Rock40

Time for another update, boy do I have a lot of them to catch up on....the little time I get these days I am is usually spent doing something small to the truck or working on our house and I don't have much time to get things documented. I also...

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

So I’ve got no idea if this will help or not. I have a similar setup in that I have a GM v8 (5.7 vortec) with an SM465, stock iron bellhousing, what looks like the same basic clutch fork, and a 12” clutch. I run a later model FJ40 master with a...

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...

What year MC ? I have same set up and I have a bit of push left after the disc releases so I know I have enough travel. I have had to double pump it to get it to quite dragging after it sits for months, no leaks or drips. I am curious which...

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...

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...

what have you got for set up ? I am using a late 1970 MC & a stock slave, gm bell house & fork, luk clutch, at rest its about a credit card off fingers, I have found the MC don't like cold, at least my museum piece that still works doesnt, it...

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...

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

Where did you tie steam vent in ?

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

Nice. What's the new 1/4 mile time? 😁

I sandblasted and powder coated the widow frames . And the pieces that go above them on the hard top . I have All new Rubber and Felts . I am going to have the hardtop sides sand blasted and just Powder Coat the inside and I will paint the...

I’m dropping off my styrofoam mock up tank at the fabrication shop tomorrow! I went with a bolt on style in tank fuel pump stand with a Walbro 255 LPH pump and a standalone cylinder floatless style sending unit from Tanks, Inc. The stand has a...

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...

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...

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...

Couple more. Just need to put some exhaust hangers in. I'm tempted not to run it all the way out the back and just let it dump right there. Last one is where I ran my fuel pump and filter.

This weekend I pulled a rear tire off to see what spacer was on there and decide on which spacers to buy. I couldn't help myself from making a sneak peek... (Yes, I know I put a tire mounted up for the passenger side on the driver side... I...

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...

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

Looks great!

Now to make it real 😳🫣🤔🙏😃
