Like i said i have a 86 camaro with a 2.8 V6 and i want to swap in the 350 GM Goodwrench motor, is it a difficult task? and what would i need to do to make this really work? and also what do i do with the fuel pump it's in the tank, do i remove it or just leave it? I really hope someone can help me out!

 

Look over V6 to V8 posts on this forum. It's covered quite often.

It is a lot of work. The best way to do it is to have a factory V8 donor car sitting beside yours and switch everything over that is different. Basically, that includes everything that attaches to or feeds the engine. If you have emissions to worry about, this is especially true.

It can be done, but figure on a lot of down time. You will end up with a car that is not worth as much as you have in it (but economics isn't the only factor when it comes to cars, right?).

 

yea you have to change the motor mounts too, and front springs because of the heavier engine.

 

If you decide to go with a carbed 350 and emissions are not a concern, you can get a fuel regulator to use with your current fuel pump in the tank.

 

I don't have a concern for emissions and it is a carb 350 new from GM, i was just concerned for the fuel pump in the gas tank how would i work that with the carb 350, and what do i remove and really don't! can you help me out some more?

 

Like flake said, you can use a regulator to step down the fuel pressure with your in-tank pump. You'll need to wire a pump cut-out switch to the oil pressure switch, and some sort of timed relay for starting.

Or, take the in-tank pump out and put a piece of fuel hose in its place, remove the in-line fuel filter, and use a mechanical pump on the engine.

You still have a lot of parts to change out. Did you look over the other posts? Other questions not answered in them?

 

I am having the same issue. Does the electronic pump meet a carbs thirst, or does it exceed it. I was told you can run right thru it, but I am concerned about trying to pull to much fuel and burn up the pump or that the pump will just starve the engine. I have heard the 305 fuel pump is suficient, but is the 2.8? How does this work?

 

i am doing the swap as we speak. theres alot of work, but i have more time than $$$ and I am a mechanic so I dont think its that bad, just takes time. you have to swap the engine mounts, get a different tranny, figure out how to do the fuel system, i am going to keep the intank pump and use a regulator with a bypass on it. then there is the wiring issue, i have cut probably 100 feet of wiring out. theres lot of stuff i havent mentioned but thats a good start.

 

you cannot siphon through the in-tank pump, You either have to remove it as 5-7 said or use a regulator to decrease the pressure to 5-7 lbs. As of now it is pumping about 50psi.
