Here's a beautiful completely rebuilt Triumph Stag engine for sale.
This auction is for the REBUILT engine ONLY. Only what you see here.
No expense spared to make this Stag 3.0-liter OHC V-8 the best it can be.
All new or reconditioned parts were used. Detroit’s best machine shop did the head rebuild, ylinder boring and balancing.
This is an expensive and extensive rebuild, ot a cheap and dirty quick fix. The machine work alone was more than $2,500. All the other parts easily totaled that much. But if you have a Stag and want to ensure its maximum value, t needs to have a Stag V-8.
Here’s the story:
This engine was in a yellow 1973 Stag that had not run for more than 20 years. It had been rebuilt once, nd not well. It appears to have died shortly after the it was fired up.
BLOCK: I disassembled the engine and had the block hot tanked and all the oilways and waterways cleaned. The block was then checked for straightness and the cylinder head facings were decked for a smooth, lat surface. All the oil plugs were removed and ALL the passages cleaned. A new water pump spindle bushing and new freeze plugs were installed. Cylinders bored .040 over.
HEADS: I had these professionally cleaned by the same machine shop and milled .010 for straightness. The valve seats, alve guides, alves valve springs, ollars, am buckets and retainers are all NEW. No old parts were reused. The cams were set to maximum factory settings as they will tighten slightly upon break-in. They will still be in spec and no further adjustments should be necessary. Assembled with thick head gaskets to ensure alignment between intake manifold and cylinder heads. ARP head bolts and studs used.
CRANK: Checked for straightness and turned .020/.030.
RODS: Checked for straightness and rebushed. New nuts installed.
BEARINGS: King Tri-metal.
PISTONS/RINGS: New County. .040 over pistons which I had ceramic coated to reduce friction and heat. Grant Rings.
BALANCING: Each piston and rod assembly were balanced and each weigh the same (documentation provided). The crank and the entire rotating mass — rods, lywheel and front pulley — were all balanced together.
TIMING DETAILS: All new non-stretch German timing chains, ew guides and tensioners, ll new sprockets.
WATER PUMP: NOS 6-vane. Correct new 180 degree thermostat (with foot; jiggle pin removed) already installed. New stainless steel heater return pipe and new hoses installed.
OIL PUMP: New AE brand.
APPEARANCE: Valve covers, il pan and engine mounting brackets powdercoated.
MISCELLANEOUS: The engine is fully assembled and ready for installation. The distributor has been tested on a running engine. The plug wires are new. Final ignition timing will, f course, eed to be set upon startup. The engine does come with exhaust manifolds, ut the studs will need to be replaced. The engine does not come with carburetors. I assembled the engine with generous amounts of lubrication. It should fire right up, o priming the oil system is not necessary.
PERFORMANCE: I have built three similar Stag engines and they were great. Fast, uiet, ool running, mooth and plenty of torque. Horsepower should be around 145, ame as the British market Stag engines. I recommend the Holley carb conversion and headers to get the best from this engine.
The Stag engine is located just north of Detroit. I can secure the engine on a pallet. Shipping is buyers responsibility.
You may be able to build a Stag V-8 for about the same amount as you can buy this one for, ut my engine is ready now. Just install it, onnect the plumbing and electrical, nd she’s good to go.
