Another contribution from this side of the pond.
I had a Vic Jnr. in my previous Cob which caused significant problems in finding an air cleaner low enough to clear the bonnet (hood). It gave great performance at the top end but made the engine very lumpy and unresponsive until the revs hit 3500. Then a combination of the secondaries and the manifold made it feel like a turbo had kicked in.
I'm not sure if you got my e mail on Ralydot mountings as my home system is very erratic. Could you try me on
pderouss@ford.com as this is very reliable. (lets not use this as an excuse for the Ford v Chevy battle that seems so prevalent on the CRC site!)
