so i have just realised i have an a series engine and not a a+.
I was just wondering was there any internal differances between them i will be building a 1330 supercharged engine. im just asking as i have already brought some omega forged pistons.
will this engine be ok or should i source an a+ engine

sorry if its a stupid question and thanks for your help

If you need a 1330 a + engine, I have a complete engine and would contemplate to sell if offered the right price?

This is a 1330 engine but was wondering if a series is just as good an engine to use as the a+. thanks

Not too sure mate, would not be able to answer that one for you. If it is not and you need a A+, then give me a shout mate

The A+ engine has no tappet covers on the 1275 block and is therefore a stronger casting, depends what power your after? If you treat it sensible then for a road car then it should be ok, there are other supercharged 1275s A series out there. If you intend to get the maximum power available then the A+ block/crank would be a stronger starting point, espicially if you intend any competition use

I'm hoping for 120-150bhp but it will be a weekend toy I have a Austin 1300 gt block and crank would that be better to use. Or should I find a a+

A+ Block and Crank is stronger,

 

The older A series standard block had a large casting hole above the centre main bearing housing and this hole has been proven to be the cause of fatigue cracks, but around 76-77 the casting hole was deleted so check on your engines if you have this casting hole to be sure. But for the kind of power your after I'd use a A+ Block for extra reliability

Thanks I will start stripping it tomorrow and see what's what. And also keep a eye out for a cheap 1275 block and crank.
