Tunnel ram, linkage and cable question.

Hey Mat, how did you attach the cable to the pedal?

How long is your cable?

Thanks!

Lokar cable attaches no problem to factory pedal, remove the Lokar end piece, ball on end of cable fits in stock pedal.
24", XTC-1000HT is the part #.
Learned this from another member on here.
I think I put a washer on the outside of firewall only.
Just need to get full throttle, got closer by moving cable pull on throttle body closer to center. Based on some research here, I think to get full throttle need to modify pedal or get aftermarket.
 
What type of truck?

(The clowns at auto zone (Need to know that)

Thanks!

Got it bolted down, switched all the soft line for hard line (what a *****!!) , got the throttle cable hooked up (thanks Matt!). Gonna bend the factory pedal just a hair as I cant get the last little bit of throttle (pedal hits the fire wall)
Still gotta hook up the fan switch, temp sensor and fuel feed. Not sure if gonna half *** it for now or just start installing the fuel cell and new hard line from the cell...?

Gotta cut the hood and lots of small BS stuff. But it's getting close. Two weeks away from the shop didn't help any...

I'm very happy with my choice to change the flex line over to hard. Even tho it cost and was a serious pain in the *** it's way cleaner. (In my opinion)

Now I can't wait to fit the drag radials and 4.88s!

Thanks everyone for all the ideas and advice.

Is this thing a stick??
 
Still gotta decide on the TC. (stock converter still) My engine builder says 2,800 but I'm leaning more towards 3,500 as I wanna be pulling as much vacuum as I can before launch and may re cam this winter.

Also how the hell do you tune a plate style carb? I've always had 4150s. do you buy new plates or what? Just tune the primaries?

What about fuel pressure? Now that I'm feeding four bowls vs two, should I up my pressure? I was running 5 1/2-6 PSI. should i bump that up?

You have to find out which plates you have, and then by the correct plate. It's been decades since I did a 4160 so I don't remember the particulars, but in the catalog or one of the Holley books you can find all the plates they offer and figure out what you need.

And yes, a 2800 converter is about stock. I'd call PTC or someone like that and tell them what you have and let them pick it. FWIW I know guys running 5000 and 5500 converters on the street with no issues.

It's hard to get the converter too loose, within reason. A converter that is too tight will screw you hard.
 
I will be calling.

So loose = high stall, tight = low stall?

This twin carb 4160 is all new ground for me. Im used to jet changes. Sucks as I have a ton of jets and zero extra plates...

Yes. 2800 seems pretty low for about anything.
 
Fuel pressure should be good. You now have 4 bowls of fuel instead of just 2. The amount of fuel used should stay about the same regardless of the number of carbs used.
 
Got the hood fitted. I'm gonna make a nice aluminum panel that's bead rolled and dimple died to fix the area around the new carb hat.

I almost wanna run a one inch set of carb spacers just to get the hat up a touch more but I'm gonna leave it at this height for a while and see how I like it.

I got a few carbs with jet extentions on em, they may get looted....

Here's a shot with the front end tilted.

I found out there was literally NO way to attach the carb hat. As the front screen was nut and bolted so I had to tap the holes that way I could reinstall the screen once the hat was mounted.

Also my water neck ain't gonna work.

I think I'm gonna need a 90 degree one?
@j par

What are you running for a water neck?
 
I had that same scoop, hated it.
There are other ways to elevate the scoop.
Or you could drop the hood down in front of the scoop.

Did it not perform or just hated the look of it?
I'm not running air cleaners so fitting them in and all the pain of that is not an issue.
I kinda dig the old school boat vibe it has.

Your not going to be happy at all with 2800 stall! It’s part of the reason tunnel rams got a bad reputation on the street. People run them because they look cool but don’t build a combo that runs. You need rear gear and stall to make the most of it. I’d run 4500 stall. Now before people start pissing and moaning about loose converter on the street..... I have an 8” 5500 stall in my dart and drive it everywhere! It acts normal till you flash it. It’s about efficiency! Cheap ones don’t have it. This is not the place to cut corners. Take it or leave it but I’m certain people that have done this the right way will agree.
