Post subject:  List 6464 1050

I posted an intro in the Newbie's Corner so I will not cover that info again here. On to the good stuff.

Ran across an interesting 1050 the other day. It is a List 6464 12R-4325B that was worked on by Chuck Nuytten back in 1996. It is in very very nice condition and I'm not sure it's had fuel in it since it he had it. Gaskets were the old brown ones and were not stuck. Jets are 88's and there are no PV's in it. The CN stickers on the float bowls are the old 214 area code stickers and look brand new. I sent him an email with his serial number to see if he had any records on it. He performed his "4003" labor package on it which consists of blueprinting, venturi shaping and polishing, booster work and internal circuitry modifications.... for whatever that's worth. The linkage has been changed to the soft progressive which I may end up changing to the standard progressive later.

Current carb is a Holley 950HP with QuickFuel 34-105 blocks and a Proform baseplate. I plan to use those blocks on the 1050 to convert it to a 2 circuit.

The engine all this mess has to work with is:
545" BBF 11.5:1 91 octane pump gas drinker
32 deg timing locked
FRPP single plane intake
Herbert solid roller cam
Dur @ .050 Int-Exh: 260/270
Lift 1.7 -1.7 Int/Exh: 685/685
Lobe Center: 108
Trick Flow 429/460 cylinder heads
4000 converter
honkin' C6
3.55 gears
28 10.5 MT slicks.

Normally, I run in Amarillo where our track elevation is 3600' MSL and our D/A is usually 6000'+. Not great air, but it's what we have. This car has not been in the 10's in Amarillo, but has run 10.50's in good air. My ultimate goal for this car is to run mid-10's in Amarillo and low 10's in good air.

Anyway I wanted to throw all that out there up front as a point of reference.

Now back to lurking and reading!

You also may want to swap those boosters also..

That's a good find, you don't see 6464's too often anymore.

Just picked up 6-32, 8-32, 10-32 taps and a handle at Ace Hardware a couple of doors down from my office.

They have individual drill bits down to 60, but nothing smaller. I will probably just get the HFT drill set instead.

This is gonna be fun.

James I got my small drills sets from a vendor on fleabay for cheap. In fact, I bought 4 sets cuz I knew I'd break a few along the way and I was right.

Nomad is making up a list of stuff to get and where to get it if you want to wait a day or two to when that list is posted.

A little progress last night.

Mocked up with the Quick Fuel blocks and the newer bowls off my 950hp. The 950 bowls look nicer and have the larger needle and seat setup. I also swapped on the 50cc accelerator pumps.

Tapping the transfer slot circuit 8-32 for a brass set screw restriction.

Tapping the air bleeds 10-32 to use standard Holley bleeds.

Finished.

Looking good James. If you can successfully drill and tap that zink based "monkey metal" then you've overcome one of the major hurdles. ;-) That stuff is NOT user friendly!

It wasn't bad. I'm pretty handy with a tap and I'm not afraid to drill things though. lol

Having both carbs sitting there all together, I was amazed by:

A. how FRIGGIN' HUGE a Dominator really is. (my n00by-ness showing through)

B. how light a Dominator is. That 4150 is one heavy turd!

Also to note, I was looking at the Quick Fuel 6-32 bleeds and noticed they apparently drill them twice. They seem to all have the same diameter initial hole (large) from the top, then the actual metering orifice is finish drilled later (small). I suppose that makes them easier and quicker to manufacture.

Both of these are methanol carburetors. I have two 750s for the tunnel ram and the Dominator is an 1150 that started life as a Bill Mitchell carb. Note that the PCI bowls make that Dominator even larger.

James your going to find out that your not going to need that 50cc squirt when you get it right..That chapter will be when your on the track...

Also, since you now drilled and tapped for the air correctors you don't need to buy anymore. You can just drill out 10-32 set screws.

6,8,10/32 brass set screw are alot less $$$ than the Holley bleeds.
You can get a box of 25 of them for less than 4 bucks or so..

For the air bleeds, I really prefer one with a positive stop. I might have to look around for bleed blanks or socket head capscrews or something. Still looking into that.

Angle channels were opened up to 0.159 tonight and the idle jet holes were drilled and tapped 6-32.

Now I just need to order a few things from McMaster-Carr. :)

positive stop? You just need to tap them deep enough to bottom out the set screw in the hole. I tap shallow then finish with a bottom tap. That gives you a positive stop. I have my taps marked so I don't tap to deep.
