3.4 DOHC
91-95 3.4 DOHC motors are all alike other than a few updates in 94 for sequential fuel injection. 96 was the first to get new heads and intake/exhaust manifolds, with a domed piston. 97 was the same as 96 other than the 33mm lifters vs the 35mm lifters that are sold here. For more information on the LQ1 motors, please check out the 60DegreeV6 Forums for the DOHC motors.
