Does 6.0 have same bell housing bolt pattern as the 5.3? Ie there anything majorly different between the two, in regard to swapping 5.3 for 6.0?

 

yes, a good running 6L jag V12 , is easily worth $1000.bucks.

best i seen was $1300.

not quite sure if bell pattern is exactally same, but most important would be the alignment dowels are the same as GM,distance from Crank center line to dowel, i think they are so any mods to bolts should be easy to do.

 

NO, my 6.0 bolt pattern is different from my 5.3 (1994 6.0 and 1989 5.3)

I had the 6.0 block re-drilled so the BP is the same a the 5.3. Cost a hundred bucks from the guy I bought the engine from.

BTW I payed 4K for my 6.0L

There are many advantages to the 6L the heads flow better the longer stroke is good for more torque and with a 93mm bore 6.5L is easy.

If you do buy it make sure you get everything. The differences in ancillaries are enough that they are not easily interchangeable - for example you can not bolt the 5.3 injector rail to the 6L and the harmonic balancer is different.

 

its funny that the only good running 5.3 in the US is about to be swapped for a 6.0

 

Now now...my 5.3 runs great! It's the blown transmission that's the problem!

 

mine runs great, and 4spd overdrive auto is perfect.

 

if you need a trans i have a jag turbo 400 in my shed for 100$

 

And I do have perfect transmission, that was freshly rebuilt before I got the car. I even welded in nice drain plug in the pan... CHEAP, everything must go!

 

I was just thinking out loud, mine does run like a bat out of hell.

 

Imagine how it will go with a 6L and manual WOW

 

I know where I could get another 400, but if I'm going to pull it out, than I might as well convert to a 5 speed. I already have the tranny, now I need the rest. I'm just a little busy building a car for my wife!

 

Ah the wife, so glad i don't havr one of thoes. When i use a computer instead if my android i'll send you a message about the parts needed

 

My 5.3 also runs perfectly. It just leaks like crazy! Still sorting it out. Perfection is a state of mind.

 

This is how cats mark their territory.

 

i need someone to take the TH400 off of my porch before it goes to the scrapyard.

 

I'll post mine on ebay soon, hoping for $300.

 

when i moved from Florida to Texas, i junked/scrapped 3 T400 trans, 2 T 350 trans, best of all, 3 complete Jag V12 engines , one carby type, 2 FI types, plus lots of jad bits ,ECUs, injector drivers,ETC.

couple Chevy V8s, along with GM 700R4 trans.

i got $25. each engine, $10 each trans, around $25-30. each chevy.

remember junk is just junk/scrap, OH yes, unless some one needs it, most stuff i had for over 10yrs.
back when you said (Jaguar V12) NOBODY would touch such junk, now it seems they are making a come back,Go figure that one out.

 

One collector once told me that the highlight of my XJS' career will be when my 15.5 y/o son puts it in the ditch. I tend to believe it

 

i just came back from a local car show, nice people interested in my custom Jag, lot of questions and comments all good.

one guy says he knows of a junk yard in south texas, that has 11 jags all piled on top of each other. thats sad

 

the highlight of anyones car career when something incredibly stupid and it ends in a crunching crashing firey mess!!!!
