Should I go \"injected\"?

I'm pretty happy with the mods on my Scrambler. <img src= "http://dosxxs.off-road.com/wwwthreads_images/icons/cool.gif"> 304 with Jacob torquer, 4:10 gears, Detroit locker in rear Ford 9", 35" BFG's, 7 inches overall lift, and a few other goodies. But as I hit a few more rugged trails, and rock climbs, I find myself stalling out as I get closer to verticle (not a lack of power, lack of gas!). So I'm looking at going with some sort of fuel injection system. What's the best, and most economical way to go? I hear that Holley Projection is good, what else is there to consider? I currently have a 4 barrel Carter competition carb. Thanks for input in advance.

Keep on Jeepin'

Re: Should I go \"injected\"?

A fuel injection system will definitely help immensely on bumpy trails and hills. After unsuccessfully trying every trick I could think of to get my carburated 74 CJ5 to run decently off-road, I bought the Howell TBI kit. It completely solved the off-road problem and gave me a little better performance on road as well. If you get the Howell kit you should also upgrade to an HEI ignition. I am very satisfied with the Howell TBI/HEI ignition combination.

Another guy in our club who drives a CJ3B with Buick V6 solved his off-road carburation proplem by installing an adjustable fuel regulator. When running off-road he sets the fuel pressure down to 3 - 4 PSI and the engine runs flawlessly.

Re: Should I go \"injected\"?

Scott,
I have found that the Motor Craft 2150 2bl is the best carb for the AMC V8's in serious rock crawling. I have tryed the Eldebrock(Carter) carbs with the off-raod setup, Q-Jet's, and Holley's with slosh tubes, and none of them performed on the trails like the little Motor Craft 2bl that comes facotry on the AMC V8's.
I have been helping a friend with his new injection setup from Howell and we have had all kinds of trouble trying to get it to run right. I personally would rather try to use a factory chevy TBI setup and adapt it to work on the V8. A guy down the road here has done that and hhis works great with a fraction of the cost of the Howell or Holley Projection.
As far as the way I run my little Motor Craft 2bl on my 360 is to run an electric fuel pump and a fuel pressure regulator, the regulator is set on 2lb's of pressure. It works great for me.
Just my 2 cents.

Re: fuel injected

Thanks for the imput guys. Anyone else installed their own system? Is it difficult? Without any computer stuff on my jeep, I may go for a throttle body unit. Is this a good idea?

Re: Should I go \"injected\"?

I have been running a Holly projection for over 8 years on my 351 ford v8 in a cj3a. it solved all my gas feed problems when going up or down steep stuff. only problem in installation is routing return gas line to tank. only one problem when operating was due to the "new" california gas cleaning out the oxidation in my aluminum tank, gas lines and older rubber hoses. This got thru the filters and clogged the injectors. Injetors can be changed on the trail in about 5 min. Carry 2 spares in case you get some bad gas.

Re: fuel injected

I put a TBI unit on my 258 you can see it here: http://www.neca.com/~crossrds/ I was having problems so I took it off and I am selling it for $700.00 (it is on the for sale board). Turns out the problem wasn't the TBI, I had a clogged catylitic converter. Oh well, I put the BBD back on and it is running fine for now. I think the TBI is best suited for V6 and V8 applications if you fabricate it yourself. It is just a complete headache trying to get the programming done correctly by e-mail.
