Alright yota guys 90 pick up 22re with a fresh rebuilt w56 on 33 10.5s can't get over 50mph sounds like she's wound right out in 4th put in 5th loses all power talked to previous owner said he never had an issue going over 50mph. what's the issue... thanks in advance

 

What gearing in the axles?

 

 

Haven't done anything yet was looking for pointers where to start

 

Melrose not sure what has been done to it as far as the things you listed I just got the truck had the trans rebuilt now this trying to get the kinks worked out

 

If you just got this truck, I would start out by doing some maintenance to get a baseline.

Is the "Check Engine" light on?

First, to see where the health of the engine is, I would do a compression test and also check the ignition timing. Checking for vacuum leaks is a good idea too. Is the air intake boot cracked?

If the spark plugs, distributor cap, rotor, spark plug wires, air filter and fuel filter are in poor or unknown condition, I would check and replace those as necessary.

 

First, 50 mph on 33's is more like 60mph. (About 57 mph if my speed app is anywhere near correct)

I'm running mine on 33's with the factory 4.11 diffs. To hold 65 uphill I usually have to twist it around 3grand in 4th.
5th is useless unless going flat land, down hill, or putting around on back roads.

I know that when I put the Catalytic Converter back on my truck it definitely hurt power. A lot.
I would check timing too (as stated before) and for anything that would cause it to run lean (Vacuum leaks, etc)

You are looking at what, 115-120 HP out of a stock 22RE In really good shape? Probably more like 100 out of one with some miles on it.
It's never going to like hills on anything over a stock tire size.

Embrace the slow.
It's the way of the 22RE.
