vortec to ls1 manifold? Has anybody done a vortec truck manifold to an ls1 camaro manifold swap? What all is involved in this besides the manifold and fuel rail? can the same sensors be used etc,etc. need any help I can get please! thanks
The vortec motors are a completely different design (they are regular old sbc's) then the gen 3 motors. The manifolds are not interchangeable. What are you trying to achieve?
To change it over you will need the basics like you said. You may want to check over @ ls1truck.com and see what they have to say. I know the LS Vortec uses a different injector than the LS1. I would think the injector driver is the same but make sure. It's nothing a custom program couldn't fix I'm sure if there is a problem but doubtful. Also on the Vortec motors how do they regulate fuel pressure? Is it on the rail or elsewhere? May have to use a 97-98 fuel rail depending. That's about all I can think of at the moment.

thanks kossuth! I plan on getting a 97 vette fuel rail to mount the regulator somewhere on the truck, and was hoping i could use the same sensors and stuff from the old manifold to the new one. I imagine it kinda basic but would rather hear from others before I run into problems.
Duh, I wasn't even thinking about the late model motors. Chevy has been using the word Vortec since at least back in the 1980's. To me it doesn't mean anything to me.
Anyways, I just did the swap you are talking about and it wasn't too bad. The map sensor is different (but uses the same plug) and the evap system is a little different but again uses the same electrical plug. I used a 98 vette fuel rail because I needed a return line and the lines on the rail interfere with the truck coils. Nothing a little manipulation can't fix (read: bend the crap out of it to make it work) truck injectors won't work-they are too short. The injector plugs are different between the two. Thats about all I can think of right now

a few things you will run into:
the steam lines will interfear with the throttle body when using an LS1 (f body) intake. also, the belt routing will not working with the LS1 intake.
the upper radiator hose comes out horizontal on the Fbody water pump, and comes starait up on the truck water pump, you maybe able to get by, but I know the belt routing will not working with the LS1 intake.
I have a 6.0L in my 67 chevy pickup, using stock belt routing. I tried to put a LS1 intake on it and it will not clear. I'm not sure if stock LS1 (fbody) accessorys will fit on the 99 up trucks..have never looked into that.

I have used the stock LT1 pump from a 1993 (power rack) on my 1962 impala, which used a valve and cylinder for power assist, and I used that same pump in my 67 chevy pickup for power steering. with no problems. I later installed that same engine and power steering pump into a 3rd gen F body, wich uses the old type steering box, and have had no problems with it at all.
