Hi does anyone know the size of the engine mount bolts on a 711m crossflow.
Regards Steve Evans.

5/16 unc.

The bolts on the block, not the rubber mounts.

The four bolts that hold the mounting to the block are 5/16 unc.

i'll second that they are 5/16 unc as i got abit over excited torqing them up and sheared a head off one in my block
luckily i managed to get it out with a stud extractor

Thanks for that I have a fit that I can take to my supplier.
Regards Steve Evans.
