Hi everyone,

So I have a carbureted 350 engine in my truck. I want to make it fuel injected but I don't want to spend 2800$ on a EFI kit. My plan was to convert it to a L31 vortec, I have a good 4 blot engine and their basically the same thing So what ive done so far is I bought a intake manifold and the wiring harness from a running L31 from the internet for under 300$ (used) the harness is in great condition and so is the intake. I got rid of the black box and did a 0411 on the harness. The issue I have is this; I have a manual valve body 700r4 in my truck that you obviously can't connect to the harness. Since there won't be a transmission hooked up to the harness will the engine run badly or even run at all? any advice?

thanks
