Engine conversion
Just bought a 1974 XKE Roadster that had the original V12 removed and a conversion to a chevy engine started. What is the best chevy engine to complete this conversion with a manual transmission?

Good luck with the manual (mine is an automatic). Went with a 327, iron block, but likely would have preferred an aluminum block engine for weight.

Get the level 3 and that will be bullet proof! |
Agree with the LS, huge advantage with regard to intake clearance if you get something like an LS3. Mated transmissions are better too. Issue will be electronics. Try Jaguar Specialties: Jaguar V8 Kit

XKE
I checked out the website and spoke with Andrew. They do not offer anything for the XKE.

My fault, John's cars has the kit for the XKE. Mostly engine mounts etc. Jaguar Conversions from John's Cars Also you can get aftermarket fuel injection for older engines. I'm using a Holley Sniper with matched gauges (you need an adaptor for the speedo and tach though as the Holley's are 1/2" too small). Engine auto tunes, its pretty cool (I also went with the matching electronic distributor), car starts like a dream. I should have updated pictures in my thread shortly.

I agree, if I hadn't started out trying to make the 327 work I would have gone LS, in the end it likely wouldn't have been that much more expensive and the engine fits better (I'm having major clearance problems which will require I modify the bonnet). The only issue with the LS is that it isn't a pretty engine. But, by the time I realized the 327 wasn't ideal I'd already sunk a ton into it. Still with the Holley EFI, heads, and intake I'm getting an estimated 450HP which is god awful scary in an E-Type.

you should have named the post 'how to halve the value of a E type', engine swap to a chevy? what are you thinking???????
Its your money but talk about sacrilege, that has to rate among the worst offenders. Whats your next project, a chevy into a model T Ford? |
Once a conversion is started, particularly a Chevy conversion, going back to a Jaguar engine is wicked expensive. The poster bought a car with a Chevy engine conversion started and it is simply much cheaper to finish it. The V12 is kind of a pill of an engine anyway, it was supposed to be injected (and eventually was in the XJS) but in the E it used 4 Stromberg carburetors and it is nasty to keep running, lacks power particularly at the low end, and isn't very attractive (thanks to the smog plumbing), oh and it is wicked expensive to buy or repair. A modern V8, particularly the LS as noted above, is a dream in comparison and if you want to drive the car distance is a far better choice. My own car had the 327 already in it when I bought it, but, were I to do it over, I'd have either swapped it for a Ford engine or an LS. I'd just thought it far easier and cheaper to fix the 327 not realizing that the engine was beyond saving until too far along in the process.

To re-convert it back will increase the cars value way beyond the cost. What has been done is like painting a piece of Chippendale furniture, there should be a law against it

You are right. The reality is a 1974 is not commanding the big money the 1960's will command as you can buy them for $20-50K and only when they are concourse level to they go for more. If you convert it I doubt you would make any money on it. Thus if he wants to just drive a reliable XKE since it is already set with a Chevy then the LS Chevy would be easy and provide 400-500 HP and drive all day long to 300,000 miles trouble free and would only cost around $5-7K. To each his own. For me my 1963 3.8s was built to be a daily driver so the LS1 is perfect as I have put 80,000 miles in less than 3 years trouble free. The really early Jag convertibles I would agree would be valued more stock but this is not an early one and then when you have that stock classic they are more collector cars that you cannot drive both reliably, nor as comfortably and if you drive them too much their value goes down. Thus it all depends on whom owns it and what they want. That is why the younger generation wants more restomod classics as they want the luxury, reliability, power of a new car with the looks of a classic and at Barret Jackson auctions the dollars are moving more on that trend with quality restomods commanding more than stock in many cases. |

Funny, a 74 shell is around £30000 in the uk with restored cars to £125k+. You cant tell me that there isnt some serious money to be made by returning it back to its former glory. As for comfort and reliability , since when have they ever been a factor with classic cars, breaking down is just par for the course. If you want reliability buy a new toyota
Maybe in the UK but it is not too hard to find cars like this for 1974 Jaguar XKE for sale right now for $26K http://images1.americanlisted.com/nl...d_28029413.jpg or this for $32,500 http://images1.americanlisted.com/nl...d_28108371.jpg The Jaguars that command big money are all 1960's and then the more limited models. To each his own. I know many Jag purest hate to see a restomod but the reality is not everyone wants a stock car. This person has a V8 Jag and just wants an replacement V8 for not a lot of money. I stock Jaguar is not the most reliable car so for some whom will drive it many miles they would rather have a more powerful, lighter, more reliable V8. If his car was a 1960's that would be a different story and primarily if the car did not need anything but an engine swap then it might be worth going back to the V12 if he did not want to daily drive it but rather sell it. In the US the car really needs to be one of the years that will command in the upper 100's to be worth that endevour as those cars that command that price are concourse level and the cost to restore to that level can easily be $60-$90K+ not including the cost of the car so unless it will sell for over $150K you will not make any real money. People own the cars they want and modify them they way they want for their personal enjoyment. If you want an investment cars are not the best place to put your cash. My classic restomod 3.8s has full electric seats all leather with headrests & picnic tables, AC, power steering, blue tooth, WIFI, back up camera, tire pressure monitoring, custom stereo with subs, does 0-60 in 3.95 seconds, gets 20 MPG, is comfortable, quiet, smooth ride, and does not break down; I have put over 80,000 miles without any issues can your classic do all that? |
the simple solution is to stick it in a container for £1500-£2000 and ship it over , its not difficult. sorry but you will never convince me that defacing a work of art like the e type with a chevy engine is ever going to be justified.

Convince you?

To put a different V12 engine that did not match this car would be moronic. A $50000 investment that might return $30000. The frame was not altered and could accept a V12 if anyone was that ambitious. The car needs alot of work to the interior and the engine. The body and frame are in excellent condition. Seats are in very good condition. It has a vinyl covered hard top that is also in excellent condition. I love the car and plan to enjoy driving it for a very long time! Thank you for the common sense and support Enderle! As for the Chippendale, if I choose to paint it, that is EXACTLY what I will do! |
