What about putting a Holley 4BBL on the Torker?

If I even keep the Torker...
Along the lines of a Tim Allen episode, instead of using the Motorcraft 2100 would a 600CFM Holley be an off the wall mod?

Haven't got to the bone yard yet to see if that 304 iron manifold is still on that CJ7...

Thanks,

You don't want the Torker....it's rpm range is all wrong for a Jeep.

 

Ah, Now I understand, *Click* goes the gray matter - starting to remember.
and that Performer got away. *WHIMPERING*
I'll yank it and sell then.

If anyone happens to run across a deal on a manifold. . .

Thanks.

 

That carb would probably work....plan on jetting and power valve changes, + off road needle & seats and extending the vent tubes.

 

I don't know but a 600 cfm seems like a lot of overkill for a 304 and, like the Torker intake, it isn't going to help the bottom end response. I think something like a 470 TA would be close to perfect for that engine if the rest of it is stock.

 

The 470 truck avenger is what I run and its perfect for my 304. I have the old SP2P intake.

 

I agree. Like the Torker intake, it'll work, but it isn't really ideal.

 

I have a ton of experience tuning Holley carbs, but I've had such a hard time with my TA470 that I'm reluctant to recommend it to anybody. However, mine's on a 225 & I live at 6500' elevation, so that makes the tuning much harder....

 

The light blue Jeep that followed me all last weekend (pictured in the Jolly Jeepers run thread in events) runs a TA470 on a 225 and it ran every bit as good as my Dualjet which is pretty darn good off road. However, we are everything from sea level to about 4,000 feet at the highest here so you have much larger challenges to deal with.

 

Mine works GREAT off-road!
However, it has some street drivability issues that I haven't been able to eliminate. I've read about others having problems like this too...it seems to be an endemic problem with the TA carbs. I have a few other ideas I want to try. If I ever get it running like I think it should,I'll do a thread detailing the whole process.

 

OK, I need to ask, what is a TA Carb? I'm drawing a blank.
*GADS* I'm feeling like a fish out of water at times.

you are not alone.

i looked it up.

TA = truck avenger

 

Was googling around and found this antique thread here:
http://www.earlycj5.net/forums/showthread.php?38060-Holley-Truck-Avenger-470

interesting old thread, useful also.

 

Interesting, learned something new today before the second cup of coffee...
Did not know there was a 4BBL smaller than 600CFM.
But at $500 - hehe - wow.

 

If you want to cruise the wrecking yards, you may get lucky and find an OEM Holley application that will work. My favorites were the 450 cfm version used on the AMC 250 V8's. These were full 4150 series carbs with vac secondaries and really easy to set up for small displacement engines. Some of them even had both a power valve and changeable jets in the secondary metering block. With extended bowl vents and the spring loaded needles you have your own version of a TA.

One of the very big downsides to too big a carb is what Tim mentioned in that old tread: the vacuum signal gets weak. And the greater elevation change one works with, the bigger that problem becomes. If you tweak a too big carb to run, say at 5000', and then are trying to trail run at 10 to 11k, it is usually like running with the choke closed-swamped in gas.

 

In all my crawling of boneyards in the past month or so about the only AMC vehicles I have seen (outside of Jeeps®) was
one mustard yellow Gremlin. They sure are becoming scarce.

What type of vehicle was the 250 found in?

_Dan

 

Wow ...that's a scarce application.

There is an aftermarket 390cfm Holley 4150, and you could modify it to work better on the trail with raised vents, float springs, etc. Should be possible to source a used one if you look around. Supposedly the TAs have some other internal changes and the annular booster venturis that make them work well on the trail, but not so great on the street. Don't know the details, but you could find out more by web searching on the terms.

If you want to look for comparatively small 4V carbs, you could look for the ca 350cfm Autolite/Motorcraft 4100 that was used on the mid-60s 260/289 Mustangs and maybe other Ford performance apps. The 4100 is essentially a 2100 with secondaries, and should be an excellent performer on the trail. But you would be competing for these carbs with all the Mustang collectors out there...

Supposedly there is also a small Rochester Quadrajet that was used on marine apps. The Quadrajets are excellent trail performers, but they are complicated to set up.

JMO - at $500 for a new Holley TA, you've basically paid for junkyard EFI, and half-way to a turnkey kit. Hardly seems worth it.

 

I bought my TA470 as a factory reman from Holley.
Don't remember what I paid but it was nowhere near 500.00

 

Ohoh Tim, now you've stirred my curiosity. Would you have any info or links in regards to an EFI conversion for a 304?
I did some searching the other day but only came up with 'new' conversions.
Would the donors be later model FSJs?

Thanks,
_Dan

 

so, I'm following too... mostly the edumakation part.

soooo much good stuff - and just about that moment I think I've got it, wham to the side of the head.... more to know.

Everyone here makes the 'wham' pleasant.

thanks.
