Stroked and Blown???? Maybe I wasn't wrong when I put "porn" I the subject line :dunno:

Would not have to have upgraded injectors....it could have all other components stock but it would need to have a 4.2 crank (or aftermarket) to be considered a stroker....

I don't know if you think this is easy but......since it is out of the truck....pull off the pan and find the casting number on the crank (usually around cylinder 4) if the crank has 4 counterweights and the casting number ends in 3727...it is a 4.2 crank :dunno:

You can Goggle it but I am pretty sure you can use 1996 and up XJ shafts....I am pretty sure that is the ujoint used

I have the Magnaflow behind both the 4.0 and the 2.5....I like it

Or he went spring over when he put in the XJ diff?

:thumbsup: :thumbsup: . :MJ 1: .

Hornbrod I see what you are saying....but I would be wrong starting out..to be totally accurate I would need to have dyno results on the original 4.0. I do have the horse shoe and a 7120 head and all my personal jeeps are 5 speeds....so I should be able to sqeeze the most out of what is available. I have read and re-read as many of the forums and build articles that are available so part of my "recipe" is to add as many of the major proven components as I can in the initial build....if I am happy the 2nd will be a clone....if not I am fortunate enough to have a stock of blocks heads intakes and cranks to try something different....but...I think I will be happy with this first combo. Do the Hesco boys have a spot on a site somewhere were the post dyno results (curves)? That might be interesting reading :thumbsup: . :MJ 1: .

That is funny...I stand by the first statement....but in your temper tantrum you have read wrong and used someone else's words in the second quote....if your going to attack someone you should at least be accurate.....isn't there a 101 connector to be cleaned or eliminated somewhere in the world today?

Hornbrod....what crank was used in the 4.6 you are putting your foot into daily? The Hesco kits I was able to see all had the 4 weight...is that their standard? I personally never put Dyno on my list of things to do...2 of the motors are going in Jeeps that I have owend and driven for years...any performance gains or loses will be easy to judge.

Search it on this site a couple of members have posed nice pics to show what it should look like and instructions on how to get it that way

Actually they market add on weights to the 4 bangers to do the exact same thing the 12 weight will do...keep the mass rotating at a low RPM....helps in tight slow crawling situations.....The rotary add on gives the boys the rotating mass they don't have but want.

They use weighted fly wheels on jeep 4 bangers and on RX rotary mills so the same theory applies. As for the second question....I might .... The first will be a 2000 XJ block/intake/exhaust with a 1995 YJ ho head and the 12 weight crank.....cam and pistons both have a list (but not a decision) so far... . :MJ 1: .

WRONG fluid...get it together man

I would agree with the Giant hand analogy above

Your assuming I am seeking drag strip acceleration to get my warm fuzzy fix....I will be happier with that long strong pull that I will get on the road in 5th with a load or pulling a trailer... . :MJ 1: .

That's the wider rusted out part of the exhaust Mr Oshel

Well like I said I am building 3 Strokers....the crank above on the left is a 4 weight 3727 casting so I will not have to speculate on differences I will be able to compare them side by side... But research....logic and experiance tell me this... The 12 weight 4723 casting is a stronger crank that will offer me more low end/rpm torque...and (when touched by an installer who is knowledgeable) will give me a smoother running more balanced finished product.... If Chad or anyone else has a different opionion.....good on 'em 'eh . :MJ 1: .

Well good on Chad....but me thinks all those extra counter weights flailing around in my oil pan as I cruz down the highway will give me a warm fuzzy feeling inside every time I push down on the go-go pedal..... . :MJ 1: .

Now that my subject line got "asses in the seats" Been gathering parts to build 3 strokers...last week had a good soild 3727 (90 4.2) shipped from out west Yesterday....a farm find.....the white wale......the mythical 4723......no need to go into the specs....a picture is worth a thousand words... Maybe it is just me....but it is the first one i have ever seen......without listing the specs....can you see the difference and benefits? . :MJ 1: . :banana:

That's your first mistake.....never let off the gas!!! . :MJ 1: .

while you had the dust shield off did you have a helper push down on the clutch as you took a look at all of the clutch components and connections when they were under pressure?

not to highjack the thread but....if you don't have a face book....you can't join??? For original poster I have the same motor and it sounds vac related to me...check all the lines....extra look at ones that rub up against anything

Fluid is leaking somewhere... check your firewall below the master outside and in (above your fuses)...remove your dust shield and look at the inside of the bell housing...sometimes you can have a leak without it appearing as a large noticeable puddle.... . :MJ 1: .

Look above....COMJNUT gives you a link to a build that shows the fix
