Question small block in a jag

I recently run across a good deal on a jag. The engine has been on fire, so my first impression is to pull the v-12 and put in a 350 or 383. Any body ever tryed this? I was told that it had a th-400 transmishion, and dana44 rear end, but haven't verafied that yet.

Pick up a copy of Mike Knell's "Chevrolet TPI & TBI Engine Swapping". There is an engine & trans swap in this book in a Jag. I ordered my copy online from Steve Smith Autosports <a href="http://www.ssapubl.com" target="_blank">www.ssapubl.com</a> Good luck.

the jag does have a th-400, boltpattern does however not fit chevy.. the bolt pattern is a lot smaller.

the rear is dana-44 but.. the jaguars from before 90 have a 10 spline pinion, and not 26 splines like the american version..

but the car handles like a dream and you can fit even a big block in there. a Chevy small block even weighs around 100 lbs. less than the Jag OE. inline 6.

try and do a google search on jaguar v8 chevy conversions and youll get about 150 useable hits, both with bolt in kits and tips on howtoos if you do it your self

Thanks for the help, I didn't think the traney would bolt up, but I figuared a chevy th-400 would slide right in with no problem. We picked up the book today, but I havent had a chance to readd it yet, becuse this is my brothers project, and I left it at his house
One more question, how much will the v-12 and tranny be worth? It's a low mile care, and was running before the fire, but the wiring is now tosted?

Jeff,
Just out of curiosity, what year and model are you talking about? The XJS or XJ12?

If its a low mile car and ran well before, then just get a wiring harness instead of changing everything. Painless or Haywire might have one in stock or they will be willing to custom build one. You could always go rob one out of a donar car. You might even be able to get one from a Ford dealer/parts supplier since they own Jaguar.

Hi Jeff, Have seen 10 conversions in recent times, all have been 350 chev conversion.
I live in New Zealand the Jag XJ6's are real cheep here and so the 350 is a logical choise as we pay moon beams for Jag parts..

Cheers
Sandman

the car is a 1988 xjs. We have a 400hp goal for the car and I think we can do it cheaper with a v8.

I had a 86 jag XJS. Best thing you could do is put the chevy engine in it. Contact "Johns cars" or "Jaguars that Run", they have a internet site and they advertise in Hemmings motor news. They have done thousands of these conversions and sell kits and or components to do this conversion. They even sell a wiring harness wired for the chevy that plugs into the jag firewall plug. A 350 chevy engine in the xjs makes these a nice driving, reliable car with more power than the factory v-12, which by the way is only 326 cubic inches.

i put a 327 in a MGC back in 76-80. Plan on changing every part in the entire ****ing car. It took years and every minute and dollar i had to roll it into a ditch in Okmulgee oklahoma in sept 1980. Left a brand new engine hanging over it under a tree cause i couldn't stand to be in that 90 degree 90 percent humidity another second. sent the title to my friend when i got back to reno. anybody seen this car in OK? It had an M22/Hurst, narrowed pontiac rear and flat windshield. sure wish i'd owned a truck back then instead of a dodge colt!sfb
