The Triumph Toledo V8 Revs Up

The project V8-engined Toledo stirs a little more from it's two year slumber.

At the moment it's suffering a fuelling issue which is either the wrong main jets, incorrect setup or a blockage somewhere - consequently it only runs on what you pour (or pump) down it's throat or if you get the throttle open enough to get the mains running, as seen in the video.

This, however, is easily resolved - and the engine's sounding great so far.

rover v8 may have been a better choice, what gearbox did u use?

[LashoutUK]

The Rover's a good engine - had one in another Dolly previously - but this is supposed to be a sorta 'factory car they never built' affair.

This engine revs better and makes more power than a stock 3.5, so has it's benefits - head gasket issues are not exclusive to the Stag V8 at any rate, if uncared for!

The gearbox is a mishmash of TR6, Stag & Sprint parts - can never recall which! 4 speeds with overdrive on 3rd and 4th, driving a Sprint rear axle.

I had a dolomite 1300, friend had the 2000 I6 version of same engine out of a vitesse, I think that would bolt onto standard 1300 bellhousing etc.

Do u think the 2000 or even the 2500 (were they same block with different strokes and bore?) would fit length wise?

that would be cool, a 2500 with triple 45 dcoe carbs and 285 cam etc.

Cool!

Oddly enough (haha) - I had a 1500 (ex-FWD) that had been mocked up with a 2500 PI & powertrain (later became a Sprint).

The problem was that without really modifying the bulkhead or transmission tunnel, I don't think you could get the engine far back enough to get a sensible radiator or cooling system in.

Would have made a hell of a machine though - and I've seen a 2.5 PI one done, so it's possible! I suspect there are ways around it, like split superthin rads etc...

........it's a big, heavy engine too - so quite a weight to hang that far out over the nose in the Dolly - something else that bothered me slightly.

I think the 1300/1500s use a much smaller gearbox than the sixes/Sprints due to the lower torque outputs - so I'm not sure it'd be a direct swap. Easy to fit one of the 'big' boxes into a 1300 anyway, as the Sprint used them so all the mountings would be available! :)

this triumph came with v8 or is fited one in please let me know the only i know is 4 cyl.

[LashoutUK]

Hi there - this is not a standard engine, indeed you are correct - all Toledos came with 4 cylinders.

This Stag V8 was fitted using a modified Triumph subframe so in some respects "just bolted in" but was also an awful lot of work in other areas to get it all in.

If the motor is backfiring due to slow cranking,,,charge the battery!!!!. if you have flames sitting in the carb after a backfire,,crank the motor to pull the falmes out,,dont stand there staring and blowing,, and let the flames burn the insulator gasket or base gasket,,because then you have a air leak. Neat engine! keep up the work.

Great choice of Engine. would love to see a TR7 with one fitted.
