Ave you done the tb heater bypass yet? Supposed to b worth a couple hp

 

Throttle Body heat bypass? What's that? And where can I get the L67 D576 coils at cheap I saw they're $76 a piece. Lol they come on any cars stock I could pick up at pull a part.

 

So do you think my stock setup 3.1 0-60 in 7-9 seconds is pretty sweet. Seeing as I'm running 240+ hp and 270+ torque with all stock parts just tuned perfect.

 

Yup . Throttle body bypass is where you block coolant from going through tb=cooler intake charge. 97+ buick ultras, 96+ rivieras, 98+ regal gses, 97+ gtps, 04-05 monte/impala ss would all have l67s

 

How do I go about doing that. Instructions please! It sounds interesting.

 

Take a piece of 3/8ths fuel line and loop the two nipples on the rail under the tb that hooks to the heater core.

 

I just saw your location. I used to hit up the upullit on watkins. They ALWAYS have something l67 powered there

 

I go to the Pull A Part over there in the wear hose district they keep 30 3.1-3.8s bare minimum. So I just loop the fuel line around the TB or an extra piece and hook it too a loop under it that connects to the heater core

 

I just noticed your location. I go on vacation every July for the first 2weeks in Van Buren. This summer maybe we can meet up and you can take a look at my Monte haha it should have even more done by then. I love showing people what the 3.1 was meant to be. As long as you make every part precise this engine is one of the best you can ask for.

 

Yeah im always down for new friends . My old 3400 never failled to start,even when it had problems
