84 blazer build-up questions

okay i have a whole bunch of questions for everyone out there.my friend is away and his mom wants to fix his truck up for him as a suprise for when he gets back. here are the specs of the truck. it is a 1984 k-5 blazer with a 305 engine, a 208 transfercase, and 10 bolt axles front and rear. i am unsure on the transmission but i know it isnt a th350. what could it be??

the kids mom is going to finance the whole thing and she wantws me to do the work for her. now the kid wants to run 36-40 inch tires.

the kid wants a 4 and 3 lift with 3 on the body and 4 on the suspention, he also wanted to put a 350 in it. i know the axles have to be upgraded to but i was thinking of 1/2ton or 3/4 a dana44 12bolt combo or a dana44 14 bolt ff. i talked to his mother and she is willing to buy a crate 350 so thats no problem and i know about the lifts what i need and what not. i was wondering if the trans or t-case need to be replaced or will they hold up?? also any input would be great.

Re: 84 blazer build-up questions

Is the trans a 3 or 4 speed?

What kind of wheel'n is the truck gonna see? I've seen 1/2 tone axles take a pounding on 40s in the mud.

Tire size pretty much dictates the other mods you do to the truck so that sould be the first decision made. I would stay away from 3" body lift any way I could, regardless of tire size.

And I've seen trucks on 8" blocks front and rear.

That doesn't mean I want to drive around in them, or off-road with them or stand too close on a windy day.

If the madre is footing the bill and the kid wants 40's then call that cat in houston and buy a set of 4.56 geared military axles (d60,14ff) Last I saw that guy was selling them for about 1500-1800 a set.

If not, stick with 36's and the 10 bolts. Just my opinion.

If the tranny is a 4-speed auto then it almost has to be a 700r4 unless someone got tricky and put a 2004r in it. If it is a th400 behind a 305........ I'll kiss your ass or the motor was replaced.

If it is a 4-speed and not an auto you shouldn't have any problems out of it.

If it is a 700r4 and he plays hard.... expect trouble and then replace it with a better 700 when it blows up.

The Tcase should be fine..... Until it blows up. Then replace it.

Re: 84 blazer build-up questions

I would go with the body lift on a blazer, to fit 40's your gonna need the 4 and three combo along with cutout fender flares or they will hit. Over 4" susp lifts on a blazer may start to cause bad angles at the tcase. I would just either look for a rebuilt 700r4 or swap in a th350. 84 is a bad year for the 700's. get a 3/4 ton 10 bolt and a ff 14 bolt.

<font color=blue>If my mom gave my the money to do that, I'd say hell had frozen over[img]/wwwthreads_images/icons/tongue.gif[/img], All I'm saying is that if I came home one day and someone had changed my truck as much as we're talking about here, And it wasen't the way I wanted it, Or MAYBE even if it was, I'd still be pretty ticked off. Because it's MY truck, And nobody has ANY right to do anything to it without my consent! Think about it this way instead, You take you truck to a shop, To say, Change the diff fluids, And while there're at it, The deside your axle is messed up, So they just put in a new one, And bil you for it, Ignoring the fact that maybe YOU whould want to do it yourself, Or perhaps take it to a differant shop to have it done, If in fact it was messed up, And did need to be replaced.

Re: 84 blazer build-up questions

okay in reply to all the questions, first he realy wants to run 38's and and in reply to wait till it blows up and replace it she doesnt want him to come back and when he takes it in the woods something will blow up she wants the stuff that is gonna be weak replaced now. and as for not working on it because he might want to do it. the kid doesnt know anything about trucks. even if i waited till he got back he would give me the money and i would still do all the work on the truck, and to make sure i get it exactly how he wants it he has told me everything he wants done to it to find out how hard it will be before he left so i nkow what he wants done. oh ya the trans is a 4 speed automatic.
