Outer Limits 4x4 Board

Holley's new Truck Avenger is the first 4-barrel designed from the "flange-up" as an off-road carburetor. No other carburetor comes close to the Truck Avenger's performance at extreme angles over rough terrain, and it's awsome stump-pulling, trailer-towing, mud-bogging low speed torque and throttle response. So check out these features. Then install a "No Trouble" Holley Truck Avenger for the time of your life, whether it's off-road, or on highways and city streets.

• Exclusive new metering block eliminates fuel spillover through the boosters at extreme angles. Flood-free operation up to 40 degrees while climbing, and 30 degrees during side hill maneuvers and "nose down" descents. This means off-roading in confidence without the annoying hesitations, stalling and flooding often associated with carburetors in an off-road environment.

etc etc.

Would you think this is enough? I am thinking that beyond these angles I will probably be on my way to my roof anyway

Would you agree? Does this sound like a reasonable non injected solution? I can get this for USD$331.57 plus P&H Holley projection starts at about USD$1400 I think.

Haven't done a whole lot of research but it looks like it will cost me about that for a re-co rochester

Would this be a suitable purchase?

Opinions

get LPG. should be able to pick up a second hand setup for not much more, then you have no angle issues ever, and as a bonus you can halve your fuel bill.

talk to Dan, shorty40 on here, his truck runs Holley injection.

agree good s/h gas better option....

another thing is if ur not keen on gas is to inject it.......i know most ppl think very expensive but if u have some mech knowledge can be quite cost effective long run better running engine/fuel econ/any angle.

shorty 40 got a 2nd hand projection setup from ebay in au cheap

Or I know of a recently reconditioned Rochester which hasn't been used...

how cheap woul it be NJ?

guy here at work has one of these in his bronco (770)..

so far he sez that its ok on angles when its running, its only when it stalls on an angle that he sometimes has issues starting up again.

apart from that I dont think he has had any other issues with it.

You have PM.

I ran a standard Rochester Q- Jet for years on a FJ40 with a 350 Chev.
At the time it was the only way to go for a petrol V/8 that actualy went bush.I never had any problems that set up.Holly have just marketed their new Carby to do exactly what the Q-jet did anyway!
Cheap to Buy!
Cheap to Change-Over!

except that time the float stuck...

Hey guys

The EFI setup was a pain in the arse to be honest. I was very lucky to find a Holley EFI TB on ebay cheap. But the rooting around to find an ECU, fuel, pump, adaptor plate etc was a hassle. In the end Sam @ OverKill sorted it all for me. If it wasn't for Sam, the cost and hassle would not have been worth EFI'ing the 40.

If you can get all the bits cheap it is awesome. Buying from the States is expensive

Have a look at my members thread. I think I put a breakdown of what I had to get and rough prices

As an idea for you though, I had a rochester QJet before the EFI and as good as the carby was, it is nothing on EFI !! Same can be said for LPG, although this has a fuel cost saving advantage. But I didnt want the hassle of big tanks etc (not to mention hardened valves etc)

Hope that helps

I have seen too many fourbys with holley have too many starve/flood issues. I have a couple of mates with Rangies fitted with holleys and they always have problems up/down hills

One thing Land Rover got right was the twin stromberg 175CD carburettor. Performance wise on-road is restrictive but this pays off when off-road and they don't have the flood/starve issues that most carbies have.

But you still can't beat EFI Just my thoughts on the matter.

I have been fortunate enough to have had experience with both projection 2 barrel 670cfm and now a 750 vac seconndary carb.
The Projection was very good offroad and on road it could have been better with a few tricks fitted like surge tank and auto choke hooked up but the only downside is when a few mods to the 351 it was fitted to it started to run out of revs. It would be ideal for std-mild engines.
The holley is fitted with OFFROAD needle and seats vent extensions and dual metering blocks and secondary spring lightened has no trouble with angles up down or on its side. These parts are available from most performance shops and should be in the new offroad holleyThe power increase is significant over the projection. Only problem with both is vapour lock under high heat operation which is overcome with a little patience.
I would imagine a 4 barrell 900cfm projection to be the best offroad setup efi for dollars spent.
