    Old and New: 5.7 Vortec to 6.0 LS Swap, ‘69 FJ40

    Really interesting. I’ve never seen that setup before using a Nissan slave. Looks to be mounted on the passenger side of the bellhousing? I will have to see if the SM420 bellhousing has those mounting holes, they are different from the SM465

    Thx, this is good info. I’ve got the later version master cylinder, truck must have been a late ‘69 as it’s the common triangular 3 bolt mounting pattern. I’m suspicious that the pressure plate fingers are likely different from the CenterForce somehow. As in they need more overall travel to...

    Old and New: 5.7 Vortec to 6.0 LS Swap, ‘69 FJ40

    So….. even with the adjustable pivot ball and the fancy adjustable McLeod throwout bearing, I’m nowhere near the .050” McLeod is calling for. I’m probably more like .010”-.015” if I was to give the throwout bearing any free play. It nearly impossible to get the transmission into 1st without...

    For now, stock FJ40 clutch master and slave. I’ve already replaced both with Japanese made units. Old ones were working fine but I wanted to eliminate that as a potential issue I have a stock SM420 bellhousing and stock fork. I essentially cannot get enough “travel” out of the slave to...

    Here’s the steam line. Found an OEM 4 way piece from a 5.3 in a junkyard, both the front and rear of the heads are tied together Used a 4AN compression fitting on the GM tube and ran it over to the water pump outlet. Threaded the water pump 1/8” NPT and called it good. Seems to work, doesn’t leak

    Steam vent, that got tied into the water pump actually since my older BeCool radiator didn’t have the appropriate fitting and I didn’t want to weld one in, I’m REALLY fighting with trying to get the clutch to release properly currently

    Still slow as all get out with the SM420, it simply can’t shift fast enough 😂

    Project Wisdom Turns Folly to start in Ernest.

    I haven’t heard of that drivetrain in a 40, not that it hasn’t happened. IMO, there are more reliable and easier to work on engines that can be built to make lots of HP for pretty cheap. Just because the initial cost is low doesn’t mean it won’t cost a lot later on. These projects tend to spiral

    The LS seems a bit quieter compared to the 5.7, not much tho. At least it’s not making a bunch of lifter noise 😂 The power output is respectable. 2nd/3rd gear fairly hard on the throttle and it REALLY takes off. Wraps the link suspension up significantly. 4th gear feels milder, I’m putting...

    This is more or less done, almost Limited the stroke of the PSC ram to 7” using some pieces of UHMW It drives 👍 I like how clean everything turned out. Things that worked: All the AN fittings. Zero leaks at initial startup, gotta appreciate that The repurposed FJ40 turn signal...

    Ugh, the price you pay for hardcore wheeling. Took the PSC ram apart today in order to internally limit the stroke. Pretty obvious that the shaft is bent 🙄, 2nd one in a year Cooler arrived tho and I got that installed and plumbed. It’s close. Once the ram is back together I’ll try...

    Thx, getting very close now. Waiting on a new steering cooler which should arrive Monday

    Saginaw box is back from PSC 👍 Fabbed up the steering shaft support today. Used a stainless Borgeson bearing and tied it into the AA motor mount DUN The shaft fits just BARELY between the frame, exhaust header and shock hoop

    Yes. That is not useful, at all. All it gives you is the option of routing rubber heater hoses through your firewall, which I don’t like. They are not correct for AN pushloc hose and because the core is set up the way it is, you are stuck with the barb fittings 👎 It’s odd because Vintage Air...

    Heater plumbing is done. This might not look like much but it was a pain to get things to fit, go figure And got REALLY lucky with the exhaust. I built the stainless crossover long before the engine was ever test fit, just had an idea of where I wanted it to terminate basically Original...

    NOLA- A Build Story...that goes Diesel

    Yes, definitely saw an increase in MPG and I also did OD transfer case gears and 3:1 low range while I was in there. Hard to say but I’d guess most of the MPG increase came from the OD gears

    Here’s my main gripe with Vintage Air heaters and AC units. Granted I only have heat in my 40 but the AC units are the same Vintage Air uses #10 male AC fittings on their heater core. INCONVENIENT to say the least. As far as I could find, there is no such thing as a #10 AC to 10AN fitting...

    Nice. I’ve had zero issues with my part time kit

    Yeah, ultra clean. And unfortunately a huge price tag to go along with that

    Upper radiator hose is done. Dollar bill is for size comparison, they are LARGE full flow fittings.
