    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?

    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?

    Matt, So do you send him a stock ecm like a 747 and he modifys it? If so that would nice.

    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?

    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?

    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?

    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...

    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...
