The new LZ9 3900 features Variable Cam Timing , a new feature on a pushrod engine, roller rocker arms and has a variable length intake manifold . The dual intake runners (One short, one longer) improves intake efficiency across a broader RPM range. It produces 240 hp (179 kW) and 240 ft·lbf (332 Nm) torque, with a wide torque curve . 90% of the torque is available from 1500 rpm to 5500 rpm. That's gonna be allot of work getting that all...

Also, the block is originally from a 1995 3.4 that had been re-converted to a 2.8l - Any help will do me wonders...

Yeah that is something I WOULD have done, but in all honesty I am happy with my 2.8 and it's fuel economy

I took one plug out. and tried it but it just did the same. i am going to go pull all the plugs in a hour and check.

The Model 220 TBI commonly found on the 2.8 has a constant bleed feature in the pressure regulator that relieves pressure by itself. Not sure how quickly it should drop however.

I switched my 86 to carb because the old owner thought ripping all the wiring for the O2 sensor was good for Horsepower, Needless to say my carb setup gets like 150 to a tank and never starts in the winter by it self, Also like to stall when it actually runs in the winter
