    so as some of you have noticed by now my frame sitting in my driveway is lacking a few parts..mainly a power plant. although it's tough starting with out an engine i can look at this optimistically and say it gives me a chance to choose what kind of engine i want to use.

    anyway the debate is between the oddfire and the original L head. now while i would probably go with the first one i could find either free or very cheap,since i was thinking it would need a rebuild anyway, this is more of a pole of opinions rather than a clear cut decision.

    I've read some of the extensive dauntless information on the main page of this website and really like this V6, cons would be getting it to fit under the hood of my 3a amongst others. but fitting the engine is within my realm, i could definitely drop motor mounts or weld up some kind of solution.

    i haven't been actively looking for one of these V6 blocks. so if you would mention if you are looking to unload one of these types of engines that would be cool.

    i see that the two engines are about the same weight, I've heard a primary shaft in the transmission is specific to either V6 or 4clinder. probably a different radiator. I've never done this before, but if you could grace me with your opinions or experience it would be much appreciated.

    thanks a lot
    Paul

    Paul,
    I'm trying to do the same to my 2A. A friend gave me a CJ5 w/ a 225 but in has a cracked block. I found another block on EBay but it was also cracked.
    There is an '80 or '81 Buick Skylark at the local U-Pull It that is complete for $198.00 that I may get. The good thing about the donor CJ5 is itis already connected to a T-90 so it should save me a bunch of money on parts.
    If I go with the V-6 there is a possibility I may have a spare F-134.
    Keep me posted on your progress.
    Tommy

    i know, sorry for using the word "classified". but the intention of this thread was more information or expirence with these two engines, and if one of the responders had a spare or one for sale, i figured two birds with one stone.

    I've driven both. There really is no comparison. There is a good reason so many 4 cyl Jeep engines have been swapped out over the years...With the 4 cyl, you will find yourself in situations, on and off road, where you actually say out loud: "If I just had a bit more 'umphf' "...!! :D
    You'll never say those words with the 225... R)
    Find and install the V6, it will be worth whatever it takes. :beer:

    This of course is JMHO... there will be plenty of different views... and what do I know, I don't even own an ECJ5.... R)
    Take it for what it's worth ;)

    As you can tell by my sig - I much prefer the V6 in the flatties. Been doing it a while and the fit is not as bad as some might think. To me it comes down to the plain and simple HP to Weight ratio. The 225 wins hands down. If you want more info on tips and trick, just ask. Several of us are real fond of the swap in the flatties.

    thanks for the response, that's what i'm looking for. experience driving either motor, since otherwise i wouldn't know untill i already had it on the frame.

    yeah that would be great, it's good to hear they do fit under the hood. i haven't read much but what i have says they are difficult to time, is there a lot of maintenance or if it was a rebuilt motor would it be about as cumbersome as any carburated engine?

    It's like anything else - if you take a little time to do it right, there is minimal maint to keep it going. I have gone through everything in the 51 except electrical, the Steering column (did the rest), and the fuel tank. All of which the PO did. The only thing that broke on me wheeling this year is the fuel tank - now that's getting done.

    I'm whit Jim - it's not real hard to put the V6s in the flatties. My variances come down to how I want it now.

    sounds good to me, glad to hear they aren't that fickle if you do it right. how about the radiator, i have one the came from a 134 setup, is that good enough or should i look for something else?

    I need a different air cleaner (I have the stock one but don't think it will fit) but here is a pic of my 225 in my flattie. I LOVE the motor. The only thing I hate was cutting the inner fenders, but these fenders were not the best to begin with. I plan on paintin g the motor all nice one of these days... want the outside to look good first.

    The stock L-head radiator is cooling it just fine after I got it all cleaned out.

    i'm not so sure about it making that dramatic a difference off road. i've never had a problem with any of my 4cyl jeeps offroad not having enough power to go places.

    the real bonus of having the 225 in the flattie shows itself when you want to drive down the road over 45mph. the buick has enough power to go 65-70 with plenty to spare. definetly has some get up and go whereas the L head feels underpowered at just about any speed over 30...

    my 53 3a has a 225, warn overdrive and 5:38 gears I can cruise down the highway at 60 and still pass if I want to. it makes a very nice ride to where I go Four wheeling with it. the 4cylinder just will not do this. when off road it only gets better.

    With that said, I would put in what you want, but the v6 is the way to go if you want to keep up with traffic and be able to motivate when you need to when 4wheeling.

    I have used the 4 cyl rad for years. You will need to make sure it's in good condition and have it set up right. This last winter I moved mine forward an additional couple inches in the '51 (with the SM465 swap) so went with a custom 4 core job I had made. Depending on how much you want to swap out, I also liked putting a 2" body lift on. Still had through floor pedals that I knotched the floor for, Saginaw was not an issue for the column. That allowed me to run a 'real' nice K&N air cleaner for a change.

    I am getting ready to put a 231 in a '49 I have here (next in the shop), I have all the parts together (or 90% at least). Should be starting in a few weeks. I can try to help you out with yours as I go through another one of mine at the same time if you want.
