Outer Limits 4x4 Board

I am fitting a 454 big block in to my 04 patrol ute does anyone know what
kind of carbie will be good and not flood when going up big hills

are you allowed a carby on an 04 vehicle?

speak with GQ351.. he has a 454 in his now.

who would want a carby in an 04 model vehicle

Injection is the only way to go, carby wont pass emmssions for rego/engineering on an 04 patrol.

LSX injextion from GM is a streight bolt up job..

Ever think maybe its not going to be registered?

Who would want a carby in anything except the garage rubbish bin?

even then injection will be better than carby for offroading

i hate hollys with a passion, but their truck avenger carbie would do your job

what is a carbie?

Go injection for sure.
A carb worth having is $600+ jetting etc
inj is about 1k.

I am running inj on my off road race car as I see it as less trouble than a carb. And there are no hills. Its not just the carb but dizzy, leads, timing, points, fuel consumption, cold starting, etc

That said a had a holley on the boat with hei and it ran well.

If carby was the only option and clearly it is not....stay well clear of holley, you may as well fit up a 44 gallon drum and feed it directly to the manifold, any thing with complex idle and metering circuits will serve well and not suffer from the tuning issues you will be almost guaranteed of getting from a holley.

Something like a Edlebrock carby with vac secondaries would suit well in most applications.

if you were looking at hard core stuff....injection, even TBI would be far better and the only option in my opinion.

Predators if you have to go carbies. Had twin predators on my 454 ski-boat I had many years ago. Completely sealed unit & once tuned they get closed up & trouble free. Mind you the cost for 2 of them is equal to getting injection so ............



brooksy

a modded holley to suit=1000

injection to suit that application=3000

and its been proven time and time again bang for buck a carb will
provide more power and ease of tuning!

but injection as said is prolly better for wheeling in this case!$$$$$$$

haha good luck with proving that one

alot of ecus have an auto tune function using a wideband and base map. good luck finding a carby that has that

My carb has auto tune...

It goes out of tune all by itself.

x3,

have you missed the LS revolution. You can buy an entire ls injection package s/h for the price of a carb.
have you not noticed nearly all dirtbikes are now injected
injection was invented / perfected in the second world war to allow planes to bank, pull negative g's etc, there was reason for it 50 years ago - because carbs were inadequate.

would like to see this you speak of throttle body,ecu,wires,fuel pump plus all the b/s and a tune!for the price of a carb!

rec boats are a pretty simple application: very limited change of atmospheric pressure, not much in the way of static angles, fairly constant running rpms...

not to fit a 454,
but for example an entire running crate ls will cost about 3/4 the $ of a carb 454 and make more power.

eg from

http://www.suburbanimports.com.au/motors.htm

CHEV 6.0LT GEN 3 - New fuel injected motor.
The new Heavy Duty 6.0LT has a cast iron block with a 6 bolt main cap. The Bore is 101.60mm(4inch) and the stroke is 92mm (3.62inch). The Aluminium Heads and roller Camshaft are the same as the 300kw (400hp) corvette motor. 6.0LT GEN 3 Gross Power is 400HP @ 5600 and Gross Torque is 420LBS @ 4200RPM. The cast block is a lot stronger than the LS1 5.7LT alloy block and is stronger for bigger horsepower. #502. ( Will take place of LS1 5.7LT Alloy motor.) 12 months guarantee. 100% new. $6700

CHEV 454CI- New Motor. 100% new
Chevrolet 454CI Motor. Comes with water pump, harmonic balancer, 4 Bolt mains, cast crank, hypertectic pistons, HD rods, air cleaner, performer alloy performance intake, rotchester carberettor, HEI electronic distributor, dipstick, leads and spark plugs, gear reduction starter, drive plate. Cost $8500 #207B. 12 months guarantee.




I have receipts for mine for crate 6.0l, starter, alt, rear sump, pulleys, loom, just need $100 pedal and $400 ecu to run. entire cost $5500

as for s/h ls motors - you can buy a worn out one complete for 1k, incl loom and t/b etc add $250 for an ecu and $300 for a tune - thats carb dollars. Granted its not 454 specific, but neither was the tuning carb vs inj comment.

I have had several cars with carbs - they need chokes, run poorly when cold, spill over the back and stall on hills etc. Also they use shit loads more fuel in performance applications.

It goes out of tune all by itself.

hey that must be a special holly feature cos my 350 on the xe does that on its own, i think its auto detune made to keep mechanics in business

how would a carbie flood going up big hills? if anything the mechanical fuel pump would starve to carby of fuel, but luckily most carbies have a big enough bowl to hold enough fuel at a time to prevent starvation, and you wont need a surge tank..


correct me if wrong

The angle of the hill makes the fuel spill out of the bowl flooding the motor happens to me all the time. I'm going sidedraught carbies to prevent that problem but good luck with doing that on a v8 Ls1 is probably going to be the cheapest/best option even if you already have the 454.

To get the holley range of carbs not to flood on steep angles you can get various aftermarket accesories, vent tubes that connect over the top, jet extensions, anti sloshing plates etc etc

An engine that big belongs on LPG.
That'll get the results you are after and some money back from Uncle Kevin.

putting an inj 454 in my gu with auto. have the conversion for a patrol man if you need it. its still hanging off the back of the motor in the garage.

454 TBI set up with manifold. http://www.suburbanimports.com.au/otherparts.htm ..$650 only needs remaining sensors and ecu which a delco can be picked up for $50-100 ecu rewrite $50 well below the $1000 carbie with without mods to make it more reliable in the scrub.

i knew a few guys a while back (about 12 years ago) that used Holley injection... had nothing but dramas with it. Ran great at full throttle... was useless down low. They may be a bit better these days.

actually, slightly off topic.... i rode in a HQ years back with a blown 454 in it...... giving me a chubby thinking about it now........


where did i leave those tissues............
