Thread: Efi or carby

Depends on which carbies are fitted. The original twin carby setup of the rangies were great, I never had any issues until I had the motor swapped to a p76 with a 350 holley - this was great for street but rubbish offroad.

Never had any problems with mine. I usually switch to petrol for offroading for the extra power. I've been on some pretty rough stuff.

Had plenty of problems with other stuff, but not that

Probably better fuel ecomomy with EFI, and the carby's can be hard/expensive to tune.

1 of the rangies that I have been looking at has the P76 engine with a 600 holly, I don't want fuel running to the front or back of the carby and floading or stally out the engine.

Guy so in your experience this would be a bad combo?

Thanks,
Jason.

If you do buy it and want to change over to the strombergs, I have a set + manifold that you can have.

I know nothing about the 600 Holley. The P76 was a fantastic improvement but the holley created all sorts of dramas. Some people have apparently been able to overcome the flooding issue but I wasn't and none of the workshops that I deal with were able to either. You can lower the float level which does improve it a bit, but you still get to a point where it floods. Some advise to turn it round 180 deg but this just means that it floods going down hills rather than up. There was/is an offroad kit available but when this was fitted to mine it flooded going down hill. If I had to choose when I'd prefer it to flood and stall it'd definitely be up hill, loosing power, steering and brakes going down a hill is not fun.

I suppose it depends on what sort of 4wding you intend to do with the vehicle, if its just light tracks and beach etc, there shouldn't be any issues but if you're wanting to do steep technical tracks eg Glass House Mtns etc personally I'd steer clear of the Holleys.

Cheap EFI Rangies do appear occasionally.

Or transplant a disco engine and harness into the rangie. v8 discos can be had for as little as $500 unreg,unroadworthy.

I know of a disco thats about to get a heart transplant and since Im pulling the engine can probably arrange for you to have it complete with the relevent harness for a chip in at the cost of the replacement heart and something to encourage me to not take the existing v8 out with the high speed tools as opposed to the proper spanners.

Get an Edelbrock dual plane manifold and a Rochester Quadrajet. Follow Rochester's instructions re modifications for off road racing. Get the book Rochester Carburetors, Doug Roe & Bill Fisher, HP Books. Look at http://www.cliffshighperformance.com...history_1.html.

Thanks Brian Hjelm, Debacked was just telling me thats what he is doing on his project.
