Need a little help

[ArcticCat843]

I need some help finding the right parts to build a stroker for my 2000 Tj. I am currently taking a machining class and i have the opportunity todo all the machining work for free. This is also my second machining class and i feel pretty confident i can pull it off. The only issue is i also have a amc 360 that im going to build in the class and i wont have time to complete both. So What i would like todo is buy a block that will interchange with my 4.0 and do just the machining work on it and build it at a later date. I would really like to get all the pistons and rods im going to use so i can blueprint and balance everything but i think the main problem there is going to be money there seeings how i already have a list of stuff for the 360 to buy.

Ive been reading though some stroker builds trying to decide how extreme i want to go and im still not sure on alot of stuff.
First of all, i dont mind running 93 gas if i have to, So im ok with a little higher compression if that is what its going to take to make good power. Basically, my main thing is, i dont want to spend a bunch of money on this and then be disappointed and still want a v8. My school also has a dyno and my jeep has not been on it but a few other 4.0s have and it seems they average about 80hp and 160ftlbs to the wheels. I think id be pretty disappointed if i couldnt add 100 to both numbers.
As far as gas mileage, does anyone actually see in increase? Im pulling off a amazing 10-12 mpg now so it cant get much worse i guess. im not worried about this, just wondering.
Another thing to take into account is i drive 350 miles a week on the highway. (3 hours each way to school then i drive around town while im here) so i still need to be able todo that.

So please help me out guys
What year/model jeeps can i get the block out of? How much should i pay for one?
What machine work do i need todo, obviously bore it and mill it (how much?) and im sure ill hone the mains to clean them up but is there anything else? ANy other clearance issues or anything?
What pistons and rods should i use?
What year 4.2 do i need a crank from? (any machining need to be done to this if not damaged?)
is 180hp and 260ftlbs unreasonable?



As far as valvetrain stuff, i can decide that in a could months after i get my 360 done and have a little more money to spend on this. I have a ceramic coated header already, and obviously my jeep has the newer style intake. I will probably also bore out the TB in class, that is if the block i buy has one included. I would also probably clean up the head in the mill and do a mild port and polish on it.

Am i missing anything else?

How much do your guys think i would have into a rebuildable 4.0 block, a 4.2 crank, pistons, rods and bearings? basically a short block

Ok i think ive found pretty close to what i want
I really like this set up and it seems like it can be done for a good price

What if i did pretty much the same, only with oversized pistion? (whats the max overbore?) and then milled the block .030-.040 which would give me really close to zero deck height. Which i realize would bump the compression up a little correct? but it would also be tighter so it would prob still run on lower octane gas.

Then i plan on a aftermarket cam and valve springs but like i said i can do that later.


One more question tho, why the piston dish? and what machine is used to make this? Is it done with a bridgeport style machine? because i believe i have access to one of those. But according to the price list in that thread it was only like 60 bucks so i guess its not a huge deal.

What kinda power do you guys think that would put to the wheels?
Anyone see any problems with my plans?
