Four speed install

[gsharp]

I own a 64 C10 that I just put a 454 BB with a 4-speed Saginaw transmission. Looking for some info on how to hook up the clutch linkage and accelerator cable? I'm also putting in a four core aluminum radiator looking for supports for it. Thank you.

A mechanical clutch linkage with a big block is going to be very difficult. I would just convert to a hydraulic clutch. Much easier. I do make those conversions if you are interested.

Have you converted your truck to a cable throttle already?

Radiator saddles and upper support for a 4 core radiator are extremely hard to find. Is your aluminum radiator a replica of the original downflow radiator? If so you might just have to make some saddles and a top support for it.

[gsharp]

What does the hydraulic conversion consist of? I already mounted a vacuum brake booster and converted front end. I do need cable set up for the accelerator. One other thing I can't find is 1" thick 6-lug rotors all of them are 1-1/4".

When I put a 396 Big Block in my '62 Impala, I believe I used all the original Small Block clutch linkage. I'm wondering what would make a truck be different from Small Block to Big Block?

In regards to clutch linkage, not a dang thing.

clearance at the back of the eng (BB)with the firewall) unless you modify the firewall on the truck. passenger cars had more room there.

That was not the OP's question. He has the engine in apparently.

I am well aware of the firewall issue.

We are doing that as well.

I just wanted to see if there was a kit or something.

Look here. You might need to make your own kit from these parts.

Thanks man!

[padresag]

if you can mount it in the stock position which means that you will have to modify the firewall for clearance you should be able to use the stock clutch linkage. There is no kit , just the stock pieces shown in the link above. if you position the eng forward then it would be the simplest way is to go the way that the Capt recommends with the hydraulic system

Just for curiosity, what actually needs to be done to the Firewall when dropping a Big Block into a '60-'66?

As much as I was against it, unless it was just a junker, when dropping a BB into a '55-'57 Chevy car, a hammer to the passenger side firewall would accomplish it. When using stock mounts anyway.

There is no stock position for a bbc in 1964 trucks they all had sbc or inline 6 motors. I have a 1965 that I am building in my shop with a 502 bbc in it with the tall valve covers. I did not have to put one dent in the fire wall it fits nice. I would do what captainfab says put a clutch slave cylinder on it and a clutch hydraulic throwout bearing on your truck. I used speedway motors 910-25610 clutch hydraulic throw out bearing works good.

[padresag]

the stock position for either 230-250 0r 283 engine which is the rear holes in the frame .
here is a link to a big block install and on page4 and 6 it shows what he did for relief for the valve covers. Jon did also use the later motor mounts. there were also bb perches for the 69-72 trucks. the Capt is more familiar with what perches to use.
Jon did use an AT in this install

Nope,

Stock motor mount position (Big Blocks and Small Blocks share these) and the valve covers will make contact.

I chose to stay in the stock location so modifying the firewall is required.

You can go to my build thread and see I am kind of insane with how meticulous I am when it comes to layout and build accuracy.

I should seek help.

[shortstep60]

My bbc didn't hit the firewall and I will leave it at that

[gsharp]

I have the short valve covers and they clear the firewall barely. Used the front mounting holes on crossmember.

Without going outside to look, lol, does the Small Block use the Front Holes or Rear?

[gsharp]

I know the straight six uses back holes and I think the small block does too.

[Captainfab]

The rear set of holes.

One of the biggest issues with installing a big block in a '63-'66 with a manual trans is header/manifold interference with mounting a ballstud on the block. Plus the big block will not have a ballstud boss in the correct location. Thus a bracket will need to be fabbed to position the ballstud in the correct location to line up with the bracket on the frame.

But it sounds like there are others that know much more about it than I do, so I will bow out now.
