cut, not angle cut and radiused.  If you want the most flow from your 3400 engine using the 3500 upper, the competition version is what you want.

This is not a simple drop in and be done upgrade.  The 3500 manifold uses a different throttlebody bolt pattern, and WOT-Tech offers 3 solutions.  The first is the TCE billet TB adapter that uses the familiar 3400 bolt pattern and works perfect with the TCE billet 62 or recommended 65mm Throttle body.  The second option is the LX5 throttle body adapter by 60 Degree Inclusive which allows the LX5 65mm TB to be adapted.  This is more difficult with no available cable bracket but the DIYer can sort this out for now.  The last option is the TCE 5.3/Northstar TB adapter, which is 75mm.  This is a bit much for streetability but for those that want to have a dedicated race motor, this setup could be for you.
