1300 FWD saloon carburettor switch

[Philip Jordan]

Good day, I'm looking to switch my 1300 saloon from a single to twin carburettors, ideally to simply make it a 1300TC!  Is this a fairly easy switch and which set up is the best?  Is it the twin carb set up from a 1300 Spitfire?

Cheers

Yes, twin 1 1/4" SUs (HS2)

But be aware there are other differences so bolting twin carbs will not make a lot, if any, difference to power.

I am pretty certain camshaft, compression and possibly valve size are different. Exhaust manifold too??

Some of the early SC actually had a tubular manifold as standard, suspect it was got at by the bean counters. TC is cast iron standard one,

You will need a different camshaft, but not as easy as just fitting a Mk3 / TC one, as they run in bearings, which your block doesn't have.

Also compression is up a bit.

Triumph also fitted the TC with a servo, I drove a TC with the servo removed many years ago, brakes weren't great.

So not a straight forward mod!  I only intend using it to drive locally, the Vitesse is for the long runs out, it sounds far easier to leave standard.   I do intend fitting a brake servo for round town driving though. 

Thank you for the feedback.
