Chevrolet small block power and reliability for the sexiest cars ever built.  This kit is for all 1971 to 74 V12 coupes and roadsters.  Six cylinder cars require different kits – go here.  My conversions are 100% bolt-in, absolutely no cutting, welding, etc. required, all instrumentation functions as original, thus your collectable piece remains unscathed and you can enjoy its use.  Kit is for left hand drive only.

The V8 E-Type weighs approximately 125 pounds less than its V12 predecessor when using an all iron V8.  The center of gravity is changed slightly rearward and enhances the handling without upsetting the ride.  Serviceability, parts availability and cost, fuel economy and reliability, are just a few of the pluses.  Drive it anywhere and back!!!   It all slips under the stock bonnet to keep it under wraps and sneaky.   GM Fuel Injection will clear the hood so you can be ultra-cool.

The conversion kit includes:

TBI & TPI Notes:  Presently, all GM serpentine drive accessories will not clear the frame rails and/or hood.  If your TBI or TPI came with serpentine brackets and accessories (alternator, compressor, power steering pump, smog pump), you'll have to swap the brackets for an the earlier style of brackets that use multiple vee belts (you can reuse the accessories).  The brackets that work are on any 68-87 carburetted motor with the long A/C compressor on the left hand side.  Aftermarket setups may work, but I do not know of any.

LT-1 Notes:  LT-1 accessories also will not clear the frame rails and you do not have a water pump pulley to run the multiple vee belts.  To use this motor, you would have to custom make serpentine brackets that mount on the LT-1 AND fit inside the the frame rails.

For Fuel Injection motors, we suggest an aftermarket harness from a specialty shop.  We have used Howell Engineering in Michigan (810-765-5100) and Dr. K in Alabama (205-543-7165), both with success.  We do have fuel pumps and Oxygen sensor bungs in stock.

Your transmission choices are the 4 or 5-speed manuals, T350 or T700 automatic overdrive.  The T400 is not recommended.  The automatic conversion is easier since you do not have to fabricate shift linkage (4-Speed only, 5-Speed linkage has integral linkage).  You can convert your manual shift car to an automatic by fitting an aftermarket or GM passenger car shifter to your console (or console from an automatic E-Type).  The GM 6-speed has not been tried at this point.  It has no provision for mechanical speedometer drive and the setup to drive the speedometer is pricey.

The automatic swap requires 20-30 hours (exclusive of detail work such as repainting the frame rails) and no special tools are needed.  For manual shift conversions, add 5-10 hours for shifter and hydraulic clutch installation.  The manual kit is for a 10" clutch and it includes the special bellhousing, clutch fork and arm but not the clutch or the shifter.

T700 Notes:   All T700's have torque-convertor lockup and it must be hooked up to prevent damage to the transmission.  John's Cars offers ELECTROLOCK™, the simple setup to lock-up a T700 torque convertor for maximum fuel economy. Very easy to install – no drilling, tapping or machining required.  For T700 trans to 1992 (not 4L60E).  The kit can be installed with the trans in the car.

Please call if you’d like help filling out your order sheets.  Please call – remember my fondness for phone tag plus I may not be able to get it on its way if your order is not complete.  If you have any questions on the conversion kit, please call or email them to xke12@johnscars.com.  Prices subject to change without notice.

The E-Type Conversion order sheets are JPEG images (about 185K each) so it will take a minute or so to load.   Print it out from a Laser, LED or ink-jet printer only – dot matrix printer will be useless.  Make sure your print margins are set to .50 inches or it may not fit on a page.   

Note: Given the proprietary nature of my conversion kits, I do not allow the return of a conversion kit for any reason.
