Not really tech, but proof of the Holley TA

[GMCTruxrule]

Just in case if anybody wonders how well Holley TA carbs work, this pic should be the proof.

Sitting at this angle, my motor was running, never missed a beat.

And no, no trick photography.

I know that people look for carbs that work at extreme angles.

My recommendations.

[Odin K30]

Well that looks steeper than the 40 degree climbs Holley claims the TA can handle.

What is that a fort?

[spidr]

Volcano??


How's it handle on it's side?

[44boggers]

i have a 660 TA and had to jet down about 4 sizes and think it is still too rich, how is yours? Did you have to mess with the jets?

[onetonbb74]

Yeah, the t/a is a great carb for 4x4.

[GMCTruxrule]

I have had it at on about the same angle on its side. Never stalled out.

And no, no volcano or fort. Its the left overs of an old bridge.

Edit: 44Boggers, never messed with the jets. I haven't had any issues with this carb. Now the first one i had, thats another story.

What do your plugs look like? I didnt realize it needed to be jetted down untili pulled some plugs, well actually one time my plugs were fouled, then i knew they needed smaller jets.

[GMCTruxrule]

My plugs are always clean, well, maybe just a little on the rich side. I suppose that I could down jet a bit, but I just never messed with it.

[44boggers]

ok hmm, maybe mine was jetted wrong from the getgo

[FL*CRACKER]

Good to know. I've been meaning to do a search on performance of the TA. This about settles it. Does anyone who has run this carb have any cons?

[Boogerking]

I had to adjust my floats a little lower than spec ... The carb ran 90% right out of the box .. minor tweeking to get it on the money ..

[GMCTruxrule]

Yes, there are a few cons.

Some of the original TA carbs were not worthy performers.

I posted up here a few months back about another TA carb problem that my friend ran into. The coating inside the fuel bowls on some comes off and jams the floats, leaving them stuck open.

its not a fool proof carb, but they are definitely making improvements, and honestly can't say I have had any trouble with mine.

[Loose07]

I must have got a crappy one very un predictable mine would have never even made it close to that angle before cuttin out sitting on the bench now been debating about throwin it against the wall gonna get a demon instead

[Cheepin]

For the price of that carb you can do a swapyard FI.And run at all angles.Just my .02$

do NOT buy a demon. That, in my eyes, is wasted money. Get a quadrajet, and run it. one floatbowl, no massive fuel leaks. its either that or efi.

you couldnt give me a truck avenger and i run an 800 holley double pumper with offroad needles and seats... and it still doesnt like hills unless im hard on the throttle... and since thats the way i drive, its not that big a deal.

That pretty much says it all.

How does it do when you give it some gas and get the truck bouncing?

[philadelphia]

Demons are for drag race guys who dont know any better to run an avanti or the like.

I run a 750 double pumper with vac secs.It came off of my sb2 headed 440 stroker in my rx7. I have off road needles and seats..Its jetted as small as it can be. I run a stock mech dodge fuel pump and it still sucks..It does run at angles but start hopping and bounching around and it starts to stumble..

I have to rev the piss out of the motor to clear it out often after rock gardens and the like. and forget about trying to cralw up a waterfall.

The only difference from the ta andf mine is that i dont have wistlers..They may make a difference i dont know.. But i sure do miss my 800 cfm Q jet.

I will be running TBI soon so no more worries.

fixed

How much are you guys paying for those carbs? A quick eBay scan shows $350 or so could get one to your door. A buddy and I swapped an entire TBI 350 with an SM465 (32 spline at that) and NP205 (with VSS) into his truck and he only paid $400 for the whole package which is why I ask. I understand the fact that a carb is easier to adjust for modifications, but I'm having a hard time wrapping my head around the benefits short of that unless it really does work out of the box. Then again, the only carb I've ever had really good luck with was a Weber DGV and that isn't going to feed much of a motor.

For that kind of money TBI or better yet TPI can be had on your SBC.
Carbs are ancient "tech" which are outperformed by throttle body and tuned port EFI.

lol, yeah, ok.

sure, for going slow with lower hp expectations. If you want to settle for mediocre performance, then EFI is the way to go.

Haha


Oh wait youre right, thats why vehicles produced today have more HP torque and better driveability than they did 25 years ago because they use carbs........oh wait

I think the part that you missed was where TBI or TPI is equal to or better than a carb.

it isnt.

Today, nobody uses tbi from the factory. tbi is old news. if a carb lasted from 1904 to 1986, then why is TBI so much better if it lasted from 86 to 95?

Go to the drag strip and count carbs and throttle bodies and come back and talk to us

[woodchuck2]

I ran the Holley T/A on my ole Ford with no issues when it was new but now after running it for 3 yrs and sitting alot the pile wont even start the truck anymore. Every Fall when the truck got parked i sprayed the whole carb with WD-40 to keep off corrosion but apparently the internals got all festered up. I use to periodically start the truck when it was warm out and let it run for 20-30 minutes but now it just sits. The last time i wheeled it was this past spring and it ran like ass. I havent even bothered to check to see what is wrong with it as i am now building a different rig that has TBI.

Carbs have their place such as drag racing or mud racing. But for better fuel economy in cold weather and better performance in the off-road then TBI, EFI are the wiser choice. Reliability i would say still goes to the carb, i have put a gas can on my roof before to get home when a fuel pump crapped out. Try that with EFI.
