72 620 truck KA Build - Tank.

[RustedRails]

Those gauges are killer. Nice choice on the needles too. Usually see them in white. 

[Tank.]

Worked a little on the master cylinder/booster setup. I’m changing to a 3-3/8” square booster bolt pattern (which is a very common booster pattern) and a 7” single diaphragm booster. And I got a really good deal on a wilwood master cylinder that I couldn’t pass up from a buddy. 

 

So I made an adapter plate out of some 2” flat stock, cut 4 pieces and welded them together.

 

 

 

Now the idea is to weld the OEM booster bracket to the bracket I made. I’m not going to weld it until I put the steering column in so that I can get the booster exactly where it needs to be.

 

 

 

 

 

So now I’m pretty much running a very common chevy pattern of which parts can be found anywhere for years to come.

Nice work. Making me feel like a slacker.

It took me 12 years to build my Z, I’m really trying to have the truck done a little faster…lol I’d like my son to learn how to drive a stick in it, he’s 5 now.

Finished up the mechanics of the brakes, and made the accelerator cable. 

 

 

 

Just ordered a new rubber stopper for the brake light switch, but otherwise the brake setup is all good. 

 

For the accelerator cable, I took pieces from the original and modified the frontier cable to make one. So at the firewall to the pedal, it’s 620 parts. From the firewall out, it’s frontier. Turned out to be 27” tip to tip.

 

 

 

 

I cut the frontier cable, and the made a new end for it. So I drilled down in a piece of wood about 3/8”, then melted lead in it with the cable. From there I shaped it to mimic the original so the oem clip still works for the 620 accelerator pedal.

 

 

 

 

 

Works great! From there I made a pedal stop on the back of the oem pedal. Forgot to get a photo of that but I will at some point.

Great info. I'm following along behind you with a ka24 myself. At least I'm heading in that direction. Maybe.....

 

 

I have the motor anyway.

Nice, looks like a clean example to start with.

Well this escalated quickly!  LOVE the front end set-up.  Super clean work.

Inspiration to get my project back on track...

Thanks, I’ve done a few other things recently and need to catch up here but hope to work on it more since it’s pretty much winter again.

Worked on the air cleaner a while back. I adapted an L20 intake/air cleaner to the truck intake. I still have a lot of cleanup to do on it and paint it but functionally its good to go. Why did I do this? I looks better than the plastic crap from the Frontier.

 

I cut the center of the base nearly all the way around so I could level it to the engine, then welded it back. From there cut the cross piece that the top screws to and rotated it to work with the KA intake. Then I sectioned the air cleaner studs 1-7/8” so the L20 intake could bolt to it, drilled 2 holes and it now bolts down. Finished it by drilling a hole in the inner fender for the intake tube to go through.

 

 

 

 

 

 

 

I plan on adding some sheetmetal in the inner fender to keep dirt/water/debris from flying up in there. A kind of scoop of sorts that goes down.

[Tank.]

As for the battery, I am relocating it below the bed. I got this plastic box and made a cage for it. The upper part will be welded to the bottom of the bed, the lower part bolts on so the battery box can be lowered out. I plan on using the old fuel filler area to mount jumper/charging studs.

I put the bed back on to test fit and fabricate a few things. Dialed in the rear ride height as well.  Seeing it like this helps keep me motivated.

 

 

 

 

 

 

And for the new fuel filler, it’s in the bed. I already made a hinge for it, just need to weld it on. The fuel filler in the bed is a love it or hate it thing from what I’ve read. I still plan on using this for truck stuff but this was the best way to do it to keep the tank as high as possible.

sooo good. Love it

Tank....trying to contact you via msging on here.

Looks great Tank, you've put some slick touches into the build. Curious as to your gas fill location in the bed floor. Won't it be a PITA to fill and guess you won't actually be carrying anything?

I do plan on using for light truck stuff so I’m still working out the details for the filler. It’s been a while since I have done anything to it but hopefully I’ll be able to put more time in soon.

[EDM620]

Making some assumptions here, tank is behind the axle so the fill isn't too far forward. I'm visioning a tunnel above bed floor with the actual filler acessed maybe via a door in the tailgate? Kinda like 70's GMs with the filler behind the license plate. Protect the fill line (and vent) from impact damage...

That air cleaner is dope. Nice work. B)

[Tank.]

It’s been awhile! Starting digging in again on this thing and had the body sandblasted. I primed the bottom and sprayed 2 coats of raptor liner, I’ll use this in the bed as well. Then started cleaning/smoothing out the engine bay.

Oh how I wish my cab floor had been that solid!

It surprised me when I first saw the truck. The only patch there isn't because of rust, it was simply to give a bit more room for the exhaust. Didn't have to do it, but it will be better with a little more clearance/breathability.

That air cleaner is sick !

[mklotz70]

I like the air cleaner too!! :)  I did a how-to for doing it with a weber.

Hey @Tank., how's it going?
