tbi

Hi;
Any advice for an aftermarket tbi for 1964 Ranchero with 289? I see that it is getting pretty competitive price wise. What can I expect for total cost with fuel pump in engine compartment to avoid return line to tank? Thank You, PS I have grown to hate carbs.

Re: tbi

Most carburetor problems fall into two catagories.

1. Carbs that are too big for the engine. I have a 600 cfm vacuum secondary Holley on my 347 that puts out 418 hp. It runs like a raped ape. Go to the Summit Racing carburetor (cfm) calculator on their Web site and you will be amazed at how little cfm your engine really needs. Big carbs are sexy but may actually run worse than a smaller card on a typical street engine.

2. Old carbs that are gummed up, leaky, warped, and/or mistreated by someone who tried to fix them or make them better. Just throwing a rebuild kit on them doesn't always work. Some are just worn out and are too far gone. You can often find factory reconditioned Holley 600 cfm carbs on ebay for under $200. Many of these are just returns, but all have been gone through, rebuilt, and flow tested. They come with a 1 year warranty. Put one of these on your 289 you may find that you like carburetors again.

Re: tbi

You need a single plane intake manifold and pump goes at rear or car next to tank.

Here is the one for my 289

Re: tbi

I have not used a FITech yet but they are very good and readily adjustable. I have used Holley (good), Professional Products Powerjection (ugh, most parts were junk, but it did have a decent computer program) and helped tune a FAST EZ kit (nice kit, programming too simple, doesn't allow you to do anything if it can't figure out on it's own)

Here is a pic of the Professional Products, it's on a 355 Camaro, about 350 hp, TH200R4, and 3.73 gears, RPM intake, and although I did not like the quality of the kit the guy bought, it gained a ton of torque and drivability.



That was when they were really the only modern game in town though, I would avoid them (assuming they are still making them) if someone comes in now asking, I recommend Holley Sniper or FITech.

Iowan, not sure why you said he needs a single plane, I know Yadkin said it fixed issues with his, but I have about 10 different versions on dual plane and single plane intakes. No requirement for a dual plane or single plane with a TBI and in no case did it even matter a bit either way. The TBI system acts like an electronic carb. I think Yadkin had something else going on

The only real requirement I preach is to make sure your intake has a second access point for water. Chevies have places to put the coolant temp sensor all over the motor, often Fords only have one.

When I install a TBI or even port injection on an FE, I have to add a bung, otherwise you either lose your heater, lose your temp gauge, or have to do something funky like putting it in the thermostat housing which makes it less accurate

Of course the picture below is of my FE, not a small block or a TBI, but you can see the added bung

Re: tbi

The shop I work with , if there is problems with fuel distribution and a tbi its the manifold, open single plane works.

Well, they must like swapping intakes over tuning. By the time the fuel from a TBI passes the base gasket, the motor doesn't know any different and unlike a carb, it doesn't need the vacuum signal to make the circuits work.

Re: tbi

Hi;
I have been very busy and I am also very slow on the internet navigating. Thank you all for your input on tbi vs carbs. I guess I just kind of want to install one of the after market tbi systems. I'm not a race guy and have, please forgive me, mainly been a chevy person for most of my life, after starting out on 1950's fords post flathead. I'm having fun with this Ranchero and have learned a lot with the drivetrain changes I have made. Thank you once again for the posts. Carver

No worries Carver, happy to help. As you pick, think about two things. 1 - already mentioned, where the coolant temp sensor will live, and 2 - think about your return system and fuel pump

FITech sells this funky reservoir to allow you tto run a stock pump then a high pressure pump. I really don't like them. If you are going to spend the money, plan a full return line to the tank and set up a nice in-tank pump (way better) or good EFI pusher pump close to the tank. In the end it will be quieter, perform better and more reliable. FYI - My Mustang runs a dual pump Lightning pump setup with aftermarket pumps, way overkill even for my 489, but modern car quiet and ready for a big supercharged motor later

Re: tbi

Here's what I like for a stockish small block, I couldn't find it the other day but FIteck is the only 2v I've seen that wasn't a kit made from rebuild OEM parts.

Holley has one also.
