Hi
Just wanted to put a question out there to the tuners and/or suppliers etc.

Does anyone know of an 84mm billet stroked crankshaft for the 257 with a big end journal size of 55mm?

The rather lovely Crawford number comes only in 48 or 52mm size so you can only fit there internals, which would be great, but there very expensive and i already have my own Cosworth rods and pistons. I could revert to using a 83mm crank but that just isnt the point.

Thanks Sparks.

P.S
Gutted i'll miss the ESC London Tunnel run this year, It's a great event, I hope all that attend enjoy, don't forget to donate!

 

All the bigends in the 257 rods are 52mm , so if you have some rods costum made you will have to har a custom crank mande also....

But i belive you will put bearing between you 55mm rods and your 52mm bigends

But if you are going to run without bearings then you Will need a 55mm crank bigend otherwise not

 

I should have been clearer.

I wanted journals to support my 55mm con rods, sorry for the confusion. Never the less, I've just had a look on the ACL web site, I had no idea the shells were almost 1.5mm per side, i thought it was Crawford being crafty and they would have been much less.
So there was never a problem, Dont get that often.

Thanks for your input Denmark, good man.
