    Yes sir Ken thatís the 3400 vin E sad really I said this before but if Gm used quality intake manifold gaskets from day one u would see so many more on the road and less in the yard . If you ask anyone they will bash them for the gasket problem more than anything else their small lightweight compact little motors would have been a positive in People if was done right .

    VERY TRUE. These engines pack a wallop for their size. They were high tech in '94; excellent breathing engines. The LS engines took some of their design queues from the 3100/3400 head designs (they came to be known as "cathedral ports" in the LS). As you say, if not for the LIM, these engines would enjoy an excellent reputation. As it is, if well cared for, these motors are good on oil and gas and power and economy with good reliability if the LIM is addressed with metal gaskets.
