“Spit-6 Or Dr. Frankenstein”
$7500 OBO
This 1980 Spitfire convertible has a rebuilt 1973 Triumph GT6 2.0L pushrod inline six cylinder engine. The front shock towers are also from a GT6 to handle the extra weight and heavier-duty springs.
The 4-speed transmission was professionally rebuilt by Quantum Mechanics in Connecticut. He also tested the J-type overdrive and pronounced it solid. The differential is a 3.27:1 for better gas mileage which was purchased from a member of the “Triumph Experience” forum. (The 6 cylinder engine creates more than enough power to propel the car with alacrity using this diff.) I also have a 4.11:1 differential for those who want more “poke”.
The engine pulls strong under all circumstances and the J-type overdrive works flawlessly. She happily runs at 70 mph all day.
All lights and gauges work except for the Odometer, which reads about 68K miles. It read that when I got it and I was unable to make it functional.
The engine was rebuilt from 2009-2010 as money permitted and included the following:
Block and head hot acid washed and magnafluxed. (Machine work by Ewing Machine)
The head received a 3-angle valve grind with:
New valves (Stainless on exhaust)
New rocker shaft
New rockers
New springs
New collets
Hardened exhaust seats
Bronze valve sleeves (perpendicularly trued within the OE iron guides)
Delrin spacers instead of shaft springs
Ports matched with manifolds
The block was bored .020 over. (Had previously been bored @ .010)
It was align bored and all rotating parts were balanced.
Micropolished crankshaft,
New pushrods
New drilled tappets from Jigsaw Racing
New flat-top pistons with new wrist pins
New bearings throughout
Rebuilt brake master cylinder.
New clutch and throw-out bearing
New oil pump
Spin-on oil filter adapter
Bosch 55-amp alternator
Rebuilt distributor and Crane breakerless electronic ignition.
New TRF ignition wires, cap & rotor
Aluminum radiator with electric fan
Rebuilt carbs with large heat shield
K&N air filters
Aluminum coated OE exhaust manifold
Custom made muffler system
Rebuilt rear leaf spring with Teflon spacers
Fuel tank boiled out and leak repaired
Fuel evaporative system reconnected.

Body and Interior
NO RUST. Anywhere. The car is a great “10-footer” and gets compliments everywhere she goes. Get closer and you will see the blemishes in the paint. I dreamed of painting her either Damson, or even candy apple red.
The bulkhead was stripped and resprayed where brake fluid had leaked and ruined the paint Brake system now using DoT 5 silicone fluid.See my Journal entries.
Re-veneered dash with bird’s-eye maple. (Used “Gorilla Carpenter Glue” which was a mistake; some cracks have surfaced. Should have used regular carpenter’s glue.) Still looks good and gets compliments. Wants a new dash top pad. Was recovered in vinyl by the P.O. & looks OK, but I always wanted to replace it. Windshield should be replaced as it is original and seems to be de-laminating in the bottom right corner. That would be a good time to do the dash pad and the window rubber.
All gauges were cleaned and retrofitted with LED bulbs. A Smiths oil pressure gauge was added to the center dash panel.
Sony AM/FM/CD player with USB and jack inputs.
Upholstery and carpeting wants re-doing but is not threadbare by any means.
New (2009) seat belts and retractors.
Driver’s exterior door handle should be replaced.
Convertible top was new in 2009 and the clear plastic is in excellent shape.
Four new tires on reconditioned (blasted & resprayed) OE steel wheels.
Halogen headlights with separate relays for high and low beams.

I also have:
A matching painted detachable factory hard top with excellent glass.
GT6 window regulators and ¼ windows with excellent
chrome. (Not installed. Need new door window glass from
Canley’s in the UK.)
Original tonneau cover in good shape.
Extra speakers for under the dash. (Not installed)

Even with it’s faults, this car is truly under market value considering all that has been done. There is still a lot to do, but all the “heavy lifting’ has already been accomplished.
