    so the 500 is going to a new home tonight to power a Suburban.... so either a 400 or a 6.5td.... I love diesels in trucks, I really do, but I'm not so sure about diesels in open top vehicles - yes, it'd get great mpg - but a 400 with vortec heads, some kind of edelbrock carb, TBI, or propane wouldn't be bad enough mpg to warrant the stink, not to mention the double, triple or even higher initial buy-in cost.... decisions, decisions... thoughts?

    likely, I'll punt - put a NV4500 behind the 400, and someday come up with a diesel solution... I have some big suspension plans for this, and derailing the project with a diesel swap could relegate this to a spot next to the Fiat (which got stopped on wiring, that I've 1/2 solved, but now have no time to finish).

    The 400 for sure. Why focus all your money and time and patience for a project then run out of gas to finish the rest. The 400 will be plenty to power the fj(as you know lol) and in the end you are gonna have a cool fun toy anyway! Plus I'm biased to gas engines. I simply hate how loud diesels are.

    Some decisions to make - input is welcome.

    a picture of the transfer case


    if you'll notice, the cover is missing and what they did was "convert" it to 2wd. The rear housing is gone, internal gears are gone, brake, .... it's just a housing someone pressed a bearing into. I always thought this one was odd because the rear differential was in the middle (they're offset right) on all FJ40s. Someone put a toyota pickup axle in this... and emptied the front housing. I know it seems like I got screwed, but there's a huge contingent out there that thinks FJ40s should be restored - now I have carte blanche to ignore that.... so what to do? despite my love/hate relationship with birfields, there are good quality ones out there - so I'm seriously considering just refilling the front with good bits... cheap to do too, so that's not a huge deal.
    Rear axle... if I put the FJ one back in, it's offset and it limits me to the FJ transfer case - there's good and bad to that (all gear, pto availability, generally bulletproof - against - I have to adapt a transmission to it, so that's $600). An Atlas II transfer case is a bit spendy, but once you subtract the street price of a transfer case ($1000), and the $600 for the adapter kit - I can buy a brand-new one for $2200... and it'll last longer than me, they are the best there is - however, none of them are right/right outputs.... so what do I do for a rear? I have a Ford 9" that would work, and parts, lockers, everything would be cheap.... or do I get a full floater like a dana 60 or corp 14 bolt?

    the rest of the suspension goes like this: 3 link front, 4 link rear, coil overs front, coil springs and shocks rear. The motor will be the 400, my brain says put a 4L80e in it, my heart says NV4500... we'll see which wins.

    Thoughts?

    In other news, my Scout 2 steering box arrived, it's gonna work slick!

    As is the good story of my life, friends ask me to weld stuff for them - in this case, a C3 Corvette frame that's getting a full restoration with some modern updates


    so I started digging in my piles of parts
    This rear end I was going to cut down for the "slicks" build portion of my 50 Buick Sedanet. As I'm still waiting for the motor, I'll use it and fabricate a 9" when I get to that point...


    just going to replace the ends with large bearing ends, put a top truss on it and a back truss... should be more than strong enough for what I'm going to do


    400 sbc....
    as with anything, there's a back-story to it. I used to own a 70 Buick Skylark.

    originally powered by this

    then the 400 you see

    , and finally a 455 that I built (over built) headers for

    wayyyy too much header for the motor, but I had big, NA plans for it....
    My brother sold me this car

    and I kept it all the way through college and law school in hopes of building it.... it was so rusty the roof was literally held on by the vinyl top that had caused the roof to disintegrate, so I bought another car and used its parts.
    The day this happened

    this happened.

    he didn't survive. Don't text and drive.

    Anyway, back to FJ40s, my first FJ40 was what got me into 4 wheeling and it got my brother into 4 wheeling as well. Our dad is a former drag racer from the 60s - he used to run at Lions, near LA. So us getting fast cars when we were kids was met with insurmountable obstacles, namely his concerned we'd be just like him (good thing I'm not, eh?)



    So, don't mind me reminiscing - there's a lot of history that will come up as I do this build.

    decision time. I've priced the cost of rebuilding the 400.... $450 for a kit with pistons, $400 in machine work (press on the new pistons, cam bearings, bore for the new pistons, and clean the block). Add another $200 for a cam and I'm at $1050 - there will be no misc. parts because I have scads of SBC parts (like 3 engines worth of arp stuff)... if I put EFI on it, it'd cost at least $1200.

    or buy a LS 6.0 truck motor. That would cost $1750 for the motor, $400 for a pump, and $300 for a program and wire harness.... and it'd be EFI.... the motor has ~150k miles (there are several available)

    What I'd have is the same hp, the 400 would have about 50 lbs more torque

    ​thoughts?

    no thoughts... fine, I'm going to use either a 350 or a 400... I might use the 350 because I'm seriously considering using my AX 15 and transfer case from the colorado pickup
    So I got some more bits tonight
    a truss

    prevailing wisdom is use a dana 60 or 14 bolt - which they are tough rear ends, but I'm not rock bouncing nor am I putting 1000 hp through the axles... so a reinforced 9" should be more than adequate

    of course, for a 3 and 4 link suspension, you do need tough heim joints


    and while I was looking for engine parts, I came across this

    my 1st FJ40 needed wheel cylinders, but I made one work so I ended up with an extra. I sold it in 1991.... yep, it's been traveling with me that long - and I still won't use it because it's going to be 4 wheel disk brakes all around

    decisionmaking again

    The 350 I have is a 93 Chevy truck 350, I thought it was a 4 bolt main... nope, so now I'm questioning again (and don't start with me about 4 bolt vs. 2 bolt) - do I build this as a cheap-build... simply service the Vortec heads, re-ring, rebearing, flat tappet cam; do I buy another motor; or do I hold out for a 6.0 liter? The rear axle and suspension is where I'm going to spend some dollars, and if I get any kind of windfall, it's going to be to purchase a Atlas 2 transfer case. I think that skimping on the motor and trans would be the best place because those are so easy to change when a deal pops up... so a 350/350 combination will become a 6.0l, 4L60e when the right deal comes along...

    thoughts?





    the motor really isn't in that bad of shape and I do have several turbo 350s, include a dual bolt pattern 4x4 transmission

    Yesterday I was gifted these


    ​small yes, but the price was right

    Please don't use a 4l60e if you don't have to! I am planning on doing a swap on mine... 37's and a Supercharger is too much for the poor 4 speed. I think I'd just install what you have and then swap in a 6L when a good one comes around... But what do I know!?

    4L60e is shorter than the 80e, so I kind of have to - however, with that said, I can make the 60e as strong as the 80e... as with anything it just costs a bit of $$

    I guess there is the "Raptor" kit from PATC or what ever they are called.... But isn't there only 4" difference in length? I guess it could make a difference in a rig that size

    The driveshaft is like 19" Given that I'm going up 5"... yes, that's a lot
    in other news.
    the 350 is cleaner


    I still don't know what I'm going to do, but I have a bit of time while I focus on the Posh SAR

    While doing POSH, I'll also be working on this - tonight, fill a hole in the floor
