Coscast blocks important update - they're no better, it seems.

[TRip]

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 $$$$.
