yeah see... so there you 3L V8 slaggers LOL, I knew there was never any thing wrong with em

Oh yeah???

"(1) The long simplex roller link chains combined with inadequate engine maintenance and factory specified 7,500-mile (12,070 km) oil change intervals. The chains could last less than 25,000 miles (40,200 km) resulting in expensive damage when they failed;
(2) The inadequately sized main bearings in the early OHC 2.5 litre V8 design with short lives, changed in the 3.0 litre design;
(3) The aluminium head warpage due to poor castings, head gaskets which restricted coolant flow, leading to overheating;
(4) A multitude of water pump failures relating to poor drive gear hardening, prematurely wearing out the gear and stopping the water pump.

And in some cases, overheating was caused by clogged waterways in the cylinder block which were found to be filled with casting sand left over from manufacture."

So there...

prove it... and Triumph never built a 2.5 V8, a 2 liter super charged straight 8 yes V's only ever it the TR8 and stag bothe threeeee liters... bloody yank tank lover

They did do a 2.5, it's what the 3.0 was based on. Come on, I'm a spring chicken and I know this

I will now access my Triumph bible to find out... but if so, what was it in?

That's a good question I do recall a TR concept with a 2500 V8, I may be imagining things.

Here's some info for ya:

"Harry Webster had also already started development and testing of a new unique, all Triumph designed overhead cam (OHC) 2.5 litre fuel injected (PI) V8 to be used in the Stag, large saloons and estate cars. The vision was to allow Triumph to compete in the V8 marketplace. Under the direction of Harry Webster's replacement, Spen King in 1968, the new Triumph OHC 2.5 PI V8 was enlarged to 2997 cc (3.0 litre) to increase torque and the troublesome fuel injection dropped in favour of dual Zenith-Stromberg 175 CDSE carburettors to meet emission standards in one of the target markets the USA."

Always glad to help!

I don't think the 2.5 V8 actually went into production? While the V8 was originally developed as a 2.5, it was enlarged (by reboring) to 3.0L late in the development phase, well before the Stag was launched.

The reboring actually caused many of the V8's overheating problems, by causing critical areas of reduced water-flow.

Never went into anything tho did it now Mr smarty pants...
Triumph powered many different makes aswell like Saab, Marcos Mantis, TVR, Panther and Trident Tycoon, Bond, even a amphibious car from Germany

That's a good question I do recall a TR concept with a 2500 V8, I may be imagining things.

They built many concept cars, none that i know of with a v8 tho, like the TRX, TRS Conrero, Bullet, Linx an a monocoque Fury and TR250K

[ducatilover]

I'd believe it was never in production, I'm somewhat rusty on my Triumph history.
I have a mate whose father built a TR2 with a 3A fron and Alfa Running gear, the thing is beautiful, my mate owned it for a while and then it was sold on, will try find a pic. We used to call it the Tralfa.

The Stag V8´s can be made reliable now, modern antifreeze synthetic oils aftermarket chains and tensioners. As I understand the design was sound but penny pinching in the manufacturing and outsourcing caused a lot of the early issues.

Not quite what mr Austin had in mind I'm thinking

That is fucking awesome, I want!

Anyone wanna lend me an another pom car. It its defence it did beat a volvo and an HK.

I once read the V8 was a doubled up Dolomite (or the Dolly was half a Stag) any truth in that?

Would the 4 valve heads from a Dolly Sprint fit a V8? (obviously some work would be involved)

Even if it did you'd have to reverse a head so the intake is in the vee, could be interesting though, I love old multi cam motor always look grouse, the Alfa unit in that TR I posted looked horn, twin carbs off the side Sounded even better.

I didn't mention, it was running Alfa Berlina suspension front/rear. Berlina gearbox and a hot motor, 2L with a 1750 head or something silly.
