    I would look for around 250 hp or thereabouts. Plenty for a 225 and it will help keep costs down and reliability up. You start going much more than that and you are constantly fiddling with it to keep it running at it's peak. A good 4 barrel carb and intake, good headers, a mild to medium RV cam, and a really good quality rebuild with balancing and blueprinting should net you in the ball park. I know I could get more out of mine just by changing carb and intake, but that dual jet will actually run on it's side (don't ask me how I know :) ) so I keep it for the trails and what not. Really works well, for a carb.
    Regarding fuel pump, I had to run an electric Holley blue pump with a pressure regulator on the race motor as a mechanical, even a good aftermarket, simply couldn't keep up with fuel demand.
    On my CJ-5 I run a stock type mechanical pump with no problems, but carry an electric in my junk box I can plumb in just in case. Nickmil. :rofl:

    Nope...quiet when all is well, only hear it when low. No fuel gauge here.

    Well, got a call back from the machine shop. 250 bucks for the balancing. So 550 for total machine work. How does this sound?

    I realize I am reviving a very old thread, but it seems to have alot of good information and is very relevant to my current project. I have a 67 CJ5a (currently being reassembled) and a spare 225. I recently started collecting parts for a mild performance rebuild of my spare 225 and have the following so far:
    Offenhauser 6035DP 4bbl manifold
    Buick HEI distributer from an oddfire 231

    I'm trying to decide on the carb, either an edelbrock 500CFM manual choke, or the holley 390 CFM manual choke (I'd like to have my choke cable connected to something:)

    I plan on a small lift (1-2") and running 31x10.5 on my 8x15 2.5" offset wheels. The jeep will mostly be used for cruising around country roads and the occasional surfcast fishing trip to the beach. I want to keep the jeep very drivable and don't plan to change the brakes or steering, I'm also thinking about a custom 2.5" single exhaust through a flowmaster 50 series out the back. My CJ7 with a a vortec chevy 350 has corvette shorty headers and a custom 3" single exhaust through a 50 series sounds awesome. Any comments would be appreciated. you can also let me know if you have a decent used carb that will fit my needs.

    Thanks

    how about the holley 470 truck avenger?
    how about an electric fan? itll take quite a few hp off of the motor and put it to the rear wheels.

    The electric fan is a good idea, the truck avenger carb is a bit $$, I would like to continue my trend and find a good used carb that will work well.

    I believe that is the one that most of the guys here that are running or wanting to run a 4bbl are suggesting.

    That's a good choice from what I've read.

    I'll keep my 2G though, thanks. I can still tear up a T86/D44 2 piece with my V6 and it's just cammed with headers. ;)

    Man o man, I can not believe this thread is still around here. Too bad I never got around to building that motor. Oh well, Sandhill mike did have it, dont know if he still does or not.

    I've got a 225 that has a dyno slip for 376 HP - I've calmed it down some since then, but your lookin at the right parts. I have run Edelbrock 500's, Holley 390's, and now the TA 470. The TA is the best of them all so far (stopped me from digging too deep in FI).

    For Buick power there's no place like http://www.taperformance.com/ They have everything from mild to wild here. View attachment 16841 I think one of the members runs a Ken Bell V6. Maybe they'll chime in. Plus look in the Tech section here. There's info on cams, 4 BBl swaps, and such. Ignition upgrades are numerous; pertronix (w/ current dist), MSD (w/ current or aftermarket dist), stock GM HEI, or DUI (Davis Unified Igniton) HEI, all of which are used by one or more of the members here. Good luck on the project.:v6:

    That would be 'me' Rocky ;) Unfortunatly, most of the Kenne Bell parts I have are not available any longer. Will have to pic and post them one day. The valve train is real 'purty'.

    Renegade II on this board out of MI has a hot little V6 in his rig.... FI the whole deal. I think it was based on a 231 block though. I think it was bored out to like 4.1L or something as well.

    I am planning on doing a rebuild myself, so I called the guys at TA Performance and asked them what they normally do for the 225 in a Jeep. I was told to bore it out to a 231, use 231 heads, even fire intake, and use Buick 350 pistons. Nothing about carbs or headers, but I'm sure they have something they do. Sounds like I might as well get a 231 instead:?
    I hope I'm not hijacking this thread, but my question is, with a rebuild that can double the HP, what do I need to do to the rest of the drivetrain? I'm not sure that the 3 spd will work too well with that much power.

    Glad this thread was brought back. I never saw it before and it has some great info. Since I have three Dauntless powered Jeeps, it is very relevent. Has anyone ever tried the Motorcraft 2bbl carb with the 1.08" venturis, on the Dauntless? I put one on the 258 in my '77 CJ5. The difference was night and day. The MC2100 works very well off-road, too.

    Regarding putting a 231 in, in place of a Dauntless. You don't (easily) have the heavy flywheel. You can balance it to match if it's an even fire. Why bother boring it to 231? Just redo the water passages, and use the 231 top end if that's the case and a good cam.

    Regarding the 2100, I know ljspop had one on his 225. Most of us aren't unhappy with the 2G though. It's as good off-road as the 2100 and can't be improved upon much unless you go 4BBL or FI. JMO.

    The edelbrock 1404 manual choke 500CFM is very affordable, has anyone had good luck with them? Do the factory accelerator, choke, and throttle idle set cables still work with it? I'm not looking for a race engine, just a strong tourquie fun powerplant I can lug in 3rd gear.

    I had issue with the Edelbrock 500 - just could not get it dialed in and I really like them. It might have been the alt I was trying to get it to work at. Since - I have really liked the TA 470 and got one for @315 off Ebay.

    Warloch,

    do you run a mechanical fuel pump? Can you still use the dash idle control cable?

    Yup - Mech fuel pump. Don't know why you couldn't rig the idle control with a linkage tied to the throttle side.

    how about the choke, can you remove the electric choke and hook up the cable to make it mechanical? I just want all the knobs and cables on the dash to work.
