Anyone who may be considering a Coscast block may want to reconsider.
A friend just contacted V8 Developments and got an interesting response from Ray Webb:
We can no longer supply Costcast blocks or short motors.
Coscast blocks do not address the problems associated with Rover blocks ie slipping liners and porosity.
We use top hated blocks as these address all the problems. The liners cannot move as they are clamped between the head face and the block
And the fitting procedure eliminates the porosity problems. We have used top hated blocks for over 30yrs and to date have had
No failures . The blocks are top hated, New cam bearings fitted, line bore checked, cam alignment checked, new core plugs fitted and the
Oil gallery plugs removed then the is block acid dipped and chemically cleaned. The cost of a top hated block on exchange is £895 + VAT. An
Outright purchase is available for £995 + VAT.
Thanks for your enquiry

If this is the case with the new Coscast blocks, then it's not worth the $$$$.
