Subject: Re: 4.5 litre pushrods
Hi David
Sanction 3 push rods are longer and are also of smaller diameter, only clearing the head by a small amount.
A Sanction 3 head with integral inlet tract is deeper than the earlier sanctions which I imagine is the main reason for the difference but the crankcase was also modified / stiffened and has larger studs securing the block to the crankcase so there may be some differences in dimensions there too but I believe it is mainly the depth of the head.
Cheers
Bill
