fuel injection systems

i was thinking about putting a edelbrock fuel injection system on my 74 camaro. i have not installed the engine yet (350, .30 over) and i was told that the fuel inection system is great. its also $2100 from jegs. is this worth it or not? how hard is it to install?

there are quite a few diff types of fuel injection ranging from moderate to complicated to install.. but in my opinion, they are FAR superior to carburated.. what type of fuel injection is it and does it come with all associated parts, sensors and wiring

the fuel injection vs carb debate has been raging since the fifties. its pretty much a personal preference. i like fuel injection, so long as you can get a stand alone unit. some people think you can make more power off of FI which is not necessarily true. i do know that a lot of carb guys are swapping over to FI...

it comes with everything. i want my car to haul ass, so. i should be getting around 400 HP now. from what i have. be honest with you, i dont need this system. but it would be a bad ass car.

i like fuelinjection because of its reliability over carb (especially aftermarket) its effiency over carb.. i do think that more power can be made with fuel injection.. but that is solely my opinion and i do not wish to back that up with any evidence of any kind..

I am running a Edlebrock Pro Flo FI unit on my 84 camaro model 3500. I love it. The only problems that I have had in the fuel pumps. They only last about a year when installed under the car. Heat gets to them. When summer arrives, they die. I finally mounted mine in the tank ahd have had no problems since then. I also had to increase the length of the wiring on the ECM to engine. I didn't want to mount the ECM under the hood. Mounted it in under the dash in the stock location. Be sure you order the correct PROM for you cam selection. If in doubt call or e-mail tech service and let them recomend the correct PROM. They are usuallly very prompt with e-mail questions. Good Luck.

PS I got mine from Summit Racing for $1900 for a small block unit

another tip. Installiation is not very difficult. The hardest part is the fuel lines. Also don't install the engine in the car with the intake in place. Too much danger of breaking the injectors or fuel rails

the only problem with aftermarket fuel injection systems is that some of them dont use an O2 sensor, (usually the cheaper ones) they run your engine on programmed settings, which isn't always the correct fuel mixture. i think you should be ok if ya go with the edlebrock system tho, i've heard good things about em. (stay away from holley)

as SAJCLATYON was saying about the fuel lines, you have to run a return line from the fuel rails back to the gas tank, it's not really hard, just a pain in the ass, and most efi kits dont include things like this, or bother to mention them until your ready to install.

you can buy a kit, or do like a i did and get a donor car and use a factory efi system. i bought a wrecked car for a little over $300 and pulled the wiring harness, intake, heads, ecm, distributer, and all the sensors. it's a little harder to do it this way but i was also able to use the front brackets off the engine and convert my engine to serpentine belt, plus if you want to use an electric fan, the harness is already there. i personally prefer factory efi systems over aftermarket ones. the aftermarket systems may produce more power right out of the box, but aftermarket parts are cheaper for factory efi. and gm parts are better quality than edelbrock (imo).

i use an in-line pump and have not had any problems with it. although you do have to be cautious about mounting locations. too far away from the tank will cost you fuel pressure, and can overwork and burn up the pump,(they push fuel better than they pull) and you wanna keep it away from heat.

Most of the Edlebrock parts have OEM part numbers and can be see on the website. I usually get the OEM number and get replacement parts form my local parts man. Cheaper than Edlebrock's prices

Edlebrock unit can run in ether closed loop or open loop configuration. Open loop doesn't need the O2 Sensor for operation

you talk about the o2 sensors messing things up. i have a 2000 mustang with only one sensor, the place i orderer my exhaust from sent me 2 of each side so i only hooked one up, the engine light has been on forever b.c of it. not a big about the light, but will that mess fuel up? i have no cats, thats why i have these
