Hi,

Can anyone tell me what bore size a +0.040' overbore is for a std 1275 A+ block?
Is there a site or program that will tell me other overbore sizes and the applicable bore size in mm?

Many thanks,
Chris.

A .20 is 71.12mm. Add .20 to this and you get the finished bore...

Very nearly but not quite. Actually 0.508mm (or 0.51mm as would be commonly quoted)

The spreadsheet from AFRacing gives the closest figures
