How long since it was rebuilt? I would take it back to who did the work and make them warranty it.
For 16k u couldhave had a replacement Jag motor put in at dealer.

 

definityl shud of bought the jag engine.. and it wud of lasted you another ten years ..

 

I secretly would love to find a dead s-type and stick a Ford 4.6 in it. Maybe even sticking in a 6 speed tremec.

Converting it to a 4.6 would not be that hard nor expensive compared to regular Jag replacement.

I'd love to have a really "tough" Jag that I could beat on. Imagine an s-type showing up for a local drifting competition....full V8 sound and tires wailing for help. Then when you are done and you step out of the car in a business suit and helmet. Ha!

 

Yikes! We sell rebuilt V6 engines for less than $4688 exchange. I would have bought a another S-type for $16K.

 

cosworth, you are on the right page man

 

I've seen the old 5.0 pushrod in the older XJ6 bodies. The 5.0 is narrower, but is pushrod. Bulletproof but the 4.6 seems more "Jag". Although if your state/locale has lax emissions a nice carb swap would be dead easy with a 5.0.

Understand that "anything is possible with the right budget."
