    94 tbi 350

    Was cleaning out the truck tonight, found 2 ecms under the seat behind a set of jumper cables. Looked up the number on them. They were both correct for the truck. So I pulled the glovebox to look at the one in it, turns out it was not correct for the truck, swapped them off, runs amazing now...

    94 tbi 350

    Is there a test port on the tbi trucks like on the vortec? If it was fuel pump wouldn't it run lean?

    I've done cap, rotor, plugs, wires, fuel and air fliters, checked for vacuum leaks, also did the 2 wire coolant temp sensor and fuel pressure regulator, truck runs fine when it's cold but rich when it's warm, which makes it idle rough and miss bad low rpms when warm now, it runs like the ecm...

    94 tbi 350

    Did plugs, wires, cap and rotor tonight, forgot my line wrenches at work today so I didn't do fuel filter, will do it tomorrow, runs better but still is doing the same thing, the plugs had almost no electrode left, appeared to be original plugs, truck has 219k miles.

    Haven't had time to mess with it, bought it saturday, doing to start with plugs wires, cap and rotor, it will also die when you first start it if you don't give it done fuel

    94 tbi 350

    Just bought a 94 k3500 srw 350, nv4500 truck, truck revs fine with the clutch in or out of gear but going down the road if you get past half throttle it sputters, doesn't want to pull hills, any ideas?

    "Carb" swap question

    When swapping a vortec to a carb is there any wiring that needs to be done for the fuel pump to stay on while running?

    What size carb?

    It's not going near 6700 rpms lol, this trucks a 5 speed flatbed truck, it's set up for torque, I use it as a daily but it's hooked to trailers a lot and used to haul feed and hay

    What size carb?

    I've got a vortec 350, comp 08-801-8 cam, Promax heads with 185cc intake runners, 2.02 intake valves, 1.60 exhaust, wieand street warrior intake, 1.6 roller rockers, msd street fire intake, I need to know what size carb I need, I have access to a 600 and a 750 but I think the 750 will be too big...
