    Tbi conversion help

    I think I will keep the 747 harness and modify the vortec intake to work on the early heads. It's hard to tell how long I keep this truck, but if it's long term I will most likely go with megasquirt or maybe even drop an LS engine in it.

    I'm buying another 350, an earlier one with a square bore intake. How do the square bore to tbi adapters work? Will I have any problems with it?

    Tbi conversion help

    Kinda bad news, I got the engine that I have had in storage out to go over it. Pulled a head and 2 cylinder were full of water, they could of been like that for years. They are way past the point of honing and need bored. I'm going to use it as a core at the junkyard. So I will be getting a...

    I honestly have not even pulled the harness out of the box. I'm going to get the engine out of storage and into the garage this week and want to be prepared. I did find a diagram for the 747. That's great that it still has the fuel pump relay, it saves me a little bit of work. Everything else...

    Need a little help, I've searched with not much luck, but I need a wrong diagram for the 747 ecm. I mainly need it for the 12v + , grounds and the fuel pump wires. Any help?

    Will you need to run a regulator with a aftermarket pump?

    Questions about selftuning efi

    Im with SkinnyG, go for Megasquirt. Ive done multiple installs with great luck. Its very simple, and there is a ton of info out there on how to do it, especially for a SBC. There is even a feature that will help you dial in your tune using a wideband O2. Once you get it in the ballpark and have...

    Ok. Well I really have no use for 2 tanks, so I will most likely eliminate a tank when I do this. A quick glance at rockauto looks like I will have about $120-$150 in a new tank, sending unit, and pump.

    I think for now I will take the gamble with the injector. That is above option rather than buying a new one if I honk it's just clogged. Can I drop a later sending unit in the early tank?

    Tbi conversion help

    Ok, I haven't priced out injectors, are they expensive? I'm going to use a inline fuel pump for now, when I switch to in tank pumps is there a factory switch option for the dual tanks?

    Tbi conversion help

    Viktor is going to hook me up with a harness and ecu. I'll check everything out on the stand before I drop the engine in. The engine has sat for 10+ years in a garage. I will pull the valve covers and oil pan just to check it out. I considered buying a throttle body, viktor recommended I freshen...

    I like that much better than trying to mess with burning proms and sourcing the correct ecu. Should the ignition and everything else plug into the current engines components?

    Tbi conversion help

    I contacted Harris, and a few other chip burning shops. I explained the situation and mentioned that I will most likely need a 7060. I somewhat frequent on thirdgen.org, so I did a little digging over there. All of those guys buy a cable and burn their own chips. Which is way more than I want to...

    Tbi conversion help

    A few questions, Can I change the pin out on the harness to work with s 7747 and somehow add an ecs? Say I go with a pcm, how hard is it to find someone to burn a chip(or program) the pcm to now throw a code because of the missing trans sensors? If so, how much will that cost roughly...

    Tbi conversion help

    Worst case scenario, I pull the intake and throw a carb on it. I just would love to keep the tbi for drive ability. The plugs to the computer are brown. Both the same color. (Assuming I am looking at the correct plug) Will I be better off leaving the exhaust manifolds on the engine? Thanks a...

    I ran out and took a look at it. I don't see the esc module. It does have this on the passenger valve cover, it looks like it has something to do with the egr. The casting # on the block is 14093638, which from all I can find it's a 87-95 block but that's not helpful. EGR will have to stay...

    The donor truck did not have a manual trans. It was auto.

    Tbi conversion help

    I'll have a hard time finding the specs on the truck because all I have is the engine and harness, the cab and ecu are long gone. I'm sure the harness will be differentfor an auto, it would have more connections to the trans right? I found quite a few 1227747 Ecus on eBay. So it will physically...

    I am going to drop a complete 350 tbi engine into a 75 c20 with a 4 Muncie 4 speed and I have a few questions. I'll state some of the facts first. -Engine is from a 91ish (I will verify the year) 2500 4wd auto -Engine harness has not been cut, every plug is still intact -flywheel and...

    C20 transmission

    I agree with that. Saving a little now may cost me a lot down the road. Money and headaches. A family member just told me they have a freshly rebuilt th400 that was never installed. It was out of a 1st gen camaro, so I don't know if the tail shaft length could be different? Another option...

    C20 transmission

    I am buying a c20 without an engine or transmission. I have an early 90s 350 that I plan to use in it, and I am trying to decide on what transmission I should go with. I know the truck originally had a TH400, but would it be a bad idea to use a 700r4 in it because I may tow a car trailer with...

    2wd to 4wd

    After talking to some local square body guys I think I'm going to part this truck out and run the c20 I have for now. Maybe some day I will find a k20.
