I have an 88 Toyota truck with a 4 cylinder in it who ever put in in there did some below par work would like to swap engine tranny rear end etc. But don't know where to start on need of some helpful advice

 

A problem well stated is almost solved.
Wanting to swap is not a problem.
What is keeping you from doing what you want is the problem.
What is your problem?

 

Is it better to put a 6 cylinder in or a 350 and wel I need a new tranny and what's the good choice fer a rear end

 

There you go!
If I were to do a swap, I would do a 3.4. Toyota reliability, more than enough power and compact enough for that gen's weight and size, and electrical should be simpler to convert, being from same manufacturer.
I suggest you look at 3.4 installs on the forum. I saw a picture of it in a first-gen 4runner and it does not look as cramped as a 3.0.
I don't think there's any issue with the transmission.
The rear suspension of course may have sagged, but there are lots of solutions discussed in this forum. Use the "google" search option, not the "post" or "thread" search. The latter two are lame.

 

Depends entirely on what you want to do with it

Drag racing?
Rock crawling?
Mudding?
Show truck?
Daily driver?

For a show truck that gets 200 miles a year, sure, drop a 350 in it

For a daily driver that gets thousands of miles a year, I like the 4 cyl for it's reliability

 

I ganna hunt work it has a 5 inch lift setting on 35x12.5

What might this cost to swap engine and beef up rear end

 

So it has 35’s now and your saying the 22re isn’t doing a good job, PREPOSTEROUS!!!!

Just kidding jake but you really need to give us more info, are you doing the swap? Have connections in the auto world? Budget? Is it geared now? Etc etc etc etc.

 

A friend who went to uti well be helping me with swap don't think anything had been done to the truck other than the lift and the engine wad replaced once and who ever did that only put half of the bolts back in the bell housing and one bolt in the starter add I found our when I replaced the clutch the ac pump is resting on the frame and I wad hoping to do this fir about 7 grand if possible don't know much else about the truck or what I'm getting into this well be my first project
