Where might a guy find tech on that setup? I'd love some fuel injection but I'm way too cheap for one of the aftermarket jobs.
I'm going to start this thread to fill you in on what I did so we don't clutter up the intro thread too much, but I will have to fill in more later because I need to get off the internet and get back to work for a while. This will be more about what I personally did, as opposed to a general TBI guide. I also figure this may be able to help others decide if it's something they want to pursue or go another direction, as these systems are pretty long in the tooth. But there is still merit to them in my opinion, and especially from a learning perspective. Ford was always a few steps ahead of GM on the EFI front, and that left us carb guys without a lot of options for using our 4 barrel intake manifolds and D3VE and older 460 heads when they went to multiport.
In the meantime, GearheadEFI.com and Thirdgen.org are two great resources that I used a lot. Gearhead is for pretty much everything EFI in general, but has separate sections, and Thirdgen is all about TBI and TPI but has some solid info.
TBI works way better than a carb and CAN be cheap, but it can also get pretty expensive, and that money can be a good chunk of a throttle body "self tuning" EFI setup. I'm actually going to get a Sniper soon because I am going to be doing a more powerful build and I want more flow and will need more injector for it. If you are interested in a deal, we can talk about you possibly getting my setup when that happens. If not no worries, it'll eventually go on something else I own or build that it is more suited for.
If you do this, you'll have way more control over how your engine runs, and you won't have carburetor start up or wheeling issues anymore. I went TBI because I got sick of the carb flooding every time I so much as pointed the truck towards a hill. Even the 4x4 Holleys don't really work worth a shit compared to EFI. That said, there is performance potential but it is limited. A stock 454 TBI is 670 CFM which is good for a warmed up mild big block, but not a moderate one. For reference, I'm shooting for a moderate build of roughly 450 hp and I don't feel like this will be enough flow or fuel for it. They absolutely can be wicked up past stock though.
What are the details of your engine build? I assume it has a mechanical fuel pump? You will need an electric with the correct flow to run this but you won't need a whole lot else. You can even use the Duraspark distributor that is on your engine with the TBI controlling timing after locking it out. I'll cover that here too if you're interested with pics.
It's not terribly advanced compared to similar year Ford EFI, but it works alright and is also pretty dang simple. Think of it as a glorified electric carburetor that just happens to have timing control too.
Might be tomorrow before I fill in more.
