Depends what you want it to rev to. I like to use Vandeval lead/copper bearings but the ones made for Triumphs are as rare as rocking horse poo because inconsiderate racers use up a set a year! But you can get MGB and or Cooper S bearings cut down and re-drilled to fit. Costs a bit though as you have to get them bought and get them machined. I use Jigsaw to find and prepare them for me.
If you are building a non revvy engine then normal white metal berings seem to be fine.
Cambridge Motorsport have bearings in their online shop, I'm not sure what type they are but Cambridge do have some quality gear.

I notice Chris Witor has Vandervell VP2 bearings listed for the 6 cylinder engines, unsurprisingly the price is very high compared to the usual modern grades. I don't know if these are old stock or new production, I vaguely remember VP2 being reintroduced a few years ago. The 6 cylinder bearings are all common to the 4 cylinder cars, you just get some spares in each set! Check the relevant parts lists for which individual bearings are used in which applications, then get in touch with Mr Witor.

Alternatively, spend some time trawling through the autojumbles.........

Bill, Andy,
Of course my engine will br revvy
I've just got back the block/crank/rods etc - all been
lightened balanced checked straighted and all that stuff...
Canley list LC bearings as &163;39 a set - Witor charge &194;&163;48 a set (with 2 more of course) so the price isnt that extreme if they are superior.

Correction - those prices are for mains not big ends... basically for a set they're twice the price - with spares of course...

MGB bearings are for the 'large crank' engines and need to be filed on the tang to make them fit (I think you call that bit a tang?).
Cooper S bearing are for 'small crank' engines, but my engine builder does mine so I have no idea how you machine them... ?-

Details are on my website under the 'sponsors' link (if you can find it - it's a test of worhtiness)
... I actually don't think they need that much machining... just narrowing a bit!-

The machine shop I use has been able to supply the Pb/In/Cu shells without any problem but at the expected price premium.
I have dismantled engines which I have built with Sn base bearings which I have thrashed and I have seen the white metal beginning to break up.

Strangely enough I was talking to my engine builder about just this thing yesterday.
Opinion was, if you're building a 'fastroad' engine then you are perfectly fine using the normally available whitemetal/aluminium bearings. Reasons given were that once any crap gets into them, these bearings will do less damage whereas lead/copper lead/brass, being much softer, will quickly be destroyed.
Other thoughts were...
A 'fastroad' engine still needs to get you home, whereas a race engine doesn't - therefor some 'robustness' needs to be built in.
You're unlikely to be running your 'fastroad' engine above 6000 rpm for very long (if at all) - although it can easily do it, it is very noisey - we racers have helmets on and ear plugs.
For every 7500 rpm you have to do, you have to do 3500 twice - these 'harder' bearings work better at these ranges.
There was more, but I can't remeber it... we did waffle on for a while!
In a nutshell, I'd use MGB bearings with a filed 'tang' for large cranks - wider than spitfire bearings.
and Shaved A+ bearings for small cranks (Metro - as Jon says).
Not expensive and perfectly up to the job.-

Cheers Nigel.
Well I can get some nice Metro bearings from the Mini Shop - so that'll be the way I'll go...
As for all this "not above 6,000" - bahumbug! My motto; To the redline, everytime... *cheeky smile*

hehe... you'll learn alot about engines then in the next year or so as you'll have to do about four rebuilds *lol*-

Ok - I've got the lowdown off of Dermot...
For the mains you use late Metro 1275 bearings - they fit straight in.
For the big ends you use Cooper S bearings - but you have to take off 1/8" the sides.
In his opinion - the only way to get decent bearings for a 1300.
