ok i got an 86 2.8 beast :roll: and though it runs prity good i know the

bottom of the motor isnt in that great of shap and the way i drive , it aint

gona last long. i need to up grade wile i got the money and would like to

do the 3.4 swap because it is a direct swap and i can do it relitivly quick

but what I'm having trouble with is locating a sutible replacement.

I was orignaly gona get the gm HT 3.4 factory replacement but that is

gona run me close to 2 grand which almost blows my entire budget

(budget is $2300)and I'm not big on the getting the a J-yard motor of un

known orgin but it looks like that is what I'm gona half to do.

 

so where is the best place to get a good engin from ?????

http://www.pullapart.com Flat rate of like 140 or something like that for a 6 cyl

 

...... If I'm correct isn't the caddies northstar the same bolt pattern as the 2.8??

I also need to replace a 2.8 in my 86 that is blown. Been considering a jy 3.4, I will be watching this thread with great interest becouse the info seems really good on this site.

I'd use car-part.com to locate a junkyard near me. Then I'd research each junkyard's warranty and determine which is best.

Or,

I'd hunt down a whole car that had a running engine (maybe a rear end collision or the like) which would allow me to determine the shape of the engine before buying and swapping.

I was looking at swapping my rodeo engine a while back and found this list of swaps... now I don't know if this holds true to the Jeeps 2.8 but it list the 3.4 3.8s and the isuzu is a 60* motor..

i for got to mention that this was also a possible option . I found this site a couple of years ago and they have alot of stuf for the 60 V6

1)a 3.1 stroker kit $500

and build 1 of my spare engins

 

2)a 3.1 stroker short block $1100

purchas a cam and gaskets and put my curent heads on it, but still alot of money (curent heads are rebuilt largevalve heads)

 

3) 3.4 short block $1200

 

 

in the end it is still reaching the near cost of the GM HT 3.4

The GM 3.1L or 3.4L out of any rear wheel drive vehicle (Camaro, Firebird, S-10, etc) will work.
