what year truck???military_stang
Doesn't really matter at this point what year it is. a stock truck (of that year) will have about a 37:1 crawl ratio.here is the breakdown of gearing assuming you have stock Ring and pinion gearsStock single case: 37:1Single case w/4.7: 76:1Dual stock cases: 84:1Duals w/4.7 in one case: 173:1Duals w/4.7 in both cases: 356:1so, you need to decide what type of driving you want to do with your truck, and change the gearing appropriately. in most instances dual cases with 4.7 gears in one case will be enough to get you by, but some of us like to get extreme
4.3 and 700R
Just make sure you buy from Marlin. The quality and service is next to none!
If you are serious about the 4.3/700R4 combo you really need to consider either putting the 4.70 gears in the rear case or at a minimum going 23-spline for added strength. The 23-spline was originally for the Turbo model and I bet the 4.3 will have more power than that. The additional cost is minimal when compared to the reduced chance of failure. In my opinion, if you are planning to build for more power with an automatic, you would probably be OK without the 4.70 gears. The automatic will allow you to crawl just fine with dual cases with stock gears in both and the stress on the drivetrain would be less.I have heard that with an automatic, you can't stop the rig with gears lower than 100:1. The brakes can't handle the torque. This gives you an idea of the gearing you would have.I would advise a dual ultimate and keeping the 22RE unless you are playing in deep mud where speed is the only option.LOW GEARS ARE MUCH MORE IMPORTANT WITH STANDARD TRANSMISSIONS THAN THEY ARE WITH AUTOMATICS, ESPECIALLY IF YOU HAVE ADEQUATE HP.
Whats your reasoning behind wanting a 4.3 and 700R so bad?
Excellent points... yeah I was thinking about this this morning when I was preparing to make the New Years sale purchase... I obviously only want to do this once and want to go into a ~$1000 investment knowing that it will handle some changes in the future. In order to get the sale price, it looks like I'm stuck with the 21 spline input. This is a pain in the ass.
Power and driveability. The 22rE sucks...
I have seen a 4Runner on 37 inch tires run 80 mph with a mostly stock 22RE. My stock 22R will run 70 mph most of the time without problem. Durability and Reliability are also things to consider. If you are going the HP route rather than gearing, then you don't need a 4.70 gearset.
Have you considered other options? look at the entire engine spectrum. Not just 22RE's... 3RZ, 5MG, 7MGwhat about a newer 3.4L? those are an excellent engine.
I'm not anti 4.3, I just see alot of better options rather than the 4.3LStaying Toyota engine / tranny is just a better option for easier buildup purposes and availabilty of aftermarket support.
