The Barn Burner

I'm betting that a 70 wheel cylinder is big. if you only have a 3/4 bore on the master and say a 3/4/ or 7/8 maybe even 1" or 1 1/8" on the rear or maybe even bigger will that make a difference? I know some people put a gm 1 ton cylinder on the back. I'm guessing you will need a bigger master to make that work. I have know idea what a gm master cyl bore is... maybe a good place to start and compare from.

also double check to make sure your shoes are not too far from the drum and you're not using up all your stroke on the MC before you even make contact w/ the drums

Right now the pedal travels almost to the floor before locking the brakes up. The firewall is flexing when the pedal is depressed so I'm building a new plate mount for the master cylinders and pedal bracket to keep it from flexing. The steering shaft comes really close to the balance bar and prevented proper rod/plunger adjustment. I will move the whole assembly over a half inch to keep it from binding which should allow me to get it dialed in.

While bleeding the brakes I noticed the left rear was the only one with air coming out of the bleeder valve. I checked the lines for possible leaks coming from the flares but they were ok. When I rebuilt the d70 I replaced the left rear brake cylinder with a different unit close to the o.e. specs. It all worked but I'm assuming that it's the culprit, in hindsight I shouldn't have swapped it out. Really doesn't matter now since I'm doing the disk brake conversion.

I have seen the same wilwood system in rigs on pirate and in Crawl. I noticed that the pedal sweep in the pics are longer than what mine is set at. I can only speculate until I make the changes and see what the outcome is. There's always room for adjustments and it will just take some fine tuning.

Before the trip I had to pull the shafts and drums off to unstick the drum wheels. After I got it all back together I jacked up the rear axle, used a brake spoon to turn the drum wheels and spun each tire until the drums started to drag.

Trans out



Hubs installed

So what is the new trans going to be? Same th350? Anything special in it, what torque converter are you going with.

What are you going to do about cooling?

[Sharpe]

I think the trans was just mad at you for getting so much overspray on it.

I'm sticking with a th350 because I already have the stak adapter, shifter, deep trans pan, built a crossmember, etc for one. Haven't decided on the converter and build for the new trans, I'll be talking it over with Ricky who will be doing the work for a final decision. I imagine it will have a similar build to the th400 in the Chevelle.

It already has a TCI cooler mounted in front of the radiator, you can see the cooler lines in the first trans pic.

That's just blue accent on the silver housing...

Didn't you have a fan related issue?

My bad, I thought you were asking about cooling for the transmission.

Two of the blades broke on my old universal fit flexalite, worked great on a 258 but didn't move enough air for the 383. I now have a flexalite S fan with a large shroud, no more cooling issues.

did you ever re-mount and rewire it? personally, i see no need to.

[TMatheaus]

have you made any more progress on this lately, will it make it to karls bach party trip to 47

Messed with it a little while I was in town last weekend. I'm planning on doing some work on it this weekend though. Need to check on the status of the trans and maybe something else.

[CheapJeep]

Did a little work this past weekend. Made progress on the new rear anti-wrap axle truss and disk brake conversion, I'll finish it up next time. I have a few other small items to wrap up but nothing major.

The parts for the transmission came in and it will be ready to go late next week after they get back from racing in Gainsville.

Brought my tools and stuff back to CS and finally made a little shop area in my apt. Working on installing the rear pinion brake for the stak. My neighbor saw me bringing the stak in and thought it was pretty funny, didn't know I was in to this kind of stuff.

Forgot to bring my camera last weekend but I snapped a pic of my apt workspace.
