'A 'class and 'B' class blocks.. whats the sizes?

[TVR Beaver]

I was reading last time I was away about ‘A’ class and ‘B’ class blocks but I’m buggered if I can find it now…. May have been on the V8 Forum… but does anyone know the details of this… I’m assuming it applies to TVR engines also?

It was something like the bore dia was 94.05 / 94.08 on an A class.. and 94.08 / 94.11 on a B class?

Or was I just dreaming??

Absolutely no problem with that at all….
Let’s face it; you need some good bits in something that looks like that!

No... I was reading it somwewhere where the liner ID had a manufacturing tolerance... and once fitted they were graded by the size of the bore?...
Was talking to Rob today.. but he's not heard of it either?.... Will have to go back in my history.. see if I can find it again ..
