Piston reversal.

Zero evidence.

[andypdq]

Regarding the A series, try as I might I cannot find any reference to offset cylinders or offset crank for the A series. If you can provide evidence to the contrary, I stand to be corrected.

[quote="andypdq
you obviously can't offset the crank in a V8.

Henry Ford managed it with the 1932 flathead V8 the crankshaft was offset 0.265" from centre.

Your confident delivery replying to posts made me initially confident in your omniscience, that confidence has been severely eroded recently.

I think I need to look at my A series pistons...

I must admit I don't *think* the crank is offset in the 1275s - but I may well be wrong

[andypdq]

Hi Matt, I very much doubt whether BL would have invested money in tooling up to offset the crank, small ends, maybe

Compare small bore pistons with big bore Matt, you'll see that the big bore ones have the pin in the centre. With regard to the offset, it's something that I was told many years ago, it makes perfect sense because it gives the same effect as offsetting the gudgeon pin. I've spoken to two engine builders about it in recent days, one is adamant that it's done, even though the offset is only 10-15thou, the other engineer reckons it's down to poor tolerances

The block that I have here has been bored +60, so any measurements are meaningless, but apparently it's common for FIA historic Mini's to have 'accidentally' offset cranks, we'll probably never know the truth.

[andypdq]

Feeble, lol

[andypdq]

Mike, with your incontestable omniscience I'm sure you can give us an accurate manufactured spec that the crank was offset, I understand the BL poor tolerances.

I'm sure even you can see the irony of that statement.

Zero facts in response, vacuous comment.

[andypdq]

Let's have a look at some of your claims:

V8 can't be offset, but 1932 Ford V8: cyinders are offset by o.265, see:

https://fordbarn.com/forum/showthread.p ... &showall=1

A series 1275 crank offset, no evidence whatsoever, apart from small bad BL tolerances.

You have no evidence.

The ball is in your court.

It’s becoming obvious that you don’t deserve anything more. Your other current thread shows this. How about coming back when you’ve actually done something other than talk.

[andypdq]

Forget semantics, concentrate on facts, you were wrong abut the V8 and crank offset an you're wrong about the A series too. Live in your own world, if it makes you happy Mike.

Why would they not invest in tooling when the 1275 was a completely new block and would have been tooled pretty much from scratch anyway?

Anyway Andy... how are you getting on with your build? Any results yet?

[andypdq]

Hello Matt, I think it's unlikely the A series 1275 crank was offset, it's a very uncommon configuration. I can't find any specification which says it is. It's up to those claiming it is, to provide the evidence, if anyone can provide actual specs, then I'll be more than happy to concede.
