Has any one ever been able to spin 33" tires w/ 4:10 gearing in Hi Range with Center Diff Locked and a True Track in the front and a Detroit in the back in a Disco II w/ a 4.0L Petrol Engine w/ 60K miles on it in snow or deep mud? Engine is in great shape, no leaks, doesn't burn oil and followed the Land Rover Preventative Maintenance Program diligently. I am getting 300 miles on a tank. Also the truck weighed with 2 adults 3 children under 6 and one Boxer dog, gear, groceries for 1 week, clothes for a family of 5 for 1 week, diapers for 1 child for 1 week, fridge, Awning, aftermarket bumpers, winches-(steel cable on the front and synthetic on the back), dual batteries, swing away tire carrier (High Lift and 3 20L Jerry Cans mounted to it) 90 Watt solar panel, RTT, Sliders, drinking water system, 20L water storage, aluminum Safari Style drawers ect weighs in at 6,000lbs.
I haven't been able to spin my tires ever since I threw the 33's and lockers in, even with the 4:10 gears (for the past 2-3 years). The engine revs up to about 3-4K RPM and then nothing, it just stays there. I have to put it in 4Low just to get some wheel spin which sucks because the tires won't spin fast enough to clean the lugs out.
I am thinking about switching the engine out for a 4.6L to get some more power or possibly going with a fuel injected 327 crate engine. Any thoughts on this?
Is there that much more power in a 4.6L?
I have upgraded the rear axles, but haven't touched the front ones yet. STill waiting to decide what motor to put in. If I go with some sort of a 327, or a 350, or a 383, or a 302 conversion, I will more than likely end up getting rid of the entire drive train and going all custom complete w/ a 3 suspension link set up. If there is quite a bit more power in the 4.6, I will probably keep the drive train as it is now. I am in mostly deep snow and thick slimy mud, not a lot of rocks, although there are some trails further west that I have encountered some long rocky stretches, mostly the size of soccer balls, not really anything like Utah where there is all solid rock stretches. These trails here have rocky, sandy patches but for the most part it is mud and snow.
Thanks for puting up with the long read.
