Crazy Idea

2500sierra · July 13, 2009

i always like to drive something different and i also hate having a computer telling me and my engine what to do. so......

the only time i prefer fuel injection is a cold morning letting it idle to warm up. other wise i have no problem with my caveman carbs.

not serious about this yet, but tell me what you think.

And i know my tranny wont work right with this but if this happens then a manual will too.

If your willing to just spend money for the heck of it and loose performance and fuel economy let alone drivability go for it.

do you really think i will loose performance and fuel economy with the right sized carb? I had a 383 with a 600 on it and i got near 15 on the highway doing 65

Fuel injection is a precise metering of fuel to each cylinder controlled by an ECM with many sensors on a carbed system the amount fuel is dependent on barometric pressure and the result is poor mixtures and distribution.

wow, just wow.

uhh is there a problem? you would care to explain?

I hate to have to disagree Here is my 2 cents. There are many pros and cons to the idea First off performance wise and drivability will be fine. I can tell you right now Some of the older carbureted vehicles could blow todays fuel injection out of the water.

You honestly will see a drop in fuel economy from a carb remember what fuel injection was designed for to be more economic and advanced technology. The motor itself will probably breath better and dump more fuel so performance will increase. Its a neat project and i would like to see it done.

Its all up to you what you wanna do in the end you gotta do what you want to do. You will never beat the throttle response of a nice 4 barrell carb. But you wont enjoy trying to crank it on those cold winter mornings.

In all its a nice project keep us posted.

I personally would stay with fuel injection

Alex,

Like you, I've come from a mostly carbureted engine background. While it may be more comfortable to you to work with a carbureted engine, I'd still recommend sticking with EFI. You can make it do all the things a carb can do and much more. If you're willing to learn a new skill, possibly taking some of the EFI tuning classes is for you. I haven't done it, mostly because of the lack of motivation and interest to invest the time. Besides, I have only one truck that I would use it on and it's my daily commuter and I just want it to drive nice.

Frankly, my opinion of the Holley carb is pretty low. It's a very crude carb with overly simplified circuits. They work good for WOT, but lack sophisticated transition circuits for a street/road car like the Quadrajet, Webers, Solex, etc..

Stick with the EFI.

ya i guess i should stick with EFI since a carb would already be a step back. I just thought it would be pretty cool to pop the hood and see a big chrome circle air cleaner, but then i couldnt participate in which CAI is the best threads .

well if some large part of my fuel injection system ever goes out i will definatly consider this, but i guess not now

It would be sweet to learn how to tune fuel injection, ill be going to PSU for college so hopefully i can learn a little more about it there.

There is a ton of things you can do With Fuel injection system PM me if you want to know a few I myself Grew up around carbs but with the change in time comes the change in technology.

I think the carb would be a nice project truck though However i agree dont get a holly carb There are not what they seem to be.
